ADBT1002BSWZ

Overview

The ADBT1002 is a four-channel analog front end (AFE) and digital controller designed for battery formation and testing. It integrates precision current and voltage sensing with 12-bit ADCs, a programmable PID digital controller, and 14-bit PWM generation. The device supports switching frequencies from 62.5 kHz to 500 kHz and features interchip synchronization and current sharing. Key specifications include a 40 V/V current sense gain, 0.5 V/V voltage sense gain, and an internal 2.5 V reference. It operates within a 0°C to 85°C range and communicates via SPI.

Feature Summary

• Four independent channels with integrated AFE, digital PID controller, and 14-bit PWM
• Programmable switching frequency from 62.5 kHz to 500 kHz in powers of two
• Interchip digital current sharing and frequency synchronization for parallel operation
• Supports constant current and constant voltage modes with 15-bit setpoint resolution

Applications

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

Procurement Notes
