Notes
1. The current is specified without commutation of the bridge. The current into pin HV is limited by a thermal protection
circuit. The current is limited to 11 mA at Tj = 150 °C.
2. The current is specified without commutation of the bridge and pin HV is connected to VDD.
3. The minimum frequency is mainly determined by the value of the bootstrap capacitors.
