Overview
The AS3693C-ZTQT is a 9-channel LED controller IC from ams-OSRAM, designed for backlight applications. It operates within an output voltage range of 0.4V to 50V and utilizes a 44-LQFP package. The device supports PWM dimming and features a moisture sensitivity level (MSL) of 3, corresponding to 168 hours of exposure. Classified under EAR99, this component serves as a dedicated driver for managing multiple LED channels in display systems.
Feature Summary
- Provides nine independent output channels for precise LED control
- Supports pulse-width modulation (PWM) dimming capabilities
- Engineered specifically for backlight application requirements
Applications
- Display backlighting systems
- Multi-channel LED driver circuits
Procurement Notes
Verify the specific ordering suffix ZTQT against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the 44-LQFP configuration. Cross-reference the MSL rating with your facility's floor life management protocols before assembly. Confirm that the 0.4V to 50V output range aligns with your system's power supply design constraints.
Selection Notes
Select this component when a high channel count is required for uniform backlight distribution. The integrated PWM functionality allows for efficient brightness control without external microcontrollers for basic dimming tasks. Consider the 44-LQFP package size relative to available board space. Verify thermal performance requirements against the expected power dissipation across all nine channels during operation.
Part Context
This part belongs to the AS3693 family of LED controllers from ams-OSRAM. These devices are positioned within the Power Management IC (PMIC) category, specifically targeting LED driving functions. The series is known for integrating multiple drivers into a single compact solution, reducing component count in complex lighting architectures.
Replacement Considerations
Check for direct pin-compatible alternatives within the same AS3693 series, such as variants with different suffixes or channel counts. Verify electrical parameters like output voltage limits and operating temperature ranges before substituting.
