Abstract

See full text

Circuitry and techniques described herein can use a clamp circuit to provide back-drive compensation in applications where a thermoelectric cooler (TEC) device is to be controlled. A back-drive compensation circuit can be used to inhibit or prevent a linear output stage of a TEC control circuit from being forced out of its intended operating range. The clamp circuit can be implemented using a variety of circuit topologies, such as including a comparator arrangement with hysteresis. In another approach, a linear amplifier topology can provide clamping behavior, such as by injecting or sinking a current at the output node or an intermediate node to inhibit or prevent the output node or intermediate node from being driven outside a specified voltage range by an external source.
