TI AMC80AIPWR

The AMC80 is a system hardware monitoring and control circuit featuring a seven-channel 10-bit ADC, two programmable fan speed monitors, and a two-wire interface. The AMC80 also provides programmable upper and lower limit alarm functionality. The alarm is triggered when the programmed limit is exceeded.

The AMC80 is compatible with both linear and digital temperature sensors. With a 2.5mV LSB and a 2.56V input range, the device accepts input from linear sensors such as the TMP20. The BT pin serves as the input for digital sensors such as the TMP75. The AMC80 operates from a supply voltage of 3V to 5.5V, and its low supply current combined with two-wire interface configurability make it well-suited for integrated motor driver solutions.

The AMC80 is available in a 24-pin TSSOP package and is fully rated for operation over a temperature range of -40°C to +125°C.
