CAMD Intros CMPWR160 IC

December 04, 2000 by Jeff Shepard

California Micro Devices Corp. (CAMD, Milpitas, CA) has announced the availability of its CMPWR160 integrated circuit (IC) which is designed to provide an integrated power management solution targeting Universal Serial Bus (USB) peripherals and other hot insertion equipment.

The CMPWR160 combines an LDO with a power-on-reset pulse generator. To meet the specification requirements of both USB 1.0 and USB 2.0, the CMPWR160 draws a 35µA quiesecent current while delivering up to a 500mA of load current at a fixed 3.3V output. The LDO is implemented using CAMD's SmartOR technology.

A shut-down feature is included on the CMPWR160, which can force the regulator to be powered down on demand while drawing 7µA of current. When in shut-down mode, the power-on-reset circuitry will remain active, making the device suitable for systems that contain back-up or alternative power sources.

The CMPWR160 is suited to use in self-powered and bus-powered USB peripherals. Typical peripherals include keyboards, digital cameras, storage devices, audio speakers, microphones and video game controls such as joysticks.

The CMPWR160 is packaged in a thermally-enhanced 8-pin SOIC. This package uses a fused leadframe where the ground pins are integral to the leadframe so that a double-sided printed circuit board can act as a heat-spreader. The new piece is available in 10,000-piece quantities for $0.84 each. Samples are currently available.
