TPS23525PWR

The Texas Instruments TPS23525PWR is an active hot swap controller and OR controller designed for robust power management in -48V systems. It operates within an input voltage range of -10V to -80V, with an absolute maximum continuous voltage of -200V.

Key features include adjustable current limit, adjustable soft start, fault output, overcurrent protection, overvoltage protection, a power good signal, and always-on reverse current blocking. The device provides short circuit protection and an adjustable UVLO (Under-Voltage Lockout). Its fault response mechanism includes auto-retry, and overvoltage response is handled by cut-off.

This controller is housed in a 16-TSSOP package, suitable for surface mount applications. The operating temperature range is from -40°C to 125°C. It is ideal for applications such as network routers and switches requiring reliable -48V power.

With a quiescent current of typically 1 mA, the TPS23525PWR offers efficient operation. It also features programmable UVLO and OV with specific tolerances, and programmable hysteresis. The integrated dual OR-ing controller ensures proper power flow management.
