Мікросхема ISL6801AB

High Voltage Bootstra

p High Side Driver

The ISL6801 is a single monol

ithic, inverting bootstrap

driver. Its floating Level Shifte

r Section is optimized for the

control of N-Channel Power MOSFETs in high side

configurations with Bus Voltage

s up to 120VDC from a 5V

Controller Output. It features two output stages pinned out

separately to allow independent control of rise and fall times.

To ensure static DC operatio

n an integrated recharge path

charges the bootstrap cap while

the driver is switched off. A

pull-up resistor forces the input low when no control signal is

applied. The supply voltage is monitored to guarantee

faultless operation at start-up.
