The MAX1968EUI by Analog Devices Inc. is a switch-mode power driver designed for Peltier thermoelectric cooler (TEC) modules. It offers direct current control to prevent current surges in the TEC and utilizes on-chip FETs for high efficiency.
This device provides bipolar output current up to ±3A, enabling precise temperature control without dead zones or nonlinearities at low load currents. It operates with a switching frequency of 500kHz or 1MHz, contributing to reduced component size and noise. The MAX1968EUI features a 1% accurate voltage reference and is specified for operation over the -40°C to +85°C temperature range.
Applications for the MAX1968EUI include temperature control for fiber optic laser modules, WDM/DWDM laser diodes, EDFA optical amplifiers, and biotech lab equipment. It is housed in a thermally enhanced 28-pin TSSOP-EP package with an exposed metal pad to minimize operating junction temperature.
The device allows for settable limits for TEC voltage and current, with independently adjustable heating and cooling current limits. An analog output is available to monitor TEC current, providing valuable feedback for system performance optimization.
