TC4420VMF713 Application Field and Working PrincipleTC4420VMF713 is an integrated dual full bridge gate driver, designed to drive N-channel power MOSFETs and IGBTs. It can be used in various dc-dc conversion and motor control applications. This document explains the application field of the TC4420VMF713 and the chip\'s working principle.Application FieldThe TC4420VMF713 is a dedicated MCU-compatible gate driver that can drive two independent full bridges. It can be used in various DC-DC conversion and motor control applications.In DC-DC conversion, the TC4420VMF713 can be utilized in a variety of switching power supplies, such as flyback, buck, and boost converters. For motor control, it can be used in brushed DC (PMDC), brushless DC (BLDC), and permanent magnet synchronous motors (PMSM).Working PrincipleThe TC4420VMF713 operates with two independent channels. Each channel has a high-side and low-side output and a power loss detector. The high-side and low-side outputs are designed to drive either N-channel MOSFETs or IGBTs.The high-side output is driven by an internal charge pump that boosts the input voltage, allowing the output voltage to be higher than the input voltage. The low-side output can be used to switch the power transistor directly, or it can be used in combination with a register, allowing the user to programmatically set the output voltage.The chip\'s power loss detector monitors the channel\'s current and shuts down the channel if the current in either the high-side or low-side transistor exceeds a preset value. The user can program the over current threshold value via the internal registers.The TC4420VMF713 also features a thermal shutdown circuit that shuts down the chip if the chip\'s temperature exceeds a preset threshold. This feature helps protect the chip from damage due to excessive heat.ConclusionThe TC4420VMF713 is a MCU-compatible dual full-bridge gate driver. It can be used in various DC-DC conversion and motor control applications. The chip features high side and low side output drivers, a power loss detector, and a thermal shutdown circuit. These features have enabled the chip to be a reliable and robust solution for driving N-channel MOSFETs and IGBTs.
