MPF9453AVMB1HN

Overview

The MPF9453AVMB1HN is a specialized Power Management IC (PMIC) designed for the i.MX 91 processor and simple Linux platforms. It integrates four high-efficiency step-down regulators, three Low Dropout (LDO) regulators, one 400 mA load switch, and a 32.768 kHz crystal oscillator driver. The device operates within a supply voltage range of 2.7V to 5.5V and supports an industrial operating temperature range of -40°C to +105°C. It is housed in a 40-pin HVQFN package measuring 5.0 mm x 5.0 mm with a 0.4 mm pitch.

Feature Summary

• Integrates multiple power rails including buck regulators, LDOs, and a load switch on a single chip
• Includes a dedicated crystal oscillator driver for real-time clock functionality
• Optimized for low power consumption and cost-effective implementation in IoT applications

Applications

• i.MX 91 processor power supply solutions
• Simple Linux platform power management
• IoT device power regulation

Procurement Notes

Verify the specific suffix (e.g., AVMA vs AVMB) against your Bill of Materials, as packaging and reel specifications may vary between variants. Confirm availability status directly with NXP or authorized distributors, as stock levels are subject to change. Ensure the selected variant matches the required thermal and electrical specifications for your target application environment.

Selection Notes

Select this component when designing systems based on the i.MX 91 processor that require a consolidated power solution. It is suitable for applications needing multiple regulated voltages from a single input source. Consider the 40-pin HVQFN package constraints for PCB layout and thermal dissipation requirements during the design phase.

Part Context

This part belongs to the PF9453 series of PMICs from NXP Semiconductors. These devices are specifically engineered to support the power sequencing and rail requirements of NXP's i.MX 91 application processors. The series aims to reduce component count and board space by integrating essential power management functions into a single compact package.

Replacement Considerations

Check for other variants within the PF9453 family, such as MPF9453AVMA1HN or MPF9453AVMA2HNR2, which may offer different packaging options like tape-and-reel versus tray. Verify pin-to-pin compatibility and electrical parameter equivalence before substituting.
