TPS2032 General Description

The TPS203x 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-mΩ 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 TPS203x 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. 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.

The TPS203x devices differ only in short-circuit current threshold. The TPS2030 limits at 0.3-A load, the TPS2031 at 0.9-A load, the TPS2032 at 1.5-A load, the TPS2033 at 2.2-A load, and the TPS2034 at 3-A load (see Available Options). The TPS203x is available in an 8-pin small-outline integrated-circuit (SOIC) package and in an 8-pin dual-in-line (DIP) package and operates over a junction temperature range of −40°C to 125°C.
