Machine-Model ESD Protection

The TPS201xA family of power distribution switches is intended for applications where heavy capacitive loads

and short circuits are likely to be encountered. These devices are 50-m

Ω N-channel MOSFET high-side power

switches. The switch is controlled by a logic enable compatible with 5-V logic and 3-V logic. 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 TPS201xA limits the output

current to a safe level by switching into a constant-current mode. 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.
