Description
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.
Applications
- Driver for N-Channel MOSFETs in High Side Configurations that Control Ground Referenced Loads
- Drives Solenoids, Motors, Relays and Lamps in Automotive Applications
