thermoelectric cooler (TEC) or heater applications requir-ing either unidirectional or bidirectional drive circuits. All of the necessary control circuitry and two sets of comple-mentary output drivers are integrated into the LTC1923 to drive a full bridge, providing an efficient means of bidirec-tional current flow to the TEC. An accurate ...
