Working Principles

The MCP14A0303-E/SN is designed to drive power MOSFETs and IGBTs efficiently. It utilizes a bootstrap technique to provide a high-side gate drive voltage. The input control signal (IN) determines the state of the low-side gate driver (LO) and high-side gate driver (HO). When the input signal is high, the LO output is driven low, turning on the low-side switch. Simultaneously, the HO output is driven high, turning off the high-side switch. Conversely, when the input signal is low, the LO output is driven high, turning off the low-side switch, while the HO output is driven low, turning on the high-side switch.
