Working Principles

The IRS2001MPBF is an isolated gate driver that utilizes galvanic isolation to separate the control circuitry from the power devices. It operates by receiving input signals on the IN pin, which are then amplified and transmitted to the high-side and low-side outputs (HO and LO) respectively. The galvanic isolation ensures that any potential differences or noise on the power side do not affect the control side, providing a safe and reliable interface.
