Programmable current-limit switches help protect host devices from faulty loads

Maxim Integrated Products has introduced the MAX14523A/MAX14523B/MAX14523C, a family of adjustable current-limit switches that claims to offer a ±10 percent accurate current limit which can be programmed from 250 mA to 1500 mA 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 (0.5 uA), making them ideal for cell phones, MP3 players, and other battery-powered applications.

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

Pricing

Prices start at $1.26 (1000-up, FOB USA).
