ICL7667EPA is a type of Pragmatic Power Interface Controller (PMIC) gate driver. This gate driver is designed to provide current sources and sinks, guaranteeing efficient and accurate drive circuits for very large power Mosfets in high current power management applications. In this article, we will explore the application field and working principle of ICL7667EPA.
Application Field
ICL7667EPA is widely used in very large power Mosfet high-current power management applications. It features an integrated gate driver circuit, providing current sources and sinks paired with wide adjustable drive range. In addition, you can program through an external resistor the rated gate drive current and drive level. ICL7667EPA is particularly suitable for applications such as: industrial automation and robotics, medical equipment and monitoring systems, power supplies, automotive power control, lighting and display control and a variety of other applications.Functionality
The ICL7667EPA gate driver is designed to provide enhanced efficient, fast and accurate drive circuit for power Mosfets. It gives you a fast response time between power supply turn-on and the Mosfets turning on. This saves time and increases efficiency. The ICL7667EPA is configured to work with a single power supply. Its logic inputs are compatible with 3V and 5V logic interfaces, receiving 0V logic input. The gate output provides a wide adjustable range of gate drive to the MOSFETs.Features
ICL7667EPA features a wide 5V/ 15V input voltage range and an integrated charge pump providing drive voltages up to 15V. It also has thermal protection and is designed to withstand over-current, reverse bias, and electrostatic discharge damage. The ICL7667EPA also has many other helpful features such as programmable turn-on time, over-voltage protection, adjustable gate drive current and over-current shutdown. The integrated output current sink and source support a wide adjustable range of low side and high side logic levels, ensuring proper gate drive to the MOSFETs over the entire operating voltage range.Pin Configurations
The ICL7667EPA features a 28-pin TSSOP configuration and 5 pins to the output buffer. The 5 pins on the buffer are I1 and I2 (input pins of the output buffers), D1 and D2 (output pins of the output buffers) and PDRV (Power supply for the output buffer). The input pins are named EN, VIN, VCCI, RD1 and RD2. EN and VIN are used to control the current sink and source of the outputs. VCCI is the power supply pin of the input buffer, while the RD1 and RD2 are used to program the gate drive current.Working Principle
The ICL7667EPA is designed to provide current sinks and sources, guaranteeing efficient and accurate drive circuits for very large power Mosfets in high current power management applications. It features an integrated gate driver circuit, providing current sources and sinks paired with a wide adjustable drive range. When the EN pin is set to low, the VIN and VCCI pins will apply a positive voltage to the gate-source terminal of the Mosfet, turning it on. When the EN pin is set to high, the VIN pin will provide a positive voltage to the source terminal, whereas the VCCI pin will apply a negative voltage, turning off the Mosfet. The RD1 and RD2 pins are used to program the gate drive current. The value of the source or sink current is determined by: i = (Vdd – Vi)/Ri Where Vdd is the power supply voltage, Vi is the voltage across the input pins and Ri is the value of the external resistor. In addition, the ICL7667EPA has many other helpful features such as programmable turn-on time, over-voltage protection, adjustable gate drive current and over-current shutdown.Conclusion
In conclusion, ICL7667EPA is a powerful Pragmatic Power Interface Controller (PMIC) gate driver that is designed to provide current sources and sinks, guaranteeing efficient and accurate drive circuits for very large power Mosfets in high current power management applications. It features an integrated gate driver circuit, providing current sources and sinks paired with a wide adjustable range of drive levels. It has many helpful features such as programmable turn-on time, over-voltage protection, adjustable gate drive current and over-current shutdown.The specific data is subject to PDF, and the above content is for reference
