HVC4222F

Overview

The HVC4222F is an embedded motor controller from the Micronas HVC 4x family, designed for automotive small motor applications. It integrates an ARM Cortex-M3 core with 2 kbyte RAM and 32 kbyte flash memory. The device features six independent N-channel MOSFET half-bridge drivers capable of 500 mA output, operating within a voltage range of 5.4 V to 18 V with dual-mode 40 V load-dump resistance. It supports LIN 2.1 communication and includes a 12-bit multi-channel ADC, two 16-bit timers, and enhanced PWMs. The component operates at junction temperatures up to 160 °C and ambient temperatures up to 150 °C in a PQFN40 package.

Feature Summary

• Integrates six independent half-bridge drivers for direct control of brushed, stepper, or BLDC motors without external components
• Combines an ARM Cortex-M3 processor with on-chip memory and diagnostic peripherals for fully integrated system solutions
• Features built-in Hall-effect sensing technology for robust motor commutation and position detection
• Includes comprehensive protection mechanisms such as digital watchdogs, voltage supervision, and thermal monitoring

Applications

• Automotive electric window and sunroof actuators
• Thermal management systems including cooling fan and pump control
• Seat adjustment and positioning mechanisms
• Steering column and pedal actuation systems

Procurement Notes

Verify the specific ordering code against the manufacturer's current datasheet to ensure compatibility with required memory configurations and package variants. Confirm that the application environment stays within the specified ambient temperature limits of 150 °C and junction temperature of 160 °C. Check for any recent product lifecycle notifications regarding availability or recommended replacements for this specific part number.

Selection Notes

Select the HVC4222F when a design requires exactly six motor outputs driven by a single integrated controller. This part is suitable for applications needing high integration to reduce bill of materials cost and board space. Consider alternative HVC series members if fewer than six outputs are needed or if higher peak current capabilities beyond 500 mA per bridge are required for the specific motor load.

Part Context

The HVC4222F belongs to the established Micronas HVC 4x flex servo-drive family, which serves as a cornerstone for TDK-Micronas' integrated motor control portfolio. This family is distinguished by its ability to drive various motor types using a unified architecture. The HVC 4x series is specifically optimized for automotive environments, leveraging decades of expertise in combining CMOS technology with magnetic sensor integration for reliable operation under harsh conditions.

Replacement Considerations

HVC4422F offers extended memory and MPU support for RTOS requirements while maintaining similar driver capabilities.
