MAXIM INTEGRATED PRODUCTS MAX1978ETM+T 温度传感器芯片, -40 °C, 85 °C, TQFN, 48 引脚
The is an integrated temperature controller for peltier thermoelectric cooler TEC modules in 48 pin TQFN package. On-chip power FETs and thermal control loop circuitry minimize external components while maintaining high efficiency. Selectable 500KHz/1MHz switching frequency and unique ripple cancellation scheme optimize component size and efficiency while reducing noise. Switching speed of internal MOSFET is optimized to reduce noise and EMI. The MAX1978 operates from single supply and provides bipolar ±3A output by biasing TEC between outputs of two synchronous buck regulators. A chopper stabilized instrumentation amplifier and high precision integrator amplifier are supplied to create a proportional integral PI or proportional integral derivative PID controller. The MAX1978 is used in fibre optic laser modules, WDM, DWDM laser diode temperature control, fibre optic network equipment, EDFA optical amplifiers, ATE and telecom fibre interfaces.
