TPS2419PWR

Overview

The TPS2419PWR is a hot swap voltage controller manufactured by Texas Instruments, designed for N+1 and ORing power rail applications. It operates with an external N-channel MOSFET to provide reverse current protection with high efficiency. The device supports bus voltages from 3V to 16.5V and features a quiescent current of 1.2mA. It includes programmable shutdown thresholds, soft-start functionality, and an enable pin for forced MOSFET turn-off in light-load or high-noise conditions. The component is housed in an 8-TSSOP package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

Controls external N-channel MOSFETs to implement efficient ORing diode emulation for reverse current protection.
Supports N+1 redundancy configurations and redundant input power bus combining.
Features programmable shutdown thresholds and an enable pin for system-level control under specific load conditions.

Applications

N+1 redundant power supplies
Server blade power modules
Telecommunications systems
High-availability power distribution units

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the 8-TSSOP tube packaging variant when sourcing. Confirm that the required operating voltage range aligns with the 3V to 16.5V specification. Ensure the design utilizes an appropriate external N-channel MOSFET compatible with the gate drive capabilities. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this controller for designs requiring precise voltage sensing and customizable shutdown thresholds. It is suitable for systems needing fast device shutdown to protect bus integrity during faults. Consider the external FET selection carefully to match the gate drive current requirements. The integrated soft-start feature helps minimize bus transients during power-up sequences.

Part Context

This component belongs to the TPS241x series of power management ICs focused on ORing controllers and ideal diode emulation. It complements other variants like the TPS2413 by offering specific threshold programming options. The series targets robust power distribution architectures where redundancy and fault isolation are critical for system uptime.
