The MAX6639AEE+ is a new type of integrated circuit package produced by Maxim Integrated. It is part of the Power Management and Interface IC family, Thermal Management segment. It is designed for use in thermoelectric cooling (TEC) applications. Its features include an adjustable output current limit, temperature measurement, fan-speed control and a PWM (pulse width modulation) driver. This makes it an ideal choice for a wide range of LED lighting applications.

The core of the MAX6639AEE+ is a pre-configured analog output module that can be used to control the fan speed, voltage, and current accurately and reliably. The output is feedback-controlled, allowing it to handle a very wide range of variables and to deliver consistent performance. In addition to temperature control and fan speed control, the MAX6639AEE+ also has a digital output module. This digital output module has a programmable output waveform that is configurable in both amplitude and frequency. This is used to provide a PWM (pulse width modulation) signal, allowing the MAX6639AEE+ to control other parameters in an electronic device, such as a power supply voltage.

The MAX6639AEE+ has a versatile temperature monitoring feature. It comprises of an analog-to-digital converter, which converts a temperature signal from an external thermistor into a digital temperature value. The module also incorporates a temperature hysteresis control block to limit the temperature swing. This feature helps to reduce temperature cycling and enables more accurate temperature control. The module is rated for a range of -20 to 125 C.

The MAX6639AEE+ also provides a basic fan speed control functionality. The output current is adjustable, allowing the device to control a wide range of fan speeds. The output current limit is programmable, allowing the user to optimize the fan speed for the particular application. The fan speed can also be monitored, with the duty cycle and frequency generated by the module reported back by an A/D converter.

The MAX6639AEE+ is a highly reliable and cost-effective solution for TEC applications. It is designed to deliver accurate temperature measurements and fan speed control, and to provide protection for the device it is installed in. Additionally, its configurable PWM output allows it to be used as a driver for a range of applications. This makes the MAX6639AEE+ an ideal choice for LED lighting and other thermal management applications.
