9.1 Overview

The TPS1663x is a family of 60-V industrial eFuses. The device provides robust protection for all systems and applications powered from 4.5 V to 60 V. For hot-pluggable boards, the device provides hot-swap power management with in-rush current control and programmable output voltage slew rate features using the dVdT pin. Load, source, and device protections are provided with many programmable features including overcurrent, overvoltage and undervoltage. The 60-V maximum DC operating and 62-V absolute maximum voltage rating enables system protection from 60-V DC input supply faults from industrial SELV power supplies. The precision overcurrent limit (±7% at 6 A) helps to minimize over design of the input power supply, while the fast response short circuit protection 1 µs (typical) immediately isolates the faulty load from the input supply when a short circuit is detected.

The TPS16632 device integrate adjustable output power limiting (PLIM) functionality that simplifies the system design requiring compliance in accordance to standards like IEC61010-1 and UL1310.

The device provides precise monitoring of voltage bus for brown-out and overvoltage conditions and asserts fault signal for the downstream system. The device's overall threshold accuracy of 2% ensures tight supervision of bus, eliminating the need for a separate supply voltage supervisor chip.

Additional features of the TPS1663x include:

  • ±6% current monitor output (IMON) for health monitoring of the system
  • A choice of latch off or automatic restart mode response during current limit, power limit, and thermal fault using MODE pin
  • PGOOD indicator output
  • Overtemperature protection to safely shutdown in the event of an overcurrent event
  • De-glitched fault reporting for supply brown-out and overvoltage faults
  • Enable and Disable control from an MCU using SHDN pin
