This datasheet details the Analog Devices ADBT1002, a flexible digital controller for battery formation and testing featuring precise voltage/current…
The ADBT1002 is a feature-rich digital controller optimized for high-volume battery testing, formation manufacturing, and precision test instrumentation. It integrates an analog front end with differential remote voltage sense, current sense, pulse-width modulation (PWM) generation, frequency synchronization, overvoltage protection, and interchip digital current sharing.
Parameters are programmable via a Serial Peripheral Interface (SPI), allowing extensive configuration of integrated loop filters, PWM timing, and soft-start functions. The device supports constant current and constant voltage operating modes with 15-bit setpoint resolution and includes comprehensive monitoring and system test capabilities.
