Working Principles

The UCC27201DG4 is a high-speed, high-current low-side gate driver IC. It is designed to efficiently drive power MOSFETs and IGBTs in various applications such as motor drives, power supplies, and inverters. The device operates by receiving input signals from a controller or microcontroller and generating high-current output signals to drive the gate of the power device.

The integrated bootstrap diode simplifies the circuit design by eliminating the need for an external diode. The adaptive shoot-through protection prevents both high-side and low-side MOSFETs from conducting simultaneously, avoiding damaging current spikes. The UVLO protection ensures that the gate driver operates within the specified voltage range, protecting it from potential damage due to overvoltage or undervoltage conditions. The overcurrent protection feature safeguards against excessive current flow, preventing damage to the driver and the power devices.
