PCA9452AHNK

Power Management - Specialized Overview

The PCA9452AHNK is an automotive-grade Power Management IC (PMIC) designed for i.MX 93x family processors. It integrates six high-efficiency step-down regulators, five LDOs, a 400 mA load switch, and a 32.768 kHz crystal oscillator driver. Key buck regulators support Dynamic Voltage Scaling (DVS), remote sensing, and dual-phase operation. The device operates within a -40 °C to 105 °C ambient temperature range and complies with AEC-Q100 Grade 2 standards.

Power Management - Specialized Feature Summary

• Integrates six high-efficiency step-down regulators with DVS and remote sense capabilities
• Includes a dedicated low-quiescent current LDO for secure non-volatile storage power
• Features a built-in 2-bit bidirectional voltage level translator for I²C interfaces
• Provides a 400 mA load switch with active discharge resistor for peripheral power management

Power Management - Specialized Applications

• Primary power supply for NXP i.MX 93x application processors in automotive systems
• Powering DRAM memory modules within automotive infotainment or instrument clusters
• Supplying regulated power to SD cards via integrated load switch
• Driving 32.768 kHz real-time clock oscillators in vehicle electronics

Power Management - Specialized Procurement Notes

Verify the specific suffix 'HNK' against official NXP documentation to confirm package type and tape/reel specifications. Ensure compatibility with the target i.MX 93x processor variant. Confirm that the AEC-Q100 Grade 2 qualification meets your automotive system requirements. Check for any required external components for stability of the buck regulators and LDOs as specified in the datasheet.

Power Management - Specialized Selection Notes

Select this component when designing automotive applications requiring a single-chip solution for i.MX 93x processors. It is suitable for environments demanding AEC-Q100 Grade 2 reliability. Consider its integrated features such as DVS and remote sensing if board-level IR drop compensation is needed. Evaluate the thermal performance given the integration of multiple regulators in the HVQFN-56 package.

Power Management - Specialized Part Context

The PCA9452 series serves as the primary PMIC for NXP's i.MX 93x automotive application processors. It consolidates multiple power rails into a single chip, reducing board space and complexity. The product is part of NXP's Product Longevity program, ensuring supply assurance for a minimum of 15 years after launch.
