21 The MAX31760 integrates temperature sensing along with precision PWM fan
23 temperature of a discrete diode-connected transistor, such as a 2N3906,
27 I2C-compatible interface. Fan speed is controlled based on the temperature
28 reading as an index to a 48-byte lookup table (LUT) containing
29 user-programmed PWM values. The flexible LUT-based architecture enables
30 the user to program a smooth nonlinear fan speed vs. temperature transfer
31 function to minimize acoustic fan noise. Two tachometer inputs allow
35 remote high-temperature threshold has been exceeded.
37 Temperature measurement range: from -55°C to 125°C
