STP16DPP05XTTR is an integrated circuit manufactured by ST Microelectronics for driving LEDs. It is used in PMIC (Power Management Integrated Circuit) applications, with the purpose of providing multiple controllable independent current sources for LEDs. This device can be controlled either with a logic level input or with a PWM signal.

The STP16DPP05XTTR is a 16-channel LED driver, providing a maximum output current of up to 1000 mA per channel. It\'s a low-voltage device, working with up to 12V supply. It includes both dimming support and regulation, which makes it suitable for applications requiring an adjustable LED current.

The LED driver combines a 500 mA linear regulator and a high-side MOSFET power switch, providing a precisely regulated current to each LED, without the need for external components. Each channel is independently dimmable from 0 to 100%, with no need of additional power resistors. An integrated PAL switch provides protection against over-current and short circuit events.

The STP16DPP05XTTR provides adjustable current regulation, which allows different current levels for each LED channel. A digital input is connected to all channels for turning off the LEDs and setting the current level. An SPI interface is implemented for setting the current level of each channel, as well as for reading back the modulation value of each channel.

The integrated PWM generator module, allows to control the output channels via a PWM signal, modulating up to 2 kHz, configured with a mode register. This register sets the number of PWM resolution steps, permitting the user to adjust the brightness of the LEDs.

The STP16DPP05XTTR is a very useful device for driving LEDs, providing a current control range from 0 to 1000mA per channel, controllable by logic level or PWM signal. It includes several protection features, such as a PAL switch and integrated thermal shutdown logic, making it stable and reliable for use in any application requiring the driving of multiple independent LEDs.
