Working Principles

The MCP1401T-E/OTVAO is a gate driver IC designed to control the switching of MOSFETs. It operates by receiving a control signal at the IN pin, which determines the state of the low-side output (LO) and high-side output (HO) pins. When the control signal is active, the LO pin is driven low, allowing the low-side MOSFET to conduct. Simultaneously, the HO pin is driven high, turning off the high-side MOSFET. Conversely, when the control signal is inactive, the LO pin is driven high, turning off the low-side MOSFET, while the HO pin is driven low, enabling conduction of the high-side MOSFET.
