KTZ8864AEJAA-TR

Overview

The KTZ8864AEJAA-TR is a high-efficiency LED backlight driver IC from Kinetic Technologies, designed for diverse display applications. It features four independent output channels with a boost topology, delivering up to 150 mA per channel. The device operates within a supply voltage range of 2.9 V to 5.5 V and supports an operating frequency range of 100 Hz to 100 kHz. Integrated dual LCD bias power management ensures reliable display operation alongside LED driving. The component is housed in a compact WLCSP-24 package and functions reliably across temperatures from -40°C to +85°C.

Feature Summary

• Integrates dual LCD bias power generation for comprehensive display panel support
• Supports I2C and PWM dual dimming control schemes for flexible brightness adjustment
• Provides four independent high-current LED output channels
• Utilizes a boost converter topology for efficient LED string driving

Applications

• Mobile device LCD backlight systems
• Tablet display illumination modules
• Portable electronic device lighting drivers
• Embedded display subsystems requiring integrated bias power

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and variant selection. Confirm that the required output current and voltage specifications align with the target LED array design. Check for updated revision levels or alternative package options if space constraints differ from the standard WLCSP-24 footprint. Ensure compatibility with the host system's I2C bus voltage levels and PWM signal requirements before finalizing procurement.

Selection Notes

Select this component when a single-chip solution for both LED backlighting and LCD bias generation is required. It is suitable for designs prioritizing board space efficiency due to the WLCSP-24 package. Consider the 150 mA output capability for moderate-to-high brightness LED strings. Evaluate the I2C/PWM interface compatibility with the main processor. This part is appropriate for consumer electronics where power efficiency and thermal performance are critical constraints.

Part Context

This device belongs to the KTZ8864A series of LED lighting drivers from Kinetic Technologies. The series focuses on integrating multiple power stages into small footprints for portable electronics. Similar parts in the family may vary in channel count or maximum output current but share the core architecture for combined LED and LCD bias management.

Replacement Considerations

Direct substitutes include other 4-channel LED drivers with integrated LCD bias from Kinetic Technologies, such as variants within the same KTZ886x family. Cross-manufacturer replacements require matching the boost topology, 4-channel configuration, and WLCSP-24 package dimensions. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
