TDK Corporation expands its Micronas HVC embedded motor controller family with the fully integrated family members HVC 5222D and HVC 5422D for driving brushless (BLDC), brushed direct current (BDC) and stepper motors.

The devices bring significant improvements over the popular HVC 5221D by doubling the drive current and SRAM and quadrupling the EEPROM while still ensuring pin compatibility. Sample customer evaluations are now available. Series production is planned for the first quarter of 2025.

The latest models of embedded motor controllers, HVC 5222D and HVC 5422D, feature expanded flash memory of 32 KB and 64 KB, respectively, and support currents up to 1 A for BLDC and stepper motors and up to 2 A for DC motors. They offer advanced motor-specific features such as current programming for micro-stepping, integrated zero point detection, virtual star point and integrated shunts for sensor-based and sensorless motor control, meeting the ISO 26262 standard for ASIL applications.

The HVC family has now been expanded to include nine fully integrated motor controllers with three to six motor outputs that can deliver peak currents from 500 mA to 2 A. All devices have a 32-bit Arm Cortex-M3 CPU core and either 32 KB or 64 KB flash memory. Equipped with a 12-bit, 1 μs ADC, these devices enable seamless integration of TDK Hall and TMR sensors.

In addition, the devices feature a LIN transceiver and UART for communication and support auto-addressing using the bus shunt method (BSM), which further increases their versatility in various applications. PWM control via the LIN pin is also supported. Certified to AEC-Q100 automotive standards for temperature class 1, all HVC devices ensure reliability and cover automotive and industrial applications with power requirements up to 30W.
