Working Principles

HIP4081AIPZ operates by receiving input control signals (IN1 to IN4) and generating corresponding high-side (HO1 to HO4) and low-side (LO1 to LO4) outputs. These outputs drive external power MOSFETs, enabling bidirectional power flow in a full-bridge configuration. The integrated bootstrap diode simplifies the circuit design by providing the necessary voltage for driving the high-side MOSFETs. Shoot-through protection ensures that both high-side and low-side MOSFETs are not simultaneously turned on, preventing short circuits and improving overall system reliability.
