ISL6801
FN9087.2
High Voltage Bootstrap High Side Driver
The ISL6801 is a single monolithic, inverting bootstrap
driver. Its floating Level Shifter Section is optimized for the
control of N-Channel Power MOSFETs in high side
configurations with Bus Voltages 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 operation 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.
