SGM41298 1.5A Thermoelectric Cooler (TEC) Driver
GENERAL DESCRIPTION
The SGM41298 is a monolithic thermoelectric cooling (TEC) thermostat driver device with two-stage feedback amplifier. The device includes a differential driver (output) stage, an internal 2.5V output reference voltage and two zero-drift, rail-to-rail chopper amplifiers. The first chopper amplifier biases the sensed temperature signal and another is an error amplifier for pensating the closed loop temperature control. This amplifier can be used with a digital controller as well.
The TEC is driven differentially between a linear push-pull stage and a pulse-width modulation (PWM) switching stage. A linear push-pull stage...
