The current limit is resistor settable from 0.075A to 1.5A and features an adjustable soft-start function to control the output-voltage ramp rate, thereby limiting the inrush current. It also has an adjustable blanking time to accommodate various capacitive loads. If the load current is greater than the current-limit threshold, the current limiter handles the overcurrent situation in one of three ways depending on the option selected. It enters an autoretry mode (MAX4766A), latches off the switch (MAX4766B), or places the device in a continuous current-limit mode (MAX4766C). Additional safety features include thermal shutdown to prevent overheating and reverse-current blocking to prevent current from being driven back into the source. The MAX4766 is available in a tiny 8-pin 3mm x 3mm TDFN package and operates over the extended temperature range of -40C to +85C.
