The IC controls two n-channel MOSFETs that deliver up to 40A of output current. The EV kit circuit ensures that the output voltage is stable and within the undervoltage (UV) and overvoltage (OV) thresholds. The circuit continually monitors load current to ensure that it does not exceed the circuit programmable fast and slow current-limit thresholds. The EV kit circuit provides a buffered output of the IC's current-sense amplifier and includes a precision current source providing a 2.5V output when enabling the IC's calibration-mode function.
The EV kit can also be used to evaluate the MAX5977B autoretry hot-swap controller after IC replacement of U1.
