description
The TPS2310 and TPS2311 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 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.
