The TC429MJA is a member of PMIC Gate Drivers family. It is designed to provide a low on-resistance to lead the way of high frequency switching with low voltage. The TC429MJA supports a wide supply voltage range and features low output impedance, low propagation delays and low leakages. The TC429MJA is a gate driver suitable for various applications including switch-mode power supplies, MOSFET, IGBT and power transistor gate control.

Introduction

The TC429MJA is an integrated gate driver from Torex Semiconductor. It was specially designed for switch-mode power supplies, motor speed control and motor power supplies. It is a 4-channel integrated gate driver for high frequency, low voltage operations. It offers a broad supply voltage range from 4.5V to 18V, allowing it to operate from single or dual supply systems. The low output impedance of the TC429MJA can support up to 900mA of load current. The TC429MJA also provides fast response times, low propagation delays and low junction leakage current. It is suitable for driving MOSFET, IGBT and power transistor gates.

Operating Principle

When the gate driver is powered, it turns on its internal switch that connects the lower power supply. The input of the TC429MJA is a logic control signal, which has to meet the logic-compatible logic level. Then, it either turns on the connection between the lower power supply with the GND (ground) or keep it disconnected. The power input to the gate driver is usually supplied as VDDH, so a large voltage difference is formed between VDDH and the load which controls the power switch. Then, the internal switch on the TC429MJA is opened or closed depending on the input logic control signal. In addition, the TC429MJA also has an internal clamp circuit which ensures that the output voltage does not exceed the VDDH.

Applications

The TC429MJA is suitable for various applications within the switch-mode power supplies and motor speed control. It can be used to control the power supplied to DC motors, AC motors and brushless DC (BLDC) motors. The TC429MJA provides a low on-resistance and a fast response time for controlling the speed and torque of a motor. The TC429MJA also has a low output impedance that can support heavy loads. It can be used in low-voltage switching applications such as LED lighting, solar panel systems and consumer electronics.

The Torex TC429MJA gate driver can also be used in industrial systems. It can be used to control the on/off switching of HVAC systems, air conditioning systems, pumps and for other industrial systems. The low output impedance and low propagation delay of the TC429MJA can ensure smooth and efficient control of power switching.

The TC429MJA is also suitable for use in automotive systems. It can be used to control the power electronics of electric and hybrid vehicle systems such as the electric drivetrain, power steering, air suspension and other automotive systems. The low output impedance, fast response time and low propagation delay of the TC429MJA ensure that the power electronics are efficiently controlled.
