3.6. Characteristics

at TJ = −40 °C to +170 °C, VDD = 4.5 V to 14 V, after programming and locking of the device,

at Recommended Operation Conditions if not otherwise specified in the column “Conditions”.

Typical Characteristics for TJ = 25 °C and VDD = 5 V.

All voltages listed are referenced to ground (GND).

1) if the Hall IC is programmed suitably

2) if more than 50% of the selected magnetic field range are used and the Hall IC is programmed suitably

3) The output signal is updated at the begin of each PWM period or Biphase-M period.

The update time depends on the output format settings.
