MAX14523A/B/C: Programmable Current-Limit Switches Protect Host Devices from Faulty Loads

Maxim has introduced the MAX14523A/MAX14523B/MAX14523C, a family of adjustable current-limit switches. These overcurrent limiters offer a ±10% accurate current limit that can be programmed from 250mA to 1500mA with an external resistor. The MAX14523A/B/C protect host devices against damage caused by faulty load conditions, and provide reverse-current blocking to prevent current from being dumped back into the source. These tiny devices have a very low shutdown current (0.5microamps), making them ideal for cell phones, MP3 players, and other battery-powered applications.

Packaged in a lead-free, 3mm x 3mm, 8-pin TDFN, the MAX14523A/B/C are fully specified over the -40 degrees Celsius to +125 degrees Celsius automotive temperature range.
