Motor drivers and controllers are components of a power management integrated circuit (PMIC) that are used in many electronic systems to control the direction and speed of motors. The NJM3771D2 is a high current, adjustable speed PMIC specifically designed for motor control applications. This article will discuss the application field and working principle of the NJM3771D2.

The NJM3771D2 is a three-phase brushless DC motor driver with PWM current control, providing precise current control of motor drives. As such, the NJM3771D2 is used to drive the motor current accurately while controlling the motor speed. The NJM3771D2 is ideal for applications such as servo drives, robot arms, automated manufacturing equipment, and automated valve control.

The NJM3771D2 has two control modes: open loop control and closed loop control. The open loop control uses pulse width modulation (PWM) to control motor current, while closed loop control uses closed loop current sensing to maintain precise control of the motor current. The open loop control allows the user to easily adjust the motor speed and current, while the closed loop control provides accurate and stable motor current control.

The NJM3771D2 is designed to provide low noise, high linearity, and low current ripple performance. The device has an input voltage range of up to 40V and a current rating of up to 40A. In addition, the NJM3771D2 provides a wide frequency range, from 0 to 16KHz, so that it can be used in a variety of motor control applications.

The NJM3771D2 is also designed to provide a high level of protection against over-current, short circuit protection, and over-temperature protection. The device includes a dedicated Open Loop (OL) alarm output to indicate when an over-current or short circuit condition has occurred. The NJM3771D2 also features an over-temperature protection circuit to protect the device from excessive temperature.

The NJM3771D2 contains a number of features that make it ideal for motor control applications. It has adjustable PWM current control, a wide input voltage range, low current ripple, and over-current, short circuit and over-temperature protection. The NJM3771D2 is a powerful, reliable, and user friendly PMIC for motor control applications.
