GENERAL DESCRIPTION
The recommended VCC operating voltage is 10V to 20V for power components. The logic inputs are compatible with standard CMOS or TTL down to 3.3V for easy interfacing control units such as microcontrollers or DSP. The device also integrates two internal protection functions: VCC Power Supply Input Under Voltage Lock-Out and Bootstrap Output Under Voltage Lock-Out.
