LTC1325 Microprocessor-Controlled Battery Management System FEATURES s s DESCRIPTION The LTC®1325 provides the core of a flexible, cost-effective solution for an integrated battery management system. The monolithic CMOS chip controls the fast charging of nickel-cadmium, nickel-metal-hydride, lead-acid or lithium batteries under microprocessor control. The device features a programmable 111kHz PWM constant current source controller with built-in FET driver, 10-bit ADC, internal voltage regulator, discharge-before-charge controller, programmable battery voltage attenuator and an easy-to-use serial interface. The chip may operate in one of five modes: power shutdown, idle, discharge, charge or gas gauge.
