•
IC101 is high power MOSFET drive with
independent high and low side reference output
channels.
• The power supply for the high channel drive is
floated.
• The bootstrap voltage from VS to VB through
0.33uF capacitor C1122.
• This causes DC level at pin2-VB to be always
approximately 11v higher than pin 4-VS.
• The UV (under voltage) detector is built in the IC, if
the power supply voltage drops below the threshold
level (about 7.5-8.3 v), The IC stops output.
• If IC101 was shorted, sometimes peripheral
resistors are burnt out also.
