LEDs have revolutionised the way we light up our lives and the EL1848IYZ motor-driver ICs have been a part of that revolutionary process. EL1848IYZ motor-driver ICs are particularly powerful when it comes to driving high-power LEDs in DC/PWM applications. This article will discuss the application field and working principle of the EL1848IYZ motor-driver ICs.

EL1848IYZ are known as high- and low-side PWM controller system-on-chip devices. The EL1848IYZ chips provide a wide range of power output for controlling high-power LEDs in DC/PWM applications. The built-in high voltage driver is capable of driving high-power LEDs up to 40V and up to 25mA. The EL1848IYZ chip is soldered using standard surface-mount technology (SMT) for ease of integration into the circuit.

The application field of the EL1848IYZ motor-driver ICs is quite diverse. For example, they are used in automotive headlights, lanterns, lights at various constructions sites, high-intensity discharge lamps, street lights, spot lights, etc. In addition, they are also used in many electronic appliances like LED strips and LED panels. Moreover, they can be used in LED systems for industrial and commercial applications like RGB LED lights.

The working principle of the EL1848IYZ motor-driver ICs is based on the current-mode control scheme. This scheme requires one external resistor as the reference voltage for current-mode control. When an appropriate level of current flows through the LED, the driver circuit will automatically switch to the off state in order to prevent the over-driving of the LED. The on/off switching action is controlled by a low voltage control signal from a microcontroller. The microcontroller will also monitor the current levels and make sure that they stay within the working range of the current-mode control scheme.

In addition to the current-mode control scheme, the EL1848IYZ motor-driver ICs also feature an over-current protection circuit. This helps protect the LED from being damaged in case of an overload. The EL1848IYZ motor-driver ICs also feature a thermal shutdown circuit to prevent damage from overheating. The EL1848IYZ also has a built-in soft-start feature, which gradually steps up the output current from a minimum level to its full power. This helps reduce LED noise and flicker.

In conclusion, the EL1848IYZ motor-driver ICs have a wide application field and a well-defined working principle for driving high-power LEDs in DC/PWM applications. The built-in features like the current-mode control scheme, over-current protection circuit and the thermal shutdown circuit provide reliable performance and guarantee the safety of LEDs. The EL1848IYZ motor-driver ICs are a great choice for any application that requires reliable and efficient LED driving.
