LT8500ITJ

LED Driver IC Overview

The LT8500ITJ is a pulse width modulation (PWM) generator featuring 48 independent channels. It operates within an input voltage range of 3 to 5.5 V. Each channel includes an individually adjustable 12-bit (4096-step) PWM register and a 6-bit (64-step) ±50% correction register. The device utilizes a 56-pin TLA QFN EP package.

LED Driver IC Feature Summary

• Generates 48 independent PWM output channels for precise control applications
• Provides 12-bit resolution per channel with individual programmable registers
• Includes 6-bit correction registers allowing ±50% adjustment per channel

LED Driver IC Applications

• Digital-to-analog converter (DAC) channel implementation
• LED lighting driver systems
• Display backlight control
• Automotive indicator control

LED Driver IC Procurement Notes

Verify the specific ordering suffix, such as #PBF or #TRPBF, to confirm the correct packaging format required for your assembly process. Confirm that the component meets RoHS compliance standards if applicable to your manufacturing requirements. Ensure the supplier provides valid traceability documentation for quality assurance purposes before finalizing the purchase order.

LED Driver IC Selection Notes

Select this component when designing systems requiring high-channel-count PWM generation without external multiplexing. The integrated 12-bit resolution eliminates the need for additional DACs in many LED control scenarios. Consider the 56-pin TLA QFN EP package constraints regarding thermal dissipation and PCB layout space during the initial design phase.

LED Driver IC Part Context

The LT8500ITJ belongs to the LT8500 series of LED drivers manufactured by Analog Devices Inc. It is categorized under power management ICs specifically designed for LED lighting applications. The device serves as a dedicated PWM generator rather than a linear regulator or standard switching converter.

LED Driver IC Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing system architectures if considering alternative components from other manufacturers.
