TDK releases new embedded motor controller for driving BLDC and BDC motors

July 24, 2023 /SemiMedia/ -- TDK Corporation announces the expansion of its Micronas embedded motor controller series HVC with the HVC 5223C, an Automotive Grade 1 qualified, fully integrated motor controller to drive small brushed (BDC) or brushless (BLDC) motors with a peak phase current of 2 A.

The HVC 5223C comes in a compact 5x5 mm2 24-pin QFN package and is functionally and pin compatible with the HVC 5222C with 1 A peak current. Samples are now available for customer evaluation.

In addition to the ability to drive 1 A or 2 A peak current, the HVC 5222C and HVC 5223C devices offer many motor-specific analog and digital functions, such as phase comparators, a virtual star-point and current sense amplifier to enable sensor-based and sensor-less control of a single BLDC or up to two BDC motors and driving of various other loads.

The HVC family, including HVC 4x and HVC 5x, has now expanded to seven fully integrated motor controllers with three to six motor outputs capable of delivering from 500 mA to 2 A of peak currents. All devices feature a 32-bit ARM® Cortex®-M3 CPU core and 32 KB or 64 KB Flash Memory options. Additionally, all devices are equipped with a 12-bit, 1-µs ADC for various measurements, making them versatile options for applications requiring accurate sensing. They also come equipped with a LIN transceiver and UART for communication and auto-addressing* using the BSM method, which adds to their versatility in various applications.

All HVC devices are automotive qualified according to AEC-Q100 for temperature Grade 1, making them a solution for compact automotive actuator applications primarily targeted at HEV/EV thermal systems. The AEC-Q100 qualification ensures that the HVC 5223C meets the highest standards of quality and reliability, making it a trusted choice for automotive and industrial applications.
