LEDs, or light-emitting diodes, are widely used in circuit board indicators, arrays, light bars, and bar graphs. The H485CHD, an integrated circuit developed by Intersil Corporation, can drive LEDs to produce attractive and attractive bar graphs.

The H485CHD is an 8-channel, constant current LED driver designed to provide high-contrast and high-intensity displays with a wide range of flexibility. The H485CHD supports up to eight LEDs per channel, with a maximum rating of up to 20mA. With a maximum output current of up to 10mA per channel, the H485CHD can drive up to 80 LEDS simultaneously.

The key feature of the H485CHD is its ability to operate over a wide range of dimming ratios. H485CHD uses Pulse Width Modulation (PWM) to control the LED current and the LED brightness, allowing for very fast response time, low jitter, and low noise to achieve high-dynamic range dimming. The dimming ratio of the H485CHD can range from 0.1 to 90.7, providing a wide range of flexibility in different applications.

The H485CHD has an integrated LED “snubbing” capability. Snubbing helps to protect the LED from damage due to unexpected power draw, and can help prevent the LED from overloading. Additionally, the H485CHD has an adjustable current limit, so that the LEDs never draw more than the specified current. This can help to protect the LED as well as the circuit board from damage.

The H485CHD can be used for many applications that require LED display or indication. These include, but are not limited to, industrial equipment, automotive lighting systems, home entertainment systems, and medical imaging. The H485CHD can be used to drive the LEDs in any of these applications in an efficient and attractive way.

In addition to driving LEDs, the H485CHD can be used for brightening or dimming of lighting systems, color mixing for design and decoration, and even for providing direct control of a motor, fan, or other actuator. The H485CHD has built-in protection against thermal runaway and open circuit conditions, allowing it to operate safely in a wide range of conditions.

The H485CHD is a versatile and efficient LED driver, suitable for many applications. Its wide output current range and wide range of dimming ratios enable it to provide a wide range of lighting solutions. With its integrated LED snubbing capability, the H485CHD helps to protect the LED and the circuit board from damage. Its built-in protection against thermal runaway and open circuit conditions makes it a safe and reliable choice for driving LEDs in lighting and display applications. Its high-performance, low-noise operation makes the H485CHD an ideal choice for high-dynamic range dimming and other LED-driven applications.
