Overview

The TPS1685EVM is used to evaluate the performance of the TPS1685 eFuse device. The TPS1685EVM comes with two TPS16851 eFuses connected in parallel to evaluate a 54V (typical) and 40A (steady state) design. This evaluation module incorporates two TPS16851 devices in parallel, which supports a 2kW input power path protection design at an input voltage of 48V.

Features
  • 40V to 54V (typical) operation
  • 25A and 44A programmable circuit breaker threshold using on-board jumpers
  • Adjustable reference voltage (VIREF) for overcurrent, short-circuit protection, and active current sharing blocks through VIREF (32h) register
  • Adjustable output voltage slew rate control both in hardware and firmware
  • Adjustable transient current blanking timer in firmware through OC_TIMER (14h) register
  • Adjustable active current sharing threshold using on-board jumpers
eFuses (integrated hot swaps)
TPS1689 9V to 80V, 3.65mΩ, 20A stackable integrated hot swap (eFuse) with PMBus digital telemetry
