The TLC5928DBQR is a QFN packaged device that is part of a series of power management integrated circuits, commonly referred to as PMIC - LED Drivers. It is a high current sink (commonly referred to as a "sinking driver”) for controlling up to 16 LEDs without the need for a microcontroller. The TLC592DBQR is capable of providing up to 20mA of output current per channel with no additional external components. It can be used in a variety of applications, from automotive to home appliance or industrial designs.

This LED driver has an operating temperature range from -40°C to +85°C and is designed to withstand higher current levels than typical LED drivers and dimmers. The TLC5928DBQR comes with integrated protection against input overvoltage (up to 28V) and undervoltage lockout. In addition, the device also includes thermal protection to protect it from overheating.

The TLC5928DBQR operates with a simple serial interface. It features an Input Data Interface (IDI) and Output Data Interface (ODI) and is controlled through an 8-bit serial interface. The device supports various output modes, including PWM, LED dimming and LED phase control, allowing it to be used in a wide range of applications. The output current is adjustable, making it ideal for applications that require precise current control.

The TLC5928DBQR’s built-in constant current control circuit ensures a stable output current regardless of the input voltage. The device can also be used as a voltage controlled PWM generator, using its Latch-In (LI) pin as the input for a wave generator or programmable logic device to set the duty cycle of each channel. The device also offers up to 24-bit grayscale capability, allowing it to accurately dim or mix colors from LEDs.

The TLC5928DBQR is well suited for applications in the automotive, home appliance, and industrial markets. It can be used to control a wide range of LED indicators, displays, and lighting applications. It is also suitable for pulse modulation applications such as pulse width modulation (PWM) and phase control dimming.

In summary, the TLC5928DBQR is a highly integrated PMIC - LED driver with a wide operating temperature range and integrated overload protection. It offers a simple serial interface and a wide range of output modes, making it ideal for a wide range of applications, from automotive to home appliance or industrial designs. It can be used to accurately control up to 16 LEDs, providing a stable output current at different input voltages.
