TPS2066ADRBT

Power Distribution Switches, Load Drivers Overview

The TPS2066ADRBT is a dual-channel power distribution switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and provides two independent outputs with a continuous output current of 1 A per channel. The device features an adjustable current limit set at 1.5 A and a maximum on-resistance of 135 mOhms. It includes soft-start functionality with a maximum ramp time of 3 ms and an idle time of up to 10 ms. The component is housed in an 8-VDFN (3x3 mm) package with an exposed pad, suitable for surface mount applications across a temperature range of -40°C to +85°C.
