TPS2321 DUAL HOT SWAP POWER CONTROLLERS

AGND DGND TPS2320 FAULT The TPS2320 and TPS2321 are dual-channel hot- ENABLE TIMER swap controllers that use external N-channel MOSFETs as high-side switches in power IN2 ISET2 ISENSE2 GATE2 DISCH2 applications. Features of these devices, such as overcurrent protection (OCP), inrush-current control, and the ability to discriminate between load tra.
