General Description

The ON Semiconductor’s SmartORt CMPWR280 is a fully protected Dual−Input low−dropout CMOS regulator that also provides the necessary control signal for driving an external auxiliary P−channel MOSFET switch.

The SmartORt device automatically selects one of three possible inputs on a priority basis: VCC (1.5 A), VSBY (375 mA) or VAUX via the drive signal used to control an external switch.

VCC is given first priority.
