description

The TPS2080, TPS2081, and TPS2082 dual and

the TPS2085, TPS2086 and TPS2087 quad

power-distribution switches are intended for

applications where heavy capacitive loads and

short circuits are likely to be encountered. The

TPS208x devices incorporate 80-m

Ω 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 TPS208x 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 TPS208x devices are designed to current limit at 1.0-A load.
