Adjustable current-limit switches to protect 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 (0.5µA), making them suitable for cell phones, MP3 players, and other battery-powered applications.

Operating temperature range: -40°C to +125°C

Package: 3mm x 3mm, 8-pin TDFN package
Price:
MAX14523A/B/C: Starts at $1.26 for 1k pieces
