The NCP81166MNTBG is a high-performance motor driver designed for applications such as brushless motors, compressor motors, and pressure pumps. This device integrates half-bridge drivers using low conduction losses and minimum EMI generation, making it suitable for high-performance motor drives. The NCP81166MNTBG features a PWM thermal protection, which optimizes its performance by constantly monitoring and adjusting its operating parameters in response to its thermal environment. Additionally, the device has a proprietary algorithm for its current control, making it remarkably accurate and robust.

To optimize the performance of NCP81166MNTBG, it includes several advanced features such as integrated current sense resistors, high temperature operation up to 105 ^oC, safety protections such as under-voltage and over-temperature lockout, and integrated charge pump circuitry.

The NCP81166MNTBG is well-suited for driving brushless motors, compressor motors, and pressure pumps, as it provides a wide range of configurations. It has four operational modes, namely toggled, inversion, slow startup, and dual road enable. It also provides integrated current sense resistors for error current sensing and a programmable soft-start for maximum protection of the motor. Furthermore, it has a protection system that prevents excessive motor current.

The NCP81166MNTBG works in two main stages. The first is a pre-drive stage, which is used to turn the motor on and off. In the pre-drive stage, the gate drive signals are generated in a complementary way and the voltage across the load is limited to a maximum peak value. During the second stage, the main drive is used to regulate the speed and torque of the motor. This stage has two components: the slow linear ramp generator, which is used for slow speed control, and the PWM speed modulation generator, which is used for fast speed control.

At the heart of the NCP81166MNTBG is its proprietary algorithm, which delivers precise current control. The output current is regulated by a combination of an integrated power switch, the charge pump, and dedicated hardware. The hardware has two main components — the current sense resistors and the soft-start circuitry. The current sense resistors are used to detect the load current, while the soft-start circuitry is used to prevent excessive inrush current when the motor is started.

The NCP81166MNTBG is a highly advanced motor driver that offers excellent performance and reliability. It has integrated current sense resistors and a programmable soft-start to ensure maximum protection of the motor, as well as advanced features such as PWM thermal protection, under-voltage lockout, and over-temperature lockout. Additionally, it has a proprietary algorithm for precise current control and various operational modes to suit different drives. All these features make the NCP81166MNTBG an ideal choice for high-performance motor drives.
