DESCRIPTION
The TPS2310 and TPS2311 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,
output-power status reporting, and the ability to
discriminate between load transients and faults, are
critical requirements for hot-swap applications.
The TPS2310/11 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.
