资 源 简 介

The TPS2320 and TPS2321 are dual-channel hot-swap controllers that use external N-channel MOSFETs as high-side switches in power applicaTIons. Features of these devices, such as overcurrent protecTIon (OCP), inrush-current control, and the ability to discriminate between load transients and faults, are criTIcal requirements for hot-swap applicaTIons. The TPS2320/21 devices incorporate undervoltage lockout (UVLO) to ensure the device is off at startup. Each internal charge pump, capable of driving multiple MOSFETs, provides enough gate-drive voltage to fully enhance the N-channel MOSFETs. The charge pumps control both the rise times and fall times (dv/dt) of the MOSFETs, reducing power transients during power up/down.
