The MAX1978ETM+T from Analog Devices is a compact and accurate single-chip temperature controller specifically designed for Peltier thermoelectric cooler (TEC) modules. It integrates power FETs and thermal control-loop circuitry, minimizing the need for external components and maintaining high efficiency. The device features selectable 500kHz/1MHz switching frequencies and a unique ripple-cancellation scheme to optimize component size, efficiency, and reduce noise.
This controller provides bipolar ±3A output and maintains an exceptional temperature stability of ±0.001°C. It directly controls output current to prevent surges and offers individual heating and cooling current and voltage limits for robust TEC protection. The MAX1978ETM+T operates from a single 3V to 5.5V supply and is specified for an operating temperature range of -40°C to +85°C.
Designed for applications requiring precise thermal management, such as fiber optic laser modules and WDM/DWDM laser-diode temperature control, the MAX1978ETM+T is housed in a low-profile 48-lead TQFN (7x7) package with an exposed pad for enhanced thermal performance. Its small circuit footprint and height make it suitable for space-constrained designs.
