PCA8537AH/Q900/1,5

Display Drivers Overview

The PCA8537AH/Q900/1,5 is an automotive-grade LCD driver designed for high-contrast vertical alignment displays with multiplex rates up to 1:8. It supports up to eight backplanes and 46 segments, driving 352 elements. The device features a software-programmable internal charge pump generating voltages up to 9 V. It utilizes a 400 kHz I²C bus interface and includes programmable temperature compensation for the LCD supply voltage. Operating on a digital power supply from 1.8 V to 5.5 V, it integrates a 352-bit RAM for display data storage and a factory-calibrated frame frequency range of 60 Hz to 300 Hz.

Display Drivers Feature Summary

• Complies with AEC Q100 standards for automotive electronic applications
• Integrates a programmable internal charge pump with onboard capacitors for LCD voltage generation
• Provides programmable temperature compensation of the LCD supply voltage across four regions
• Includes an integrated temperature sensor with readout capability

Display Drivers Applications

• Automotive instrument clusters
• Car radios
• Climate control systems

Display Drivers Procurement Notes

Verify that the specific suffix /Q900/1,5 corresponds to the required tape-and-reel packaging configuration and dry pack status. Confirm the component meets the AEC Q100 qualification requirements for your specific automotive grade specifications. Ensure the ordering code matches the exact NXP part number to avoid discrepancies in package type or interface protocol.

Display Drivers Selection Notes

Select this component when designing systems requiring AEC Q100 compliance for automotive LCDs. It is suitable for vertical alignment displays needing multiplex rates up to 1:8. Choose this driver if the design requires an I²C interface rather than SPI, as indicated by the AH suffix. Consider its wide LCD supply range for varying threshold requirements.

Display Drivers Part Context

This part belongs to the PCA8537 family of fully featured LCD drivers manufactured by NXP USA Inc. It is specifically engineered for static or multiplexed liquid crystal displays containing up to eight backplanes and 46 segments. The device serves as a low-power single-chip controller and driver solution for alphanumeric character generation in vehicle electronics.

Display Drivers Replacement Considerations

The PCF8537AH is the industrial-grade equivalent within the same family. Verify if the industrial temperature range suffices for the application instead of the automotive-grade PCA8537AH.
