HVC4223F-B6 – TDK MICRON

The TDK HVC4223F-B6 is a single-chip flex servo-drive IC designed for brushless DC motor control in automotive applications. It integrates a 32-bit ARM Cortex-M3 microcontroller core with embedded flash memory and SRAM, enabling complex control algorithms to be implemented directly on the chip. The device features six integrated MOSFET gate drivers capable of driving external N-channel MOSFETs in a three-phase bridge configuration, supporting motor voltages up to 42V. Integrated safety features include overcurrent protection, overvoltage protection, undervoltage lockout, and overtemperature protection. Communication interfaces include CAN, LIN, and SPI, facilitating integration into automotive networks. The HVC4223F-B6 also incorporates analog peripherals such as ADCs for current and voltage sensing, and PWM generators for precise motor control. Its flexible architecture allows for sensorless or sensored motor control strategies.
