UPD9975F1-CN9-A

Overview

The UPD9975F1-CN9-A is a Power Management IC (PMIC) manufactured by Renesas Electronics Corporation. It is designed specifically for mobile phone applications, providing efficient and reliable power control. The component operates within the Analog & Mixed Signal category and features a BGA package type. It is currently listed as an active product with RoHS compliance status noted as not applicable in some records, while others indicate lead-free status.

Feature Summary

• Specialized power management integrated circuit tailored for mobile communication devices
• Delivers efficient and reliable voltage regulation and power distribution control
• Designed to support complex power sequencing requirements in handheld electronics

Applications

• Mobile phones and smartphones
• Handheld communication devices
• Portable consumer electronics requiring compact power solutions

Procurement Notes

Verify the specific datasheet version and exact pinout configuration before integration, as legacy PMICs may have variant differences. Confirm RoHS compliance documentation directly with the manufacturer or authorized distributor, as records show conflicting status regarding lead-free certification. Ensure the BGA package handling procedures meet your assembly facility's capabilities for fine-pitch components.

Selection Notes

Select this component when designing power architectures for mobile handsets that require a dedicated PMIC solution from Renesas. Consider its compatibility with existing baseband processors and RF front-ends used in similar device generations. Evaluate the thermal performance of the BGA package against your enclosure constraints. Verify that the available output rails match the voltage requirements of your target subsystems.

Part Context

This part belongs to Renesas' portfolio of analog and mixed-signal products, historically significant in the mobile communications sector. As a PMIC, it integrates multiple power functions into a single chip to save board space. While newer generations exist, this model remains relevant for maintaining legacy mobile device production lines or repair markets where specific power management characteristics are required.

Replacement Considerations

Check for direct cross-reference numbers from Renesas or Rochester Electronics. Ensure any substitute maintains the same BGA footprint and pin compatibility. Verify that alternative PMICs offer identical voltage rails and current capabilities for mobile phone applications.
