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.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
