IACS CO., LIMITED (Yiwu Fuwei e-commerce firm)

Integrated Silicon Solution, Inc., a pacesetter in advanced memory and analog IC solutions, today announced a single chip solution for automotive interior lighting. The IS32LT3175 is really a feature-rich AEC-Q100 (Automotive Electronics Council) certified linear LED driver enabling reduced BOM count for low-cost little designs. The IS32LT3175 integrates a single channel LED driver with a programmable 150mA current source, push-button control, courtesy signal input and integrated programmable fade-in/fade-out lighting control. The device is for use in LED-based map lights, dome lights, door lights along with other automotive lighting applications.

The IS32LT3175 integrates all functions, eliminating the requirement of a microcontroller and several discrete components. Individual resistors are enough to alter the LED current from 10 to 150mA along with the fade up/down ramp speed there isn't any software programming required. The LED driver could be controlled by sometimes a momentary contact switch or possibly a courtesy signal input. An integrated debounce and latch circuit conditions the switch input so an individual press from the mechanical switch won't seem like multiple presses.

Key product or service benefits in the IS32LT3175 include:

1, Reduced BOM: LED driver with theatrical dimming in a single small 8 pin SOP package resulting in 65% less components requiring less pcb area.

2, Linear LED Driver: Low-noise, low-EMI, linear current source adjustable from 10~150 mA into more than one LEDs.

3, Switch Input: Integrates switch debounce and latching logic to enable utilization of affordable momentary contact switch. The startPerAway from state is held during start-stop operation when voltage drops below 6V for a while of energy.

4, Local or Remote: Could be controlled remotely from the automobile's microcontroller or locally which has a momentary contact switch. The local switch has priority over the remote microcontroller giving the user with direct control of the LED lamp.

5, No Microcontroller: Advanced LED performance can be adjusted with simple resistors, eliminating the requirement for a microcontroller.

6,AEC-Q100: Meets stress testing specifications rendering it suitable for use within the tough automotive environment with guaranteed operation from -40 degree to +125 degree.

The Automotive Lighting information mill projected to grow at a CAGR of 7.22% from 2016 to 2021 and reach USD 29.53 billion by 2021 according to market reports. LED could be the fastest growing technology in automotive lighting market since it is energy efficient, lightweight little. These attributes lead to the rapid growth and increased adoption in autos worldwide. "IS32LT3175 is a feature rich LED Driver which is robust and simple to create with," said Ven Shan, VP of Analog Products at ISSI. "This excellent product is exactly what premier auto makers are trying to find of their Map lights, Dome lights as well as other interior LED lighting designs to replace bulky incandescent bulbs for improved light efficiency and sleek designs."

The unit also integrates protection features, for example open and short LED fault detection, thermal rollback and thermal power down to raise system longevity and reliability. The LED current remains on the configured level so long as the junction die temperature in the IC remains below 145%uFFFDC (typical). If the die temperature exceeds this threshold, the output current from the device will begin to reduce at a rate of 3% degree. The device will enter thermal shutdown if your die temperature exceeds 175 degree.
