AS1110-BQFT

Overview

The AS1110-BQFT is a constant-current, 16-channel LED driver IC manufactured by ams OSRAM. It features internal linear switches and supports PWM dimming for display applications. The device operates on a supply voltage range of 3V to 5.5V with a maximum output voltage of 15V per channel. Each channel provides up to 100mA of drive current. It utilizes a shift register interface for data input and is housed in a 24-SSOP package. The component is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides 16 independent constant-current channels for high-density LED matrix driving
• Integrates internal linear switches to simplify external circuit design
• Supports pulse-width modulation (PWM) dimming for precise brightness control

Applications

• Signage displays
• LED matrix panels
• Digital signage

Procurement Notes

Verify the specific suffix BQFT against official datasheets to confirm package type and tape/reel specifications. Confirm end-of-life status as distribution availability may be limited. Ensure compatibility with existing PCB footprints for the 24-SSOP package before procurement.

Selection Notes

Select this component for designs requiring multiple synchronized LED outputs with integrated switching. It is suitable for applications needing linear regulation without external MOSFETs. Consider thermal management requirements given the SSOP package constraints and continuous current operation.

Part Context

This part belongs to the AS1110 series of LED drivers from ams OSRAM. The series is designed for general-purpose LED matrix applications. Variants within the series differ primarily in package options and minor electrical characteristics while maintaining the core 16-channel functionality.

Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer family. Verify that alternative components support the required 16-channel count and 100mA per channel specification.
