TPS2045 Datasheet Current-limited Power-distribution Switches

Manufacturer: Texas Instruments

Overview: TPS2045, TPS2055 CURRENT-LIMITED POWER-DISTRIBUTION SWITCHES.

General Description

The TPS2045 and TPS2055 power-distribution switches are intended for applications where heavy capacitive loads and short circuits are likely.

Each of these 135-mΩ N-channel MOSFET high-side power switches is controlled by a logic enable patible with 5-V and 3-V logic.

Gate drive is provided by an internal charge pump that controls the power-switch rise times and fall times to minimize current surges during switching.
