Overview
CALIFORNIA MICRO DEVICES CMPWR160 USB Peripheral Power Management Features • 3.
3V regulated output up to 500mA • Quiescent current 35µA (typical) • Shutdown mode current 7µA (typical) • 30ms active LOW Power-On Reset (POR) pulse • Thermal overload protection • Foldback current limiting protection • Reverse-current protection • 8 pin SOIC power package Applications • Bus-powered USB peripherals • Self-powered USB peripherals • Portable/battery-powered devices • Critical power monitoring, hot-insertion devices The SmartORTM CMPWR160 combines a Low Dropout Regulator (LDO) with a Power-On Reset (POR) pulse generator, and is intended for Universal Serial Bus (USB) peripherals.
To meet the specification requirements of both USB 1.
0 and USB 2.
0, the CMPWR160 draws a very low quiescent current (35µA), and delivers up to 500mA of load current at a fixed 3.
3V output.
The POR pulse (active LOW) has a typical duration of 30ms after the output has exceeded and stabil...
