The TC4426AVMF713 is a PMIC - Gate Drivers designed to provide high peak pulse current up to 600mA and drive loads up to 100V. It is fully compatible with standard gate drive transformers without any additional components. The TC4426AVMF713 offers a wide range of features that make it an ideal solution for applications requiring high performance and reliability.

The TC4426AVMF713 offers a wide range of protection features such as over-voltage protection with a 10-20V range, thermal protection and over-current protection with a 0.5A/1.2A switch. The TC4426AVMF713 also provides soft-start, under volt-lockout, frequency control and pulse-by-pulse current limiting to prevent device damage and improve system reliability.

In terms of its applications, the TC4426AVMF713 is most commonly used to drive loads such as motors, lights, and valves in industrial, robotics, medical and commercial sectors. It is also used in automotive powertrain and braking systems. Other applications include high current PWM applications such as power conversion, switched mode power supplies and LED lighting.

The TC4426AVMF713 is usually operated in non-inverting mode and works with a maximum frequency of 400kHz. The device consists of a high-side MOSFET with integrated In-package Bootstrap diode, as well as an adjustable dead-time control, current sense input and bias voltage supply. The output is protected by a integrated Over-Current Protection (OCP) and thermal shutdown circuit.

The TC4426AVMF713 uses a bootstrap circuit to generate the gate voltage needed to operate the high-side MOSFET. The bootstrap circuit comprises two capacitors connected to the switching node of the high side MOSFET. When the high side MOSFET is driven in the off state, a voltage is generated across the two capacitors which can be used to provide the gate voltage for the high side MOSFET. The TC4426AVMF713 also features a programmable dead-time control circuit that adjusts the dead-time for switching cycles based on the load and operating conditions.

The TC4426AVMF713 also features an adjustable OCP feature which can be set at 0.5A to 1.2A to protect the device from over-current conditions. It also provides an under-voltage lockout with a 10-20V range to prevent accidental device damage when the power supply is too low. The device also provides a frequency control feature that allows the switching frequency to be controlled to avoid mechanical noise and EMI problems.

The TC4426AVMF713 is a versatile PMIC - Gate Drivers that offers superior performance and reliability. It is widely used in various industrial, robotics, medical and commercial sectors, as well as in automotive powertrain and braking systems and high current PWM applications. The device also provides a wide range of features such as over-voltage and over-current protection, under-voltage lockout and frequency control, making it a great choice for applications requiring high performance and reliability.
