Introduction

MAN4640A is a kind of LED character and numeric display module from Nichia (NEC). This set of devices manufactures in a compact package and is an ideal solution for applications which require long-term reliability, high brightness, and low power consumption.

Application Fields

The MAN4640A is applied in a broad range of applications, such as for industrial control, office automation, automotive and home appliance related products such as cell phones or other communication devices, watches, toys, audio/video products, oscilloscopes and EMI/EMS management systems. The MAN4640A series is highly suited for medical instrumentation and medical equipment as well as in medical security and automation systems. It is also suited for use in production and management systems, audio and entertainment systems, industrial control systems, power monitoring systems and clock displays.

Working Principle

The MAN4640A is a monolithic LED (Light Emitting Diode) display module that offers a variety of LED characters and symbols. The device is composed of seven segmented LED characters with one or two decimal points, one or two illuminated dots at the lower left corner, and optional inverted characters. The seven segmented LED characters and the illuminated dots of the MAN4640A are driven by the N-channel MOSFET switch. Every character\'s current is independently controlled with the switch. The segment currents for each character are adjustable between 0.1 and 10mA to allow for optimizing the brightness for specific applications. The MOSFET switch also controls the power-on and power-off timing by resetting the display contents.

Conclusion

In conclusion, MAN4640A is a popular choice of LED character and numeric display module used in many applications. It is highly reliable, low power consuming, and offers adjustable current and brightness models that optimized brightness for specific application. With its compact size and flexibility, it is perfect for use in industrial control system, medical instrumentation and office automation.
