BD1604MUV-E2 - PMIC - LED Drivers

The BD1604MUV-E2 is a member of ROHM Semiconductor\'s current regulators which integrates the power supply of LEDs or similar applications. This device is particularly suitable for replacement of traditional uses like ballasts, eliminating large and bulky components for simple, compact power supplies. The small size and minimal external component requirements have led to its widespread use in small, portable and low power consuming products.

Features

The BD1604MUV-E2 features a high led current accuracy of ±7% (at room temperature). It has an integrated PWM dimming function which is able to adjust light intensity up to 100,000 steps, and is compatible with various communication protocols such as PWM, I2C and PCM. The device also has a detection function which can detect the open/short (or reverse) connection of an LED, thereby preventing damage to the LEDs. The BD1604MUV-E2 also has built in protections such as over-current protection and over-voltage protection.

Application fields and working principle

The BD1604MUV-E2 is suitable for LED lighting applications such as LED signs, LED tubes, LED strips, and LED spotlights as well as other lighting applications. The device works by acting as a regulator to deliver an exact and consistent current to the LEDs, resulting in an even and stable light output.

The BD1604MUV-E2 delivers a continuous current to the LEDs and can be controlled through dimming control signals. The device includes an internal voltage comparator that determines the output current which is then adjusted with the help of a PWM signal to regulate the current delivered to the LEDs.

The device also has an onboard temperature sensor which controls and maintains the current level in order to prevent damage to the LEDs. It has a thermal protection feature which automatically shuts off the power supply when the temperature rises beyond a certain threshold.

Finally, the device includes an integrated safety circuit that prevents the flow of excessive current which may occur due to a fault condition, by shutting off the output in such cases and thereby protecting the system and the LEDs.

Conclusion

The BD1604MUV-E2 increases cost efficiency while maintaining high performance and reliability. It is ideal for applications that require a high level of integration, low power consumption, a wide range of dimming options, and reliable protection features.
