The
TPS2320
and
TPS2321
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,
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.
