Smart fuse high side switch controller reference design

TIDA-020065

Design files

Overview

This reference design overcomes challenges commonly associated with replacing the standard melting fuse. By implementing the TPS1213-Q1 high-side switch controller, INA296B-Q1 current sense amplifier, and a microcontroller, this design provides I2 t overcurrent protection, low-power mode to minimize power consumption, and the capability of driving resistive, capacitive, and inductive loads. The design contains many configuration options, including bidirectional current sense, that allows engineers to run a variety of tests for high-current smart fuse applications.

Features
  • Software-based I2t fuse algorithm through MSPM0L1306-Q1
  • Prevents uncontrolled inrush current at start-up through gate slew-rate limiting circuit for driving capacitive loads
  • 38μA in low-power mode (without MSPM0L1306- Q1)
