Micrel previews industry`s hottest new power solutions at IIC China

Chengdu (ANTARA News/PRNewswire-AsiaNet) - Micrel Inc., (Nasdaq: MCRL), an industry leader in IC analog, high bandwidth and Ethernet solutions, today announced that it would be previewing the industry's newest and most innovative power analog IC solutions at the 13th Annual International IC-China Conference & Exhibition.

The show will be held in four locations this year: Chengdu (Feb. 28-29); Shenzhen (March 3-4); Beijing (March 6-7); and Shanghai (March 10-11), China.

Micrel will also participate in the IIC Power Management and Automotive Electronics Vendor Seminars with the schedule detailed as follows . Power Management Vendor Seminars: Chengdu, Feb. 28, 13:30-14:20 p.m.; Shenzhen, March 3, 13:30-14:20 p.m.; Beijing: March 6, 13:30-14:20 p.m.; and Shanghai, March 10, 13:30-14:20 p.m. Automotive Electronics Vendor Seminars: Chengdu, Feb. 28, 15:40-16:30 p.m.; and Shenzhen, March 4, 14:40-15:30 p.m.

Included in the preview will be a fully-integrated 4A synchronous buck regulator, the MIC22400 for 3V and 5V supply rails. With operating frequency programmable from 800KHz to 4 MHz, the IC features built-in sequencing, tracking and ramp control, enabling all power-up sequencing and tracking protocols.

Targeted at the communications, computing peripherals, and high- end consumer markets, the solution is ideal for servers routers, HD DVD recorders, wireless base stations, FPGAs, DSPs, and low voltage ASICs, as well as other high power density applications.

The Company will also preview the MICRF218 the world's first programmable receiver featuring jam avoidance. The MICRF218, which is part of Micrel's QwikRadio(R) family, is targeted at garage door openers and tire pressure monitoring systems. It is the world's first integrated ASK/OOK receiver with selectable IF bandwidth for 300 to 450 MHz operation.

Finally, Micrel will also showcase the MIC94064/5, a series of high-side load switches that extend Micrel's industry-leading MIC9406 x family of high-side load switch products. The MIC9406 x family now covers a wide range of battery-powered consumer and industrial applications that require a variety of turn-on characteristics, including portable computers, cell phones, and personal media devices.

"Micrel's breadth of analog products now includes more than more than 1,500 solutions including Low Noise Regulators (LDOs), Switchers, Switches (USB, High Side, Cable), Hot Swap Controllers, Power Management, MOSFET Drivers, Voltage References, and Power Supervisors," noted Andrew Cowell, Micrel's vice president of marketing for analog products.

"These new devices, from the world's first programmable receiver featuring jam avoidance, to a the smallest fully-integrated 4A synchronous buck regulator for 3V and 5V supply rails, demonstrate Micrel's on-going commitment to providing China with the most innovative and advanced ICs on the market today."

Micrel announces two new soft-start high side power switches

San Jose, California, (ANTARA News/PRNewswire-AsiaNet) - Micrel Inc., (Nasdaq: MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today launched the MIC94064/5, a series of high-side load switches that extend Micrel's industry-leading MIC9406x family of high-side load switch products.


The MIC9406x family now covers a wide range of battery-powered consumer and industrial applications that require a variety of turn-on characteristics, including portable computers, cell phones, and personal media devices. The MIC94064/5 series is currently available in volume quantities, with pricing starting at $0.37, for 1K quantities.

"A natural extension of our highly successful MIC94060/1/2 3, the new MIC94064/5 devices offer our customers even more design flexibility than ever before," noted John Lee, director of mixed-signal and RF products, Micrel. "With the introduction of the MIC94064/5 series, our customers can now pick a device from the MIC9406x family with a turn-on time that is optimized for their specific applications."

The MIC94064/5 offer an output voltage turn-on time of 115 micron s, complementing the less than 1 micron turn-on time for the MIC94060/1 and 800 micron s turn-on time for the MIC94062 3. The MIC9406x feature a typical R(DSON) of 77mohm. The devices operate with inputs ranging from 1.7V to 5.5V. Each solution can be driven by a low 1.5V logic level, which is accomplished by incorporating a novel built-in level shift circuitry that allows low voltage logic to control higher voltage supplies.

Battery time is greatly extended in portable applications due to the low operating current of 2 micron A and a shutdown current of less than 1 micron A. The MIC94064/5 have a slew rate controlled turn-on time of 115 micron s (typical) that prevents in-rush current. In addition, the MIC94065 provides an active load discharge circuit that insures capacitive loads retain no charge when the main switch is in an OFF state. The MIC94064/5 series are available housed in the thin 4-pin 1.2mm x 1.6mm MLF(R) and Teeny(TM) SC-70-6 packages.

Micrel announces new Dual-Channel Hot-Plug Power Controllers

San Jose, California, (ANTARA News/PRNewswire-AsiaNet) - Micrel Inc., (Nasdaq: MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today launched the MIC2341 and MIC2342. The devices are Dual Channel Hot-Plug Power Controllers that support the power requirements for PCI Express Specification v2.0.

The MIC2341 and MIC2342 augment Micrel's growing PCIe product family and are ideal for high performance enterprise computing network system processor boards, DDR memory boards, embedded systems and gigabit Ethernet add-in cards for the server networks and RAID/storage network markets. The devices are currently available in volume quantities and are priced at $4.54 for 1K quantities.

"The MIC2341 and MIC2342 both offer an integrated solution that minimizes solution component count and lower overall BOM cost," noted Andy Cowell, Micrel's marketing vice president for analog products. "In addition, both ICs feature very rapid response times to potentially catastrophic overcurrent load events, key in mission-critical applications for the server and RAID/storage network markets."

The MIC2341 and MIC2342 provide support for 12V, 3.3V, and 3.3VAUX supplies and are equipped with many features -- including programmable gate voltage slew-rate control, voltage supervision, programmable current limit, and circuit breaker functions. The devices support two independent PCI Express slots, offer integrated power MOSFETS for 3.3VAUX rails with low backfeed on the MAIN +12V and +3.3V rails, an important consideration during standby operation for Wake-on-LAN applications.

The ICs also offer dual-level, dual-speed overcurrent fault protection and a user-programmable primary overcurrent filter to eliminate nuisance tripping. Separate MAIN and AUX overcurrent fault output signals and load card detection (present) switch inputs are also offered. Power will be delivered only when the module/card is fully inserted and power fault isolation allows an unaffected power rail(s) to remain active and accelerates debugging effort(s) when locating a faulty area(s) in the circuit. In addition, the ICs provide system management flexibility in offering either a latched or auto-retry option.

The MAIN output rails of the MIC2342 shut down during an overcurrent fault on AUX for a given slot, whereas MAIN outputs of the MIC2341 are independent of an overcurrent fault occurring on AUX. Both ICs are available in RoHS compliant 48-pin TQFP Pb-free package. All options feature a 0-deg C to +70-deg C ambient temperature range.
