GENERAL DESCRIPTION
The ADN8831 is a monolithic TEC controller. It has two inte-
grated, zero drift, rail-to-rail comparators, and a PWM driver.
A unique PWM driver works with an analog driver to control
external selected MOSFETs in an H-bridge. By sensing the
thermal detector feedback from the TEC, the ADN8831 can
drive a TEC to settle the programmable temperature of a laser
diode or a passive component attached to the TEC module.
The ADN8831 supports NTC thermistors or positive tempera-
ture coefficient (PTC) RTDs. The target temperature is set as an
analog voltage input either from a DAC or from an external
resistor divider driven by a reference voltage source.
A proportional integral differential (PID) compensation
network helps to quickly and accurately stabilize the ADN8831
thermal control loop. An adjustable PID compensation network
example is described in the AN-695 Application Note , Using the
ADN8831 TEC Controller Evaluation Board . A typical reference
voltage of 2.5 V is available from the ADN8831 for thermistor
temperature sensing or for TEC voltage/current measuring and
limiting in both cooling and heating modes.
