TPS2560DRCT

Power Distribution Switches, Load Drivers Overview

The TPS2560DRCT is a dual-channel power distribution switch manufactured by Texas Instruments, designed for high-side load switching applications. It features an N-channel output configuration with a maximum continuous output current of 2.5 A per channel. The device operates within a load voltage range of 2.5 V to 6.5 V and includes adjustable current limiting from 250 mA to 2.8 A. Key electrical parameters include a typical on-resistance of 44 mΩ and a maximum on-resistance of 50 mΩ. The IC incorporates controlled slew rate functionality and status flags for system monitoring. Protection mechanisms include adjustable current limit, over-temperature shutdown, and under-voltage lockout (UVLO). It supports a non-inverting open/switch interface and functions without a separate supply voltage. The component is rated for junction temperatures between -40°C and +125°C and is housed in a 10-VSON (3x3 mm) package.
