Electrical characteristics

All voltages referred to ground (SGNDx ground) and currents are assumed to be positive

when current flows into the pin.

3.5.1

Supply

The device is operated in the specified operating range, unless otherwise specified



(VCC = 3.20 V to 5.25 V, VB = 4.2 V to 54 V, Tj = -40 °C to 150 °C).
