PCA8561BHN/AY

Display Drivers Overview

The PCA8561BHN/AY is an automotive-grade LCD segment driver manufactured by NXP Semiconductors. It features a 4 x 18 segment architecture with an I²C-bus interface, housed in a 32-pin HVQFN package (5x5 mm). The device operates on a supply voltage range of 1.8 V to 5.5 V, with a maximum clock frequency of 5 MHz and a typical supply current of 3 µA. It supports a power dissipation of 100 mW and functions within a temperature range of -40 °C to +105 °C.

Display Drivers Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 standards for harsh environment operation.
• Integrated charge pump circuitry eliminates the need for external high-voltage components.
• Supports direct connection to common cathode or common anode LCD panels via internal bias generation.

Display Drivers Applications

• Automotive instrument clusters and dashboard displays
• Industrial control panel interfaces
• Medical equipment display modules

Display Drivers Procurement Notes

Verify the specific suffix 'AY' against the official NXP datasheet to confirm package orientation and tape-and-reel specifications. Ensure the design accounts for the HVQFN-32 thermal pad requirements during PCB layout. Confirm that the selected variant meets the required AEC-Q100 qualification levels for the target automotive application zone.

Display Drivers Selection Notes

Select this component when designing systems requiring low-power, space-constrained LCD driving with I²C connectivity. The 4x18 segment configuration suits simple alphanumeric or icon-based displays. Consider the 1.8V minimum operating voltage for battery-powered applications and verify that the 5MHz bus speed aligns with the host microcontroller's capabilities.

Display Drivers Part Context

This part belongs to the PCA8561 family of LCD drivers from NXP Semiconductors. The family includes variants such as the PCA8561AHN/AY, which shares similar functional characteristics but may differ in specific electrical parameters or packaging details. These devices are designed to replace discrete driver solutions in compact electronic assemblies.

Display Drivers Replacement Considerations

The PCA8561AHN/AY is a related variant within the same product family. Verify pin compatibility and electrical specifications before substitution. No other direct cross-manufacturer replacements are confirmed in public documentation.
