DESCRIPTION
The LTC®1759 Smart Battery Charger is a single chip charging solution that dramatically simplifies construction of an SBS compliant system. The LTC1759 implements a Level 2 charger function whereby the charger can be programmed by the battery or by the host. A thermistor on the battery being charged is monitored for temperature, connectivity and battery type information.
