Overview
The AL5802LP-7 is a linear LED driver IC manufactured by Diodes Incorporated, designed for adjustable current sinking applications. It operates within a supply voltage range of 5V to 24V and supports an output voltage up to 30V. The device features a single channel with an open-collector output capable of delivering 150mA. Packaged in a compact DFN-1616-6 (U-DFN1616-6 Type F) surface-mount format, it functions across a temperature range of -40°C to +150°C with a power dissipation rating of 500mW.
Feature Summary
- Combines high gain NPN transistor with pre-biased NPN transistor for simple small footprint design
- Open-collector output enables operation from 0.8V to 30V without additional components
- Integrated reverse polarity protection functionality
Applications
- LED lighting driver circuits
- Current regulation for LED arrays
- General purpose LED indicator drivers
Procurement Notes
Verify the specific suffix 'LP-7' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status through the latest documentation. Ensure the component matches the required operating temperature range and current sink capabilities for the target application before procurement.
Selection Notes
Select this component when a simple, low-component-count LED driver is required. The integrated pre-biasing simplifies circuit design compared to discrete solutions. Verify that the 150mA output current meets load requirements and that the DFN-1616-6 package fits the PCB layout constraints.
Part Context
This part belongs to the AL580 series of linear LED drivers from Diodes Incorporated. It is distinct from other variants like the AL5802-7 which may use different packaging such as SOT-26. The LP-7 designation specifically indicates the DFN-1616-6 surface mount package configuration.
Replacement Considerations
Check for direct substitutes within the AL580 family, such as AL5802-7, ensuring pin compatibility and package differences are accounted for. Verify if alternative manufacturers offer functionally equivalent linear LED drivers with matching current sink ratings and voltage ranges.
