TDK-Micronas
Embedded motor controller with 2 A peak current
TDK Corporation expands its 'Micronas HVC' embedded motor controller family with the 'HVC 5223C', a fully integrated motor controller with automotive grade 1 qualification for driving small BLDC and BDC motors with a peak phase current of 2 A.
The motor controller from TDK is manufactured in a compact 5x5 mm2 24-pin QFN housing. Functionality and pin assignment are compatible with the 'HVC 5222C', which can supply 1 A peak phase current. In addition to the ability to drive 1 A or 2 A peak current, the two components offer many motor-specific analog and digital functions, such as phase comparators, a virtual star point and current measuring amplifiers. This enables sensor-based and sensorless control of a single BLDC motor, H-bridge control of up to two BDC motors and the drive of various other loads.
The HVC family, including 'HVC 4x' and 'HVC 5x', has been extended to seven fully integrated motor controllers with three to six motor outputs capable of delivering peak currents from 500 mA to 2 A.
