Pin Name
Pin Function
Positive Supply to lower gate drivers. Decouple this pin to VSS (Pin 7). Bootstrap
diode connected to HB (pin 2).
High-Side Bootstrap supply. External bootstrap capacitor is required. Connect
positive side of bootstrap capacitor to this pin. Bootstrap diode is on-chip.
High-Side Output. Connect to gate of High-Side power MOSFET.
High-Side Source connection. Connect to source of High-Side power MOSFET.
Connect negative side of bootstrap capacitor to this pin.
Control Input. PWM high signal makes high-side HO output high, and low-side
LO output low. PWM low signal makes high-side HO output low, and low-side
LO output high.
Low-Side Disable. When pulled low, this control signal immediately terminates
the low-side LO output drive. The low-side LO output drive will remain low until
this signal is removed. HS drive is not affected by the LS signal. Here is the
logic table:
