LEDs have become an indispensable part of modern life, from uses as simple indicators in household appliances, to night-lights, lighting for cars and large-scale signs. To drive a LED, an LED driver is a dedicated electronics device which delivers power from a power source to an LED load. TLC59211IN is one type of LED driver integrated Circuits (ICs) which is integrated into a single chip and can drive 88 separate outputs. In this article, we\'ll take a look at the application fields of TLC59211IN, as well as its working principle.

Application Fields of TLC59211IN

TLC59211IN is a low voltage LED driver as it operates with a supply voltage as low as 1.8V. It is designed to control up to 88 LED channels. This LED driver IC integrates six control methods on a single chip including brightness, dimming, PWM dimming, color, lookup table dimming, and individual PWM dimming. What\'s more, it offers low EMI emission rendering it suitable for automotive applications. This driver can be used for custom designs for automotive heads-up display, in-vehicle infotainment, TVS and LCD displays, telecom equipment, medical monitoring and other types of LED applications.

Working Principle of TLC59211IN

In terms of working principle, TLC59211IN enables switching of LED channels with very low power consumption. Each LED channel can be individually programmed by GPIO pins. As many pins require 1.8V logic, this driver IC will provide adequate operation in variable environments including automotive and outdoor applications. Furthermore, it can realize efficiently dimming of LED channels either individually or collectively. To achieve the desired PWM dimming, the IC can sense the external input signals, whether these signals are analog or PWM, effecting the performance of each channel. With this feature in hand, the user is able to control the dimming range of each channel. Therefore, TLC59211IN is able to effectively dim a wide variety of LEDs, including red, green, blue, amber and white LEDs.

Conclusion

In conclusion, TLC59211IN is an ideal LED driver for automotive displays, medical monitoring systems and a range of other LED applications. Its ability to support multiple control methods, low power consumption and universal operation make it a great choice for developers and engineers alike.
