LO: Low-side Gate Drive Output
The driver is capable of 0.3A source and 0.9A sink peak current to drive the lower MOSFET of the half-bridge leg.
The pin is actively pulled to GND during UVLO.
VS: High Side Gate Return/Current Sense
This is the floating supply return. This pin also acts as a high voltage current sense pin and uses the low-side
MOSFET R
HO: High-side Gate Drive
The driver is capable of 0.3A source and 0.9A sink peak current to drive the high-side MOSFET in the half-bridge. A
resistor internally connected to pin VS ensures that the pin is not floating during UVLO.
VB: High Side floating supply voltage
The bootstrap capacitor connected between this pin and VS is charged by the bootstrap diode when the low-side
gate-drive is high.
