ADBT1001BSWZ

ADBT1001 is a flexible, rich digital controller that targets high-volume battery testing, formation manufacturing, and precision battery test instrumentation applications. This is optimized for minimal component count, maximum flexibility, and minimum design time. Features include differential remote voltage sense, current sense, pulse-width modulation generation, frequency synchronization, overvoltage protection, and current sharing. Programmable protection features include overcurrent protection, OVP limiting, and external overtemperature protection. Parameters can be programmed over the serial peripheral interface, providing extensive programming of the integrated loop filter, PWM signal timing, and soft start timing. The SPI provides access to many monitoring and system test functions. Application includes battery formation and testing, high-efficiency battery test systems with recycle capability, battery conditioning systems.
