TPS23521PWR Description

Short technical summary and product information.

The Texas Instruments TPS23521PWR is an active hot swap controller with a wide operating voltage range from -10V to -80V, and an absolute maximum continuous voltage of -200V. This device is suitable for -48V applications, including network routers and switches.

 

Key features include adjustable current limit, adjustable soft start, fault output, overcurrent protection, overvoltage protection, and a power good signal. The overcurrent response is managed via a circuit breaker and current limiting, with an auto-retry fault response. It also offers programmable UVLO and OV with hysteresis.

 

The TPS23521PWR is housed in a 16-TSSOP package, designed for surface mount installation. It operates within a temperature range of -40°C to 125°C. The typical quiescent current is 0.001A.

 

This controller provides essential power protection features for robust system operation in demanding environments.
