Pin Functions

PIN I/O DESCRIPTION
NAME NO.
COM 5 – Return for low-side driver output.
EN/NC 4 I Enable input for high-side and low-side driver. This pin biased LOW, disables both HO and LO regardless of HI and LI state, This pin biased high or floating enables both HO and LO.
HB 13 I High-side floating supply. Bypass this pin to HS with a suitable capacitor to sustain boot-strap circuit operation in the desired application, typically 10× bigger than gate capacitance.
HI 1 I Logic input for high-side driver. If HI is unbiased or floating, HO is held low.
HO 12 O High-side driver output.
HS 11 – Return for high-side floating supply.
LI 2 I Logic input for low-side driver. If LI is unbiased or floating, LO is held low.
LO 6 O Low-side driver output.
NC 8, 9, 10, 14 – No connection.
VDD 7 I Bias supply input. Power supply for the input logic side of the device and also low-side driver output. Bypass this pin to VSS with typical 1-µF SMD capacitor (typically CVDD needs to be 10 × CBOOT). If shunt resistor used between COM and VSS, then also bypass this pin to COM with 1-µF SMD capacitor.
VSS 3 – Logic ground.
