The NCV78702MW0R2G is a high-side driver device that is primarily designed for use in applications such as light-emitting diode (LED) lighting, automotive and industrial applications. The device is designed to apply a regulated current to a load, while regulating the output current to eliminate the need for external ballast resistors. In addition, the NCV78702MW0R2G offers internal controlled shutdown, cycle-by-cycle peak current limit and open LED detection with hysteresis, a proprietary current sensing scheme, robust current limit protection and advanced features such as temperature monitoring and protection, fault output signal and low-power standby.

The NCV78702MW0R2G is a Pulse Width Modulation (PWM) LED driver that can be used to control the brightness and color of LED lighting. The device has two inputs that are used to control the LED output current and the frequency of the PWM signal. The first input is the reference voltage, or Vin, which determines the maximum current that is allowed to flow through the LED. The second pin is the PWM input, which controls the duty cycle of the LED current. When the PWM input is low, the LED current is at its maximum and when the PWM input is high, the LED current is at its minimum.

The NCV78702 Regulates the LED current by sensing the voltage on the current sensing resistor and competes with an internal reference voltage. This is achieved by setting an internal current limit and adjusting the duty cycle of the PWM output in order to keep the voltage on the current sensing resistor at the set current limit. The device is programmed as an open-loop system, meaning that no feedback information is required to regulate the output current.

The device is designed with enhanced transient reponse, allowing for fast and accurate current regulation over a wide range of dimming durations. In addition, the NCV78702 is protected against input voltage transients which can be caused by external switches, pots or EMI. The device also includes advanced features such as under-voltage lockout (UVLO) protection, short-circuit protection, thermal shutdown and open LED protection.

The NCV78702MW0R2G is suitable for use in applications such as LED lighting, automotive and industrial applications. It provides a high efficiency, reliable solution with minimal external components required, and is suitable for a wide range of dimming requirements and ambient temperatures. Furthermore, it provides a robust protection suite and a wide LED current range of 1.25A with a precision current limit of 0.1mA for improved efficiency and extended LED lifetime.
