TPS2032DR

The Texas Instruments TPS2032DR is part of the TPS203x family of power distribution switches. These devices are N-channel MOSFET high-side power switches with an on-resistance of 33 mΩ at a 5-V input. They are designed to handle applications where heavy capacitive loads and short circuits are likely.

The TPS2032DR operates over a voltage range of 2.7 V to 5.5 V and includes features such as short-circuit protection, thermal protection, and undervoltage lockout. The switch is controlled by a logic-level enable input compatible with 5-V and 3-V logic. An internal charge pump manages rise and fall times to minimize current surges during switching.

When an output load exceeds the current-limit threshold or a short circuit occurs, the device limits output current to a safe level and activates an overcurrent logic output. Thermal protection circuitry shuts off the switch if junction temperature rises due to continuous overloads, with automatic recovery once cooled. The device is available in 8-pin SOIC and 8-pin PDIP packages.

Key electrical characteristics include a typical rise time of 6.1 ms and a maximum standby supply current of 10 µA. ESD protection is rated at 2 kV for the Human-Body-Model and 200 V for the Machine-Model. The ambient operating temperature range is -40 °C to 85 °C, with a junction temperature range of -40 °C to 125 °C.
