PMIC - LED Drivers

STP16CPP05TTR application field and working principle

The STP16CPP05TTR is an advanced low-cost LED driver IC developed by STMicroelectronics. It is specifically designed for driving LEDs, such as dot matrix LCD backlight applications and indicating applications. This driver IC combines the functions of a transimpedance amplifier (TIA) and a short-circuit protected output driver into a single integrated circuit. It provides excellent functionality to drive four independent groups of LEDs. Its low-power technology and internal digital reset circuit make it well suited for LED display applications.

The primary application field for the STP16CPP05TTR driver IC is the LED backlighting of LCD displays, such as dot matrix displays. It has a wide range of features that make it ideal for driving LED displays. These features include current sink drive of up to 16 LEDs, supply voltage range from 4.5V to 18V, and output current range from 0.01mA to 500mA.

The output current of the STP16CPP05TTR can be controlled through either an external Crystal Oscillator (XO) or an external circuit connected to its Oscillator Input pin. It also includes programmable Ramp Slope, Analog Dimming Range and Digital Dimming Range. The inclusion of an internal digital reset circuit in the IC keeps its output current levels stable even after power-up. This IC also features thermal overload protection, current overload protection and over-voltage protection.

The working principle of the STP16CPP05TTR is presented on its Block Diagram. The device comprises of several basic blocks. These include a bandgap reference generator, two transimpedance amplifiers (TIA), four LED drivers and an oscillator. The bandgap reference generator produces a reference voltage to set the LED current output by the following blocks. Transimpedance amplifiers consist of a differential pair amplifier and a voltage follower used to convert the current level into a voltage level. This voltage is used to control the current sinking level of the drivers. The four LED drivers based on BS263 fundamentals convert the control voltage into an LED current. The oscillator is responsible for controlling the control voltage that the drivers use.

The STP16CPP05TTR is a highly efficient and low-cost LED driver IC for a variety of applications such as backlighting of LCD displays and indicating applications. Its low power technology, programmable features and internal digital reset circuit offer excellent features for driving LEDs. The device\'s operation is based on the fundamental principles of bandgap references, transimpedance amplifiers, and BS263 fundamentals for the LED drivers.
