PIN I/O DESCRIPTION
NAME NO.
HB 2 I High-side bootstrap supply. The bootstrap diode is on-chip but the external bootstrap capacitor is required. Connect positive side of the bootstrap capacitor to this pin. Typical range of HB bypass capacitor is 0.022μF to 0.1μF, the value is dependant on the gate charge of the high-side MOSFET however.
HI 5 I High-side input.
HO 3 O High-side output. Connect to the gate of the high-side power MOSFET.
HS 4 I High-side source connection. Connect to source of high-side power MOSFET. Connect negative side of bootstrap capacitor to this pin.
LI 6 I Low-side input.
LO 8 O Low-side output. Connect to the gate of the low-side power MOSFET.
VDD 1 I Positive supply to the lower gate driver. Decouple this pin to VSS (GND). Typical decoupling capacitor range is 0.22μF to 1μF.
VSS 7 O Negative supply terminal for the device which is generally grounded.
PowerPAD PAD — Used on the DDA and DRM packages only. Electrically referenced to VSS (GND)(1). Connect to a large thermal mass trace or GND plane to dramatically improve thermal performance.
(1) The thermal pad is not directly connected to any leads of the package; however, it is electrically and thermally connected to the substrate which is the ground of the device.
