The TPS206x power-distribution switches are intended for applications where heavy capacitive loads and
short-circuits are likely to be encountered. This device incorporates 70-m
Ω 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 1.5 A
typically.
