PCA8543AHL/AY

Display Drivers Overview

The PCA8543AHL/AY is an automotive-grade LCD segment driver manufactured by NXP Semiconductors. It supports a configuration of four backplanes and sixty segments, packaged in a TSSOP-56 form factor. The device operates within a supply voltage range of 1.8 V to 5.5 V and features a maximum clock frequency of 5 MHz. It is designed for low-power applications with a maximum power dissipation of 400 mW and functions reliably across temperatures from -40°C to +95°C.

Display Drivers Feature Summary

• Integrated programmable charge pump for generating required LCD bias voltages
• Built-in temperature compensation system for stable display performance
• Supports multiplex rates up to 1:4 for efficient segment driving

Display Drivers Applications

• Automotive instrument cluster displays
• Vehicle infotainment control panels
• Dashboard indicator modules

Display Drivers Procurement Notes

Verify the specific suffix 'AHL' against official documentation to confirm package type and tape/reel specifications. Confirm current lifecycle status as automotive components often undergo long-term availability reviews. Ensure compatibility with existing PCB footprints and SPI interface requirements before procurement.

Display Drivers Selection Notes

Select this component when designing automotive displays requiring integrated voltage generation without external boost circuits. The built-in temperature compensation simplifies design complexity compared to standard drivers. Verify that the 4-backplane, 60-segment capacity matches the target display matrix dimensions.

Display Drivers Part Context

This part belongs to the PCA854x family of LCD drivers optimized for automotive environments. It shares functional similarities with the PCA8546 but offers distinct segment counts and internal charge pump configurations tailored for specific display sizes and multiplexing requirements in vehicle electronics.

Display Drivers Replacement Considerations

Consult official substitution lists for form-fit-function compatible alternatives. Direct replacements must maintain the TSSOP-56 package and support 4-backplane operation.
