The MAX1969EUI+ is a power driver for Peltier TEC module in 28 pin TSSOP package. It is a highly integrated and cost effective, high-efficiency, switch-mode drivers for Peltier thermoelectric cooler (TEC) modules. The device utilizes direct current control to eliminate current surges in the TEC. On-chip FETs minimize external components while providing high efficiency. A 500KHz/1MHz switching frequency and a unique ripple cancellation scheme reduce component size and noise. The MAX1969 provides unipolar output up to 6A. Reliability is optimized with settable limits for both TEC voltage and current with independently set limits for heating and cooling current. An analogue output also monitors TEC current. Typical applications include fibre optic laser modules, WDM, DWDM laser diode temperature control, fibre optic network equipment, EDFA optical amplifiers, telecom fibre interfaces, ATE and biotech lab equipment.
