DESCRIPTION
The TPS204xB/TPS205xB power-distribution switches are intended for applications where heavy capacitive
loads and short circuits are likely to be encountered. These devices incorporate 70-m
N-channel MOSFET
power switches for power-distribution systems that require multiple power switches in a single package. Each
switch is controlled by a 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 device 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 that the switch remains
off until valid input voltage is present. This power-distribution switch is designed to set current limit at 1 A (typ).
