Description

The TPS2022D is a Power Distribution Switch intended for applications where heavy capacitive loads and short circuits are likely to be encountered. This device is 50mR N-channel MOSFET high-side power switches. The switch is controlled by a logic enable compatible with 5V logic and 3V 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 2.7V. When the output load exceeds the current-limit threshold or a short is present, the TPS202x limits the output current to a safe level by switching into a constant-current mode, pulling the overcurrent (OC) 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.
