AS1110-BQFR

Overview

The AS1110-BQFR is a constant-current, 16-channel LED driver IC manufactured by ams OSRAM. It features an internal shift register topology for serial data input and supports PWM dimming operations. The device provides individual channel current control with a maximum output voltage of 15V per channel and a supply voltage range of 3V to 5.5V. It includes diagnostic capabilities for open-load and short-to-ground detection. The component is housed in a 24-SSOP package and operates within a temperature range of -40°C to +85°C.

Feature Summary

Integrates 16 independent constant-current channels with individual brightness control
Includes diagnostic functions for detecting open loads and short circuits
Supports high-frequency PWM dimming for flicker-free operation
Utilizes a serial interface for simplified connection to microcontrollers

Applications

Signage and display backlighting systems
Industrial indicator panels
Automotive interior lighting modules

Procurement Notes

Verify the specific suffix BQFR against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Check for end-of-life notices or alternative recommendations from ams OSRAM, as component availability may vary. Ensure design-in documentation matches the required operating temperature and voltage specifications for the target application environment.

Selection Notes

Select this component when a high-density solution for driving multiple LEDs is required without external current-setting resistors. The integrated diagnostics simplify fault detection in critical applications. Consider the 24-SSOP package constraints for PCB layout. Verify that the system's logic levels are compatible with the serial interface requirements before integration into the design.

Part Context

This part belongs to the AS1110 series of LED drivers designed for applications requiring precise current regulation across multiple channels. The series is characterized by its ability to handle complex lighting patterns through serial communication. It serves as a specialized power management IC within the broader portfolio of ams OSRAM's digital photonics solutions.
