The TPS2459RHBR from Texas Instruments is an active hot swap controller and OR controller designed for robust power management in ATCA and MicroTCA systems. It supports an input voltage range from 3V to 15V, with a maximum continuous voltage of 17V.
Key electrical specifications include a current rating of 165mA and a low quiescent current, typically 1nA and a maximum of 5nA. The device offers adjustable current limit, adjustable soft start, current monitoring, and protection features such as overcurrent protection, short circuit protection, and thermal shutdown. It also includes a power good signal and reverse current blocking.
This controller features I2C communication for fault reporting and programmable fault times and limits. It operates within an industrial temperature range of -40°C to 85°C. The TPS2459RHBR is housed in a 32-pin VFQFN exposed pad package, measuring 5mm x 5mm, suitable for surface mounting.
Its programmable features include auto-retry, circuit breaker functionality, and latched fault response, making it suitable for applications requiring reliable power sequencing and protection.
