Phase A High-Side Driver Return. Connect to the bootstrap capacitor
and to a resistor that connect to the source of the external MOSFET.
See the Applications section for additional information on the resistor.
Phase A High Side Drive Output. Connect to the gate of the external
high-side power MOSFET.
Phase A High-Side Bootstrap Supply. An external bootstrap capacitor
is required. Connect the bootstrap capacitor across this pin and A_HS.
An on-board bootstrap diode is connected from V_DD to A_HB.
Input Supply for Gate Drivers and Internal Logic/Control Circuitry.
Decouple this pin to V_SS with a minimum 2.2 μF ceramic capacitor.
Fault Delay. Connect an external capacitor from this pin to ground to
increase the current-limit reset delay. Leave open for minimum delay.
Do not externally drive this pin.
Phase C Power and Control Circuitry Ground.
Phase C Low-Side Drive Output. Connect to the gate of the low-side
power MOSFET gate.
Phase C High-Side Driver Return. Connect to the bootstrap capacitor
and to a resistor that connect to the source of the external MOSFET.
See the Applications section for additional information on the resistor.
Phase C High-Side Drive Output. Connect to the gate of the external
high-side power MOSFET.
Phase C High-Side Bootstrap Supply. An external bootstrap capacitor
is required. Connect the bootstrap capacitor across this pin and C_HS.
An on-board bootstrap diode is connected from V_DD to C_HB.
No Connect.
