PMIC - Gate Drivers

The NCP81382MNTXG gate driver is an integrated power-management device designed to control and manage output and gates of multiple semiconductor switches in an efficient way.

Application Field

The NCP81382MNTXG gate driver is ideal for use in a variety of applications including:

• Automotive motors, including pumps, compressors, and fans
• Computer power supplies
• White goods and home appliances
• Lighting systems
• Power generation and transmission

In addition, the NCP81382MNTXG is an ideal solution for applications where high-efficiency power management is critical, such as hybrid and electric vehicles, power-over-Ethernet applications, data centers, and renewable energy systems.

Working Principle

The NCP81382MNTXG enables the efficient control and management of semiconductor switches. This is achieved by supporting synchronous and asynchronous control of the coil currents, actively dampening the dV/dt of both the high-side and low-side drivers, driving the signals with a minimum of dead time, and ensuring reliable gate-turn-on.

The NCP81382MNTXG contains three low-side gate drivers, one high-side gate driver, and a set of protection functions. The low-side drivers are controlled by a separate 22-bit pulse-width modulation (PWM) signal for each one. The high-side driver is controlled by a separate 20-bit PWM signal. Additionally, each low-side and high-side driver can be programmed independently to control both dead time and slew rate. The low-side and high-side drivers are further isolated by internal isolates to ensure reliable and efficient performance.

The NCP81382MNTXG also provides a set of protection functions, including over-temperature protection, over-current protection, and under-voltage lockout. In addition, the NCP81382MNTXG is able to detect faults on the gate drivers and other conditions, providing diagnostic information.

Conclusion

The NCP81382MNTXG is an integrated power-management device designed to control and manage output and gates of multiple semiconductor switches in an efficient way. It is ideal for use in a variety of applications, and supports synchronous, asynchronous, and diagnostic control of the coil currents. Additionally, it provides a set of protection functions, ensuring reliable and efficient performance.
