The HVC 5481G from TDK Corporation is an Automotive-Qualified Motor Controller IC that has been designed to drive brushless DC (BLDC), brushed DC (BDC), and stepper motors. It requires an input voltage of 6-18 V and an input current of 15 mA (peripherals). This motor controller has been designed to enable smaller size, lower cost, and a lower number of external components compared to the HVC 4x line-up of controllers. It consists of an ARM Cortex-M3 CPU with built-in 2/4 KB SRAM, 64 KB Flash, and 256 Byte NVRAM, input generators, timers, oscillators, voltage regulator, A/D converter, D/A converter, sensors, protection and diagnostics, and interfaces. This AEC-Q100 Grade 1-qualified controller uses 12-bit pulse width modulation (PWM) generators with center- and edge-alignment waveforms at the input to drive the motors.
This motor controller also incorporates other input drive capabilities such as differential input channels, digital timers, capture-compare units, and SPI master interface for more precise motor control and development of application functions. It also includes GPIO ports for application interfaces and a LIN transceiver interface that can be used for evaluating the controller using HVC 5x application boards. The boards can be configured using solder jumpers to drive different types of motors. This controller is equipped with software packages for remote configuration and control. It is available in a thermally-efficient surface-mount package that measures 5 x 5 mm.
