HVC4223F

Overview

The HVC4223F is a high-voltage embedded motor controller from the Micronas HVC 4x family, designed for automotive smart actuators. It integrates a 32-bit Arm Cortex-M3 core with 32 KB Flash and 2 KB SRAM. The device features six integrated N-channel MOSFET half-bridges with charge pumps, supporting direct drive of BLDC, PMSM, or stepper motors. Operating voltage ranges from 5.4 V to 18 V with 40 V load-dump resistance. Key peripherals include enhanced PWMs, three BEMF comparators, LIN 2.1 interface, SPI master, and multiple timers.

Feature Summary

• Integrates a 32-bit Arm Cortex-M3 microcontroller core with on-chip memory and debug interfaces.
• Features six fully integrated N-channel MOSFET half-bridges with charge pumps for direct motor driving.
• Includes advanced motor control peripherals such as enhanced PWMs and high-voltage back-EMF comparators.
• Supports automotive networking via a LIN 2.1 compliant physical layer interface.

Applications

• HVAC flap actuators
• Remote smart actuators
• Small electric motor drives in automotive systems

Procurement Notes

Verify the specific suffix (e.g., -D2) against the official datasheet to confirm package type and temperature range. Ensure the application requires six motor outputs, as this model is part of the HVC 4x family optimized for that configuration. Cross-reference the ordering code with TDK-Micronas documentation to avoid confusion with the HVC 5x series.

Selection Notes

Select the HVC4223F when a single-chip solution for six-motor-output applications is required. It is suitable for replacing conventional mechanical drives with electric ones in compact designs. Consider the HVC 5x family if fewer outputs or smaller form factors are needed. Verify compatibility with the target motor type, including BLDC, PMSM, or stepper configurations.

Part Context

The HVC4223F belongs to the Micronas HVC 4x flex servo-drive family, a series of fully integrated motor drivers for automotive small motor applications. This family has shipped over 200 million devices and serves as a keystone in TDK-Micronas' portfolio. The HVC 4x line offers a one-size-fits-all approach for driving various motor types using six outputs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. For applications requiring fewer than six outputs or different power levels, consider the HVC 5x family variants such as the HVC 5221D or HVC 5481G, which offer lower cost and form factor options.
