OM13484UL is a UL recognized quad constant current LED driver with dedicated logic, integrating an adjustable 4 channel constant current output stage. This device is specifically designed to provide constant current to LEDs in lighting fixtures, as part of a UL recognized complete system. The power control is provided by four dedicated N-channel MOSFET outputs.

The OM13484UL features a wide input voltage range (8 V to 40 V, with current limiting up to 45 V) and a wide output current range (15 A to 160 A per channel). It is designed with an on-board open drain N-channel MOSFET to provide fast response and accurate regulation of the output current. The output current can be adjusted using an external resistor or a digital control (optically isolated or direct I2C/SPI connection). The device also features overvoltage and overtemperature protection, shutdown, active balance and fault detection.

The OM13484UL is an ideal solution for LED lighting applications, where it can be used to provide stable, constant current output to LEDs with excellent efficiency. and accuracy. The device is also suitable for dimming applications, as the output current can be adjusted via external resistor, or through digital control.

In terms of its working principle, the OM13484UL works by converting an input voltage to a stable constant current output. This is done through an adjustable four channel constant current output stage, which features an on-board open drain N-channel MOSFET to provide fast response to changes in the output current. The current can be adjusted using an external resistor or a digital control, and the device provides excellent efficiency and accuracy. In addition, the device also features overvoltage and overtemperature protection, shutdown, active balance and fault detection.

The OM13484UL is an ideal solution for LED lighting applications, providing a reliable, constant current output for LEDs with excellent efficiency and accuracy. Its wide input voltage range and wide output current range make it suitable for a variety of lighting fixtures, and its adjustable current output and digital control make it suitable for dimming applications as well. It is also designed with several safety features, making it a safe and reliable choice for use in UL recognized lighting fixtures.
