Overview
The AS1114-BSOU is an LED driver IC from the ams OSRAM AS1114 series, designed for display and lighting applications. It features a linear topology with integrated internal switches and supports both analog and PWM dimming operations. The device operates within a supply voltage range of 3V to 5.5V and provides up to 50mA output current per channel across 16 channels. It is housed in an SSOP-24 package suitable for surface mount installation.
Feature Summary
- Supports simultaneous analog and PWM dimming control for precise brightness adjustment
- Integrates internal high-side switches for direct LED connection
- Provides constant current regulation across multiple output channels
Applications
- LED display drivers
- General illumination systems
- Backlighting units
Procurement Notes
Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notifications prior to procurement. Ensure storage conditions meet moisture sensitivity level requirements to prevent damage during assembly.
Selection Notes
Select this component when a multi-channel solution with mixed dimming capabilities is required. Consider the SSOP-24 package constraints and thermal dissipation needs. Evaluate compatibility with existing control interfaces for analog and PWM signals before finalizing the design.
Part Context
This part belongs to the AS111x family of LED drivers from ams OSRAM, which includes variants like the AS1110, AS1111, and AS1113. These components share similar linear topologies and dimming functionalities but differ in channel counts and specific electrical ratings tailored for various display and lighting densities.
Replacement Considerations
Check for pin-compatible alternatives within the same AS111x series. Verify that substitute parts maintain identical dimming interface requirements and output current specifications to ensure seamless integration without circuit redesign.
