Overview
The AS1102-T is a low-dropout LED driver IC manufactured by ams-OSRAM. It features three independent outputs capable of delivering up to 40mA each. The device supports both analog and PWM dimming for precise light control. It operates within a supply voltage range of 4.3V to 5.5V. The component is housed in an SC-70-6 package with dimensions suitable for space-constrained designs. It functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Three independent linear output channels
- Supports analog and PWM dimming methods
- Low-dropout topology for efficiency
- Automotive-grade thermal performance
Applications
- Interior automotive lighting systems
- Ambient vehicle illumination
- Dashboard indicator circuits
- General-purpose LED driving
Procurement Notes
Verify the specific suffix and marking code against official datasheets to ensure correct pinout and functionality. Confirm that the SC-70-6 package matches your PCB footprint requirements. Check for moisture sensitivity levels if reflow soldering is planned. Ensure the input voltage range aligns with your system's power supply specifications before procurement.
Selection Notes
Select this component when three separate LED channels require individual current control within a compact form factor. The low-dropout design makes it suitable for applications where the supply voltage is close to the LED forward voltage. Consider the 40mA output limit per channel to ensure adequate brightness without exceeding ratings. Verify compatibility with your chosen dimming signal type, whether analog voltage or PWM frequency.
Part Context
This part belongs to ams-OSRAM's portfolio of intelligent LED drivers designed for automotive and industrial applications. It complements other drivers in the series by offering a balance of channel count and package size. The technology focuses on reliability and efficient power management for critical lighting functions.
Replacement Considerations
Check for direct substitutes with identical pinouts and electrical characteristics. Verify that alternative drivers support the same 40mA output current and dimming interfaces. Ensure the replacement package matches the SC-70-6 footprint to avoid PCB redesign.
