TLC5960DAR

TLC5960DAR application field and working principle

TLC5960DAR is a great example of a PMIC-LED driver, which is a technology frequently used in industries ranging from automotive to consumer electronics. It is a 4-channel constant current driver capable of delivering 8A of continuous output with a secure serial digital interface, making it a great choice for driving high-power LEDs.

Introduction to TLC5960DAR

The TLC5960DAR is a high-performance 4-channel LED driver that comes with a wide range of features and is capable of delivering up to 8A of continuous output power which can be regulated using its SPI/UART interfaces, making it ideal for a variety of LED applications. It has a wide voltage tolerance, up to 36V, and auto-detects the shorts, open circuits, and over-temperature conditions in the LED loading. The device has built-in LED stripes hand-shake protection, allowing the LED driver to recover from the overload and start up again without data loss. It also come with buck-boost supply with precision current control.

Applications of TLC5960DAR

Due to the impressive characteristics of this device, the TLC5960DAR is a popular choice for applications where high power LEDs need to be driven, such as automotive headlamps, automotive taillights and backlighting solutions. The features, like the auto-detecting shorts, open circuits, and over-temperature conditions, make this device ideal for applications where safety is a critical aspect. Additionally, the wide voltage range, from 5V to 36V, makes it a suitable choice for applications where the power supply can vary a lot.

Working Principle of TLC5960DAR

The TLC5960DAR works by using a control register to adjust the control signals which regulate the current output. The control signals include the normal mode, which uses duty cycle to control the LED brightness, the low side current setting, and the high side current setting which can be adjusted to fine-tune the output current within milliseconds. The TLC5960DAR also has the ability to switch between a fast startup mode and a slow startup mode, allowing for faster response time.

Conclusion

The TLC5960DAR is a great example of an LED driver capable of controlling high current LED applications, from automotive headlamps to consumer applications. It is a 4-channel constant current driver with a secure serial digital interface and a wide voltage range for a variety of LED applications. The device also has built-in LED stripe hand-shake protection, auto-detects the short circuit or open circuit, and over-temperature conditions.
