Maxim Integrated Products launches the MAX14523A/MAX14523B/MAX14523C adjustable current-limit switches.

These over-current limiters offer a ±10 per cent 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 also have a very low shutdown current (0.5µA).

Applications include 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°C to +125°C automotive temperature range.

Pricing for the MAX14523A/MAX14523B/MAX14523C starts at Rs.61.51 ($1.26) (1,000-up, FOB USA).
