This application note describes the 16HV785 Programmable Lead Acid Battery Charger, which provides an unprecedented level of configurability for charging lead battery packs. The 16HV785's precise, 10-bit Analog-to-Digital converter and high-frequency Pulse-Width Modulator enable the device to provide optimum control of charging algorithms for lead battery chemistries. The 16HV785 can be configured as either a Switch mode or a linear charger. The paper details the device's features and applications, and provides a reference schematic and a description of the charger's lead chemistry.
