ADN8833 - 1A Thermoelectric Cooler (TEC) Driver

General Description

The ADN88331 is a monolithic H-bridge TEC driver with integrated 1 A power MOSFETs.

It has a linear power stage with the linear driver (LDR) output and a pulse-width modulation (PWM) power stage with the SW output.

Key Features

  • Patented high efficiency single inductor architecture.
  • Integrated low RDSON MOSFETs for TEC driver.
  • TEC voltage and current operation monitoring.
  • No external sense resistor required.
  • Independent TEC heating and cooling current limit settings.
  • Programmable maximum TEC voltage.
  • 2 MHz PWM driver switching frequency.
  • External synchronization.
  • Digital thermal control loop compatible.
  • 2.50 V reference output with 1% accuracy.
  • Available in a 25-ba.
