FAN5616MPX Integrated Circuits (ICs)

FAN5616MPX is an LED driver integrated circuit (IC) manufactured by FANUC. It is a Part Number Entry Single-LED Constant Current Programmable LED Driver and is part of the FANUC PMIC-LED Drivers family. The driver is intended to drive single LEDs, and features Programmable Constant Current Output and High Efficiency.

The FAN5616MPX contains a power MOSFET, which is a current-controlled device with a low on-resistance. The MOSFET controls the current flow through the external LEDs. A voltage source, typically supplied by the main power source, is connected to the MOSFET through a resistor. The resistor will regulate the amount of current flowing through the MOSFET. The current flowing in the MOSFET is in turn regulated by adjusting the voltage across the MOSFET gate. This can be done by connecting the gate to a voltage source via a resistor.

The FAN5616MPX can be programmed using either a direct logic or an external programming source. When using a direct logic connection, a compatible digital signal (3.3V/5V) is connected to the input pin of the driver. When an external programming source is used, it can be either a pulse width modulation signal (PWM) or an analog voltage signal. After programming, the driver output will draw a constant amount of current through the external LEDs.

The FAN5616MPX is ideal for applications where constant current control is required, such as LED lighting and general dimming applications. It provides precise dimming control and allows for a wide range of LED current levels. The FAN5616MPX also features an accurate current limit and can set the current level with minimal temperature variation. Additionally, the driver provides motion detection and indirect measurement of LED current to ensure LED safety.

The FAN5616MPX is capable of driving up to 500mA of current and achieves a high efficiency of over 90%. This driver provides an industry-leading competitiveness in terms of price and performance, making it a viable and attractive solution for a wide range of LED driving applications.
