The HVC 5222D from TDK Corporation is an Automotive-Qualified Motor Controller IC that has been designed to drive brushed DC (BDC), brushless DC (BLDC), and stepper motors. It requires an input voltage of 6-18 V and provides an output current of up to 1 A (BLDC and stepper motors) and 2 A (DC motors). This AEC-Q100 Grade 1-qualified controller consists of an ARM Cortex-M3 CPU with 4 KB SRAM and 32 KB flash, A/D converters, a D/A converter, BEMF comparators, serial interfaces, a voltage regulator, timers, protection circuitries, and diagnostics. It can be driven using a built-in 12-bit pulse width modulation (PWM) generator with center- and edge-alignment with ADC triggering. This IC also supports input triggering using other functionalities – differential input channels, digital timers, and capture-compare units, allowing precise motor control of TDK’s 2D/3D sensors.
This motor controller IC can communicate with evaluation boards via Hall Effect sensor feedback or BEMF sensing and also includes a LIN bus header with auto-addressing function. It is equipped with a demo board that can be configured by soldering jumpers to drive the motors using the integrated half bridges of the IC. This controller offers temperature diagnosis of individual blocks and pins to ensure safe operation. It also uses an 8-bit DAC to limit the motor current, further enhancing the safety during control. This IC is available in a thermally-efficient surface-mount package that measures 5 x 5 mm and has pins that are compatible with future devices.
