SETTING THE BOOTSTRAP CAPACITOR
When a bootstrap capacitor is connected, it raises the output-ON voltage (at the OUT pin (pin 15) when the
external MOS FET is turned “ON”) to the V
CC
2 level. It can therefore drive the MOS FET at a higher threshold
voltage (V
th
).
Connecting the bootstrap capacitor
1.
Connect the bootstrap capacitor between the CB pin (pin 13) and OUT pin (pin 15).
