MCP14628-E/MF

Power management integrated circuits (PMIC) have been at the forefront of modern power system design for decades. One of the most common type of PMICs are gate drivers, which are integrated circuits that drive the gates of power transistors, controlling the flow of current in the transistor\'s circuit. The MCP14628-E/MF is one such gate driver. This article will discuss the application field and working principle of the MCP14628-E/MF.

Applications

The MCP14628-E/MF is a high current gate driver designed to operate in harsh environments and at temperatures of up to 125°C. It is capable of driving high power BJTs, MOSFETs, and IGBTs, and is used in a variety of applications such as automotive safety systems, power supplies, LED lighting, and motor control systems. It is available in a wide range of packages, from small overmolded SOPs to large DIL packages, ensuring that it can be used in virtually any system.

Working Principle

The MCP14628-E/MF operates by feeding a low-voltage digital signal into the MOSFET gate through the gate driver\'s transistor. When the signal is high, the transistor is open allowing current to flow to the gate. This causes the MOSFET to turn on, allowing current to flow through the circuit. When the signal is low, the transistor is closed, preventing current from flowing to the gate of the MOSFET. This causes the MOSFET to turn off, preventing current from flowing through the circuit.

The MCP14628-E/MF also features 35V ESD protection to protect against voltage spikes, and over-temperature protection which will automatically shut off the device in the event of excessive heat. Additionally, the MCP14628-E/MF includes a wide range of integrated safety features, including over-voltage and under-voltage protection.

Conclusion

The MCP14628-E/MF is a highly robust gate driver designed to operate in harsh conditions and temperatures of up to 125°C. It is capable of driving high power BJTs, MOSFETs, and IGBTs, and is used in a variety of applications such as automotive safety systems, power supplies, LED lighting, and motor control systems. It includes a range of integrated safety features, including over-voltage and under-voltage protection, as well as 35V ESD protection and over-temperature protection.
