Flexible Temperature, Voltage Monitor, and System Fan Controller

The ADT7462 is a flexible systems monitor IC, suitable for use in a wide variety of applications. It can monitor temperature in up to three remote locations, as well as its ambient temperature.

There are up to four PWM outputs. These can be used to control the speed of a cooling fan by varying the duty cycle of the PWM drive signal applied to the fan. The ADT7462 supports high frequency PWM for 4?wire fans and low frequency PWM for 2?wire and 3?wire fans. Up to eight TACH inputs can be used to measure the speed of 3?wire and 4?wire fans. There are up to 13 voltage monitoring inputs, ranging from 12 V to 0.9 V.
