Product Details

The ADBT1002 is a flexible, feature rich digital controller that targets high volume battery testing and formation manufacturing and precision battery test instrumentation applications. The ADBT1002 is optimized for minimal component count, maximum flexibility, and minimum design time. Features include differential remote voltage sense, current sense, pulse-width modulation (PWM) generation, frequency synchronization, overvoltage protection (OVP), and current sharing. Programmable protection features include overcurrent protection (OCP), OVP limiting, and external overtemperature protection (OTP).

Parameters can be programmed over the serial peripheral interface (SPI), providing extensive programming of the integrated loop filter, PWM signal timing, and soft start timing. The SPI provides access to the many monitoring and system test functions. Reliability is improved through a built-in checksum and programmable protection circuits.

A comprehensive graphical user interface (GUI) is provided for simple system and channel configuration and programming of the safety features. The ADBT1002 is available in a 100-lead LQFP_EP.

APPLICATIONS

  • Battery formation and testing
  • High efficiency battery test systems with recycle capability
  • Battery conditioning (charging and discharging) systems
