TPS2044BD

Power Distribution Switches, Load Drivers Overview

The TPS2044BD is a quad current-limited power distribution switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features four independent high-side outputs. The device provides a maximum output current of 500 mA per channel with a hard current limit of 1 A. Key electrical parameters include a maximum on-resistance of 135 mOhms, a maximum turn-on time of 3 ms, and a maximum turn-off time of 10 ms. It is housed in a 16-pin SOIC-Narrow package and supports an operating temperature range from -40°C to +85°C.
