IS31LT3354-STLS2-TR Integrated Circuits (ICs)

The IS31LT3354-STLS2-TR is a general-purpose linear LED driver, part of a larger family of PMIC - LED Driver products from ISSI. The family, from ISSI provides a wide range of options for all types of general-purpose and automotive audio, industrial, and IoT applications. The IS31LT3354-STLS2-TR part provides a complete design solution for enabling the electrically powered illumination of one and two-color LED arrays.

The IS31LT3354-STLS2-TR part is a single-channel, PWM and I2C controlled LED driver. It features programmable PWM duty cycle and CTRL output power in response to external control signals and is designed to drive two lines of up to 25 mA LED current per color. The part also features an integrated protection circuit and is designed to support LED fault/monitoring applications.

The IS31LT3354-STLS2-TR part provides a 95% efficiency rating, making it suitable for automotive, audio, industrial, and IoT applications alike that require bright, power-efficient LED lighting for any task. The integrated protection circuit on the part protects the user from over-voltage, over-current, and overtemperature conditions, ensuring a long life and superior performance.

In terms of the working principle, the IS31LT3354-STLS2-TR takes in an external control signal and uses Pulse Width Modulation (PWM) to regulate the current or voltage to the LED. This allows the light to be adjusted, allowing the user control over the exact brightness of the LED. Based on this external control signal, the PWM duty cycle and/or the CTRL output power can be adjusted. The IS31LT3354-STLS2-TR also supports 1-wire serial interface for LED fault/monitoring and power-on reset.

The IS31LT3354-STLS2-TR is a unique IC that is ideal for applications requiring LED lighting solutions. Its integrated protection circuit, 95% efficiency rating, and ability to control LED current/voltage make it a versatile and reliable chip for any application. It is suitable for applications such as automotive audio, industrial, and IoT applications that need bright and efficient LED lighting solutions.
