TPS2002CDRCR

Power Distribution Switches, Load Drivers Overview

The TPS2002CDRCR is a dual-channel power distribution switch manufactured by Texas Instruments. It features an N-channel MOSFET topology with a continuous current rating of 2 A per channel and a maximum load voltage range of 4.5 V to 5.5 V. The device operates within an ambient temperature range of -40°C to +85°C and utilizes a 10-VSON (3x3) surface-mount package. Key electrical specifications include a typical on-resistance (Rds(on)) of 70 mΩ and a fast overcurrent response time of 2 μs. The enable function is active-low, providing precise control for power sequencing applications.
