Overview
The AL1783T16E-13 is a three-output linear LED driver IC manufactured by Diodes Incorporated. It operates with an input voltage range of 6.5 V to 55 V and supports PWM dimming. The device features three independent channels, each capable of delivering up to 125 mA of output current. It utilizes a TSSOP-16EP package for surface mount installation. The component functions within a temperature range of -40°C to +125°C and includes built-in thermal protection mechanisms to ensure reliable operation in LED lighting applications.
Feature Summary
- Provides three independent linear drive channels for precise LED current control
- Supports pulse-width modulation (PWM) dimming for brightness adjustment
- Integrates thermal shutdown protection to safeguard against overheating
Applications
- General LED lighting fixtures requiring multi-channel drive
- Commercial lighting systems utilizing PWM dimming controls
- Industrial LED arrays needing linear regulation
Procurement Notes
Verify the specific suffix 'E-13' to confirm tape and reel packaging quantities. Ensure the TSSOP-16EP footprint matches the target PCB design. Confirm RoHS compliance status through official manufacturer documentation before integration. Cross-reference the datasheet revision date to validate parameter accuracy against current production standards.
Selection Notes
Select this component when a linear topology is preferred for low-noise LED driving. The three-channel architecture simplifies designs requiring independent control of multiple LED strings. Verify that the maximum input voltage does not exceed 55 V under all operating conditions. Consider the thermal dissipation requirements of the TSSOP-16EP package for high-current applications.
Part Context
This part belongs to the AL1783 series of linear LED drivers from Diodes Incorporated. It is designed specifically for applications requiring multiple independent LED channels without the complexity of switching regulators. The EP variant indicates an exposed pad for enhanced thermal performance compared to standard packages.
Replacement Considerations
Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify that substitute parts maintain the same 125 mA per channel current rating and 55 V maximum input voltage limits. Ensure replacement components support identical PWM dimming frequencies and thermal protection thresholds.
