ADN8835ACPZ-R2

Power Management - Specialized Overview

The ADN8835ACPZ-R2 is an ultracompact 3 A thermoelectric cooler (TEC) controller from Analog Devices, housed in a 36-pin, 6 mm x 6 mm LFCSP package. It integrates a linear power stage and a PWM power stage operating at a typical 2.0 MHz frequency with external synchronization capability. The device features integrated low RDS(ON) MOSFETs for efficient H-bridge control without external sense resistors. It includes two zero-offset, rail-to-rail chopper amplifiers for precise PID compensation and supports NTC or RTD thermal sensors. A 2.50 V, 1% precision reference voltage biases the sensor networks, while independent heating and cooling current limits ensure safe operation.
