Overview
The TPS2024DR is a high-side power distribution switch manufactured by Texas Instruments. It is part of the TPS202x family, designed to handle applications with heavy capacitive loads and potential short circuits. This device features a 33-mΩ N-channel MOSFET switch, controlled by a logic-level enable input compatible with both 5-V and 3-V logic. The switch operates within a voltage range of 2.7 V to 5.5 V and is available in 8-pin SOIC and PDIP packages. The TPS2024DR is particularly suited for applications requiring robust protection against overcurrent and thermal issues, with automatic recovery from thermal shutdowns once the device has cooled sufficiently.
