Temperature Monitor Using Analog Pad AT
Notes:
1. V
2. Analog inputs used as digital inputs can tolerate the same voltage limits as the corresponding analog pad. There is no reliability
3. V
4. Measurement is done by forcing a temperature on an external diode, with the Fusion device at room temperature.
5. The temperature offset is a fixed positive value.
6. The high current mode has a maximum power limit of 20 mW. Appropriate current limit resistors must be used, based on voltage
