description
The TPS2090, TPS2091, and TPS2092 dual and
the TPS2095, TPS2096 and TPS2097 quad
power-distribution switches are intended for
applications where heavy capacitive loads and
short circuits are likely to be encountered. The
TPS209x devices incorporate 80-m
N-channel
MOSFET high-side power switches for power-distribution systems that require multiple power switches in a
single package. Each switch is controlled by an independent logic enable input. Gate drive is provided by an
internal charge pump designed to control the power-switch rise times and fall times to minimize current surges
during switching. The charge pump requires no external components and allows operation from supplies as low
as 2.7 V.
When the output load exceeds the current-limit threshold or a short is present, the TPS209x limits the output
current to a safe level by switching into a constant-current mode, pulling the overcurrent (OCx) logic output low.
When continuous heavy overloads and short circuits increase the power dissipation in the switch causing the
junction temperature to rise, a thermal protection circuit shuts off the switch to prevent damage. Recovery from
a thermal shutdown is automatic once the device has cooled sufficiently. Internal circuitry ensures the switch
remains off until valid input voltage is present. The TPS209x devices are designed to current limit at
0.5-A load.
