TPS2410PWR

Overview

The TPS2410PWR is a single-channel Hot Swap Voltage Controller manufactured by Texas Instruments, designed for N+1 and OR-ing power rail applications. It operates within an input voltage range of 800 mV to 16.5 V and features programmable current limiting. The device supports both linear and on/off control methods, utilizing an internal charge pump to drive external N-channel MOSFETs. It includes power failure detection and soft turn-on capabilities to reduce bus transients during hot insertion. The component functions reliably across an industrial temperature range of -40°C to +85°C with a typical operating supply current of 1.2 mA.

Feature Summary

• Supports N+1 redundancy and OR-ing configurations using external N-channel MOSFETs
• Provides programmable current limiting with linear or on/off control modes
• Integrates power failure detection and soft turn-on functionality

Applications

• N+1 redundant power supplies in server architectures
• Redundant power bus combinations in telecom systems
• High availability system power distribution

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the selected variant matches the required thermal performance and pinout configuration for the target PCB layout. Cross-reference the datasheet revision history to confirm compatibility with existing design parameters.

Selection Notes

Select this controller when designing systems requiring precise current limiting and fault protection for redundant power sources. It is suitable for applications needing diode-OR emulation with lower power loss than Schottky diodes. Consider the TSSOP-14 package constraints and the requirement for external MOSFET selection based on the programmable threshold settings.

Part Context

This component belongs to the TPS2410 series of Hot Swap Voltage Controllers from Texas Instruments. It serves as a specialized power management IC for protecting buses during hot insertion and managing multiple power inputs. The series is distinct from other logic or buffer families produced by the manufacturer, focusing specifically on high-voltage power rail control and redundancy management.
