AS1113-BQFT

Overview

The AS1113-BQFT is a 16-channel LED driver IC manufactured by ams OSRAM, designed for high-brightness LED applications. It features linear shift register dimming with a maximum output current of 50 mA per channel. The device operates on a supply voltage range of 3 V to 5.5 V and supports an operating frequency of 50 MHz. It is housed in a 28-QFN (5x5 mm) package with exposed pad. The component functions within a temperature range of -40°C to +85°C and includes diagnostic capabilities for monitoring channel status.

Feature Summary

• Provides independent control for up to 16 LED channels via linear shift register architecture
• Integrates diagnostic functionality to monitor output channel states
• Supports serial interface communication for configuration and data transfer

Applications

• High-brightness LED lighting systems
• Automotive interior illumination modules
• General-purpose LED matrix displays

Procurement Notes

Verify the specific suffix BQFT against official datasheets to confirm the 28-QFN package and pinout compatibility. Confirm that the intended application environment remains within the specified -40°C to +85°C operational temperature limits. Ensure power supply voltages do not exceed the 5.5 V maximum rating to prevent device damage. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when a compact solution for driving multiple high-brightness LEDs is required. The 28-QFN package offers a small footprint suitable for space-constrained designs. The integrated diagnostics feature aids in system reliability and fault detection. Ensure the host microcontroller can support the required serial interface speed and protocol for proper operation.

Part Context

This part belongs to the AS1113 family of LED drivers from ams OSRAM, which are engineered for efficient LED management. The family typically includes variants with different packaging options such as SSOP-24 or QFN-28. These drivers are commonly utilized in applications requiring precise current control and multi-channel scalability for lighting and display purposes.

Replacement Considerations

The AS1113-BSST is a documented variant within the same product family, offering similar functional characteristics but utilizing an SSOP-24 package instead of the QFN-28 form factor. Verify pin-to-pin compatibility and thermal performance differences before substitution.
