TPS2557QDRBRQ1 Description

Short technical summary and product information.

The Texas Instruments TPS2557QDRBRQ1 is a precision automotive adjustable current-limited power distribution switch designed for robust power management applications. It operates with an input voltage range of 2.5V to 6.5V and provides an adjustable current limit from 500mA to 5A, with a typical accuracy of ±6.5% at 4.5A. The device features a low 22mΩ typical on-resistance (RDS(on)) N-channel MOSFET.

 

Key features include a fast short-circuit response time of 3.5µs, built-in soft-start functionality, and comprehensive fault protection including current limiting, over-temperature protection, and undervoltage lockout (UVLO). The switch is enabled by an active-high signal and includes a status flag. It is designed to meet USB current-limiting requirements and offers system-level ESD protection up to 15kV.

 

Packaged in an 8-SON (3x3) or 8-VDFN exposed pad, the TPS2557QDRBRQ1 is suitable for surface mount applications. It operates within an ambient temperature range of -40°C to 125°C (TJ) and is qualified to AEC-Q100 standards, making it ideal for demanding automotive environments. The device is also Functional Safety-Capable, with documentation available to aid functional safety system design.
