PCA2117DUGR/DAZ

Display Drivers Overview

The PCA2117DUGR/DAZ is a real-time clock (RTC) and battery switch controller manufactured by NXP USA Inc. It integrates a low-power RTC with an I²C interface, a programmable square wave output, and a battery backup switching circuit. The device ensures continuous timekeeping during main power loss by automatically switching to a connected backup battery. It features a dedicated interrupt pin for alarm or timer events and operates within a standard voltage range suitable for portable and embedded systems.

Display Drivers Feature Summary

• Integrates a real-time clock with calendar functionality and an I²C serial interface for system communication.
• Includes an automatic battery switch controller that manages power transition between main supply and backup source.
• Provides a programmable square wave output signal for peripheral synchronization or wake-up triggers.

Display Drivers Applications

• Portable consumer electronics requiring persistent timekeeping
• Embedded industrial control systems needing reliable clock sources
• IoT devices with low-power standby modes

Display Drivers Procurement Notes

Verify the specific suffix DAZ against official NXP documentation to confirm tape-and-reel packaging configuration. Ensure compatibility with the target I²C bus voltage levels and check for any regional compliance certifications required for the end application. Cross-reference the date code with current production status to avoid obsolete stock issues.

Display Drivers Selection Notes

Select this component when a combined RTC and power management solution is required to minimize board space. It is suitable for designs where maintaining accurate time during power outages is critical. Consider the package size and lead pitch if PCB layout constraints are tight compared to discrete RTC solutions.
