Description and Application Field of H401CHD

H401CHD is an integrated circuit designed by NXP Semiconductor specifically for applications requiring high-brightness LEDs. It is an 8-channel infrared and visible light emitting diode controller that works with a wide variety of color LEDs. Its primary use is for the detection of various types of mobile payments, identification tags, and fingerprint recognition. It is also used in the design of high-brightness indicators in industrial controllers, lighting systems, and automotive instruments. In addition, this IC can be used in medical imaging systems, surveillance systems, and more.

H401CHD Work Principle

The H401CHD is a 3-wire, 8-channel LED driver that allows for high-speed modulation of LED brightness. The LED controller consists of two parts, the LED driver and power supply. The LED driver is an 8-bit shift-register that controls the current to the 8 channels. The power supply is generally a DC-DC converter, but can also be a buck converter depending on the application requirements. It supplies the necessary power to the LED driver.

When a control signal is inputted to the H401CHD, the shift-register begins to come into play. Each Bit of data inputted to the shift-register is sent to the corresponding channel and determines the level of current outputted to the LEDs. This allows for a wide variety of control possibilities, such as nonlinear dimming, pulse width modulation (PWM), intensity modulation, and more.
