GENERAL DESCRIPTION
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...
