The TC4427AEMF713 is an advanced Gate Driver for automotive MOSFETs and IGBTs. With its low on-resistance and high current capability, it is well-suited for driving loads in automotive, industrial, and consumer applications. This versatile application-field driver has been designed to cover a wide range of applications, from high-power motor control applications to higher frequency switching devices and low-side/high-side current sensing applications.

The TC4427AEMF713 offers a robust power stage which is able to drive large loads and supports dual outputs, one on each side of the package. It offers a selectable small and large switching frequency, allowing for high-frequency switching and current limiting at higher frequencies. Additionally, it provides enable inputs to support multiple output channels, feature enable/disable logic, and adjust the gate drive current.

In a typical application, the TC4427AEMF713 is connected to a power MOSFET or IGBT via the drain and source pins, utilizing the +VBC and VSS pins for power supply. The supply voltage applied to the Vcc pin provides the high voltage turn-on and low voltage turn-off of the MOSFET/IGBT. The Gate pin is the primary control pin for controlling the on/off state of the MOSFET/IGBT.

The TC4427AEMF713 operates with a constant voltage control, where the voltage applied to the Gate pin determines the MOSFET/IGBT switching state. The Gate pin voltage can also be adjusted by the enable input to activate and deactivate switching.

The TC4427AEMF713 features a wide input voltage range of up to 40V, pulsed output current capability of up to 30A, rise and fall times adjustable between 1ns and 5ms, slew rate adjustable between 0.1V/ns and 2.5V/ns, adjustable maximum ON/OFF times, and adjustable operational modes. This ensures a high level of flexibility for the user.

The TC4427AEMF713 is also available in a programmable version, capable of providing adjustable gate drive current and/or control signals. In this version, the user can adjust the gate drive current and setting times of the device by connecting a few pins to the microcontroller. This allows for more precise current control and minimal power consumption.

The TC4427AEMF713 is a high-performance integrated Gate Driver for automotive MOSFETs and IGBTs, offering a wide range of features and advantages for a variety of applications. The device is well suited for automotive, industrial, and consumer applications and provides a robust power stage for driving large loads, as well as adjustable switching frequency, control logic and maximum ON/OFF times. The programmable version offers even more flexibility and control, allowing the user to adjust the gate drive current and setting times easily.
