2Supply voltage, VCC, is defined as the voltage drop between pin 1 and pin 4 of the device. It does not include the voltage drop across RSENS.
3ICC ratio is defined as ICC(HIGH) / ICC(LOW) for a given PWM cycle.
4See Characteristic Definitions section.
5fC varies up to approximately ±20% over the full operating ambient temperature range, TA, and process.
6Clamp duty cycles are tested with the maximum sensitivity code addressed and an applied magnetic field that is at least 25% greater than
the dynamic range.
7Jitter is dependent on the sensitivity of the device. Values are based on characterization only and are not guaranteed via production testing.
