AL8116W6-7

Overview

The AL8116W6-7 is a dimming signal interface controller manufactured by Diodes Incorporated in an SOT26 (Type CJ) package. It accepts three input types: 0 to 10V DC linear dimming, PWM signals from 0.2kHz to 10kHz, and resistive potentiometers up to 100kΩ. The device operates on a supply voltage range of 10V to 56V with a typical operating current of 600μA. It converts inputs into an open-drain PWM output with a frequency of approximately 1.5kHz and a duty cycle accuracy of ±2.5%. Minimum output duty cycles can be clamped at 2%, 4%, 6%, or 8% via the CLAMP pin. The component includes built-in auto-recoverable over-temperature protection.

Feature Summary

• Supports flexible dimming signal interfaces including 0 to 10V DC, PWM, and potentiometer inputs
• Provides adjustable bias current source for DIM pin compatibility with active and passive dimmers
• Features accurate output duty cycle tolerance and adjustable minimum output PWM duty clamping
• Includes internal auto-recoverable over-temperature protection

Applications

• 0 to 10V Dimming Luminaires
• Dimmable LED Power Supply
• Commercial LED Lighting
• Smart LED Lighting

Procurement Notes

Verify the specific ordering suffix W6-7 corresponds to the SOT26 package and tape & reel quantity of 3000 units. Confirm RoHS compliance and Halogen-free status requirements against project specifications. Ensure the application circuit accommodates the recommended VCC decoupling capacitor placement near the IC for stable operation.

Selection Notes

Select this component when isolation dimming control via opto-coupler is required for primary side LED drivers. Verify that the input signal amplitude meets the high level threshold of 3.2V for PWM mode. Ensure the system supply voltage remains within the 10V to 56V operating range and consider the thermal resistance characteristics for the SOT26 package under expected ambient conditions.

Part Context

The AL8116 series serves as a 3-in-1 dimming signal interface controller designed to reduce external component count and PCB size. It integrates functions to convert various dimmer types into a standardized PWM output suitable for controlling LED power supplies. The W6-7 designation specifically identifies the SOT26 surface-mount package configuration.
