ILIM The ADN8833 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. Depending on the
control voltage at the CONT input, the ADN8833 drives current
through a TEC to settle the temperature of a laser diode or a passive
component attached to the TEC module to the programmed
target temperature.
The control voltage applied to the CONT input is generated by a
digital-to-analog converter (DAC) closing the digital proportional,
integral, derivative (PID) loop of temperature control system. LDR CONTROLLER
