DESCRIPTION

The TPS2320 and TPS2321 are dual-channel hotswap

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.

A

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. The circuit-breaker functionality combines the ability to sense

overcurrent conditions with a timer function; this allows designs such as DSPs, that may have high peak currents

during power-state transitions, to disregard transients for a programmable period.
