NJM3517E2 Application Field and Working Principle

NJM3517E2 belongs to the family of PMIC (power management integrated circuits) motor drivers, controllers, and belongs to the low-side and high-side driver controllers. This circuit is specifically designed to provide highly efficient performance and low-cost solutions. The NJM3517E2 driver controller has several features, including a step voltage control, a wide operating voltage ranging from 8 to 24V, and a short-circuit protection. This article will discuss the application field, working principle and features of the NJM3517E2 driver controller.

Application Field
NJM3517E2 driver controller can be applied in various applications, including motor drive applications, such as powering AC, DC, brushless DC motors and other motors, as well as for controlling lamps and relays. The controller is suitable for general purpose on/off controlling current and provides up to 16 channels. The switch can provide very low ON-resistance, which makes this driver controller suitable for controlling large currents. Additionally, the driver controller has considerable immunity to electrostatic discharge and can operate in temperatures of up to 150ºC.

Working Principle
The working principle of the NJM3517E2 driver controller is based on a voltage step control system. The controller is designed to control the supply voltage to the desired voltage, while the current is monitored in order to make sure that it is constant and within the operating temperature range. When the input voltage exceeds the limit, the unit automatically switches to the lowest voltage level and the output voltage is adjusted accordingly. This ensures that the output voltage stays within the safety limits of the device. The controller also monitors the current to detect any short-circuit situations, and if such a situation arises, the output voltage is immediately adjusted.
