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 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.
