Product Summary
The HIP4081AIBZ is a Three Phase Bridge N-Channel MOSFET driver IC. The HIP4081AIBZ is specifically targeted for PWM motor control. It makes bridge based designs simple and flexible. It has a flexible input protocol for driving every possible switch combination. The device is suitable for applications requiring DC to 100kHz. Unlike the previous family members, the HIP4081AIBZ has a programmable undervoltage set point. The applications of it are Brushless Motors, AC Motor Drives, Switched Reluctance Motor Drives, Battery Powered Vehicles.
