description

The TPS2300 and TPS2301 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,

output-power

status

reporting,

and

separation of load transients from actual load

increases, are critical requirements for hot-swap

applications.

The TPS2300/01 devices incorporate undervoltage lockout (UVLO) and power-good (PG) reporting to ensure

the device is off at start-up and confirm the status of the output voltage rails during operation. 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.
