DESCRIPTION

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-mΩ N-channel MOSFET power switches

for power-distribution systems that require single or dual 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. Current limit is typically 2.1 A.
