Notes:
1. VRSM is the maximum voltage drop across the current sense resistor.
2. Analog inputs used as digital inputs can tolerate the same voltage limits as the corresponding analog pad.
There is no reliability concern on digital inputs as long as VIND does not exceed these limits.
3. VIND is limited to VCC33A + 0.2 to allow reaching 10 MHz input frequency.
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 on the pad.
