Motor Drivers for Control of BLDC, BDC, or Stepper Motors

Release Note: Revision bars indicate significant changes compared to the

HVC 4222F-D2 Data Sheet.

1. Introduction

The HVC 4x family contains a group of highly integrated, intelligent embedded BLDC

motor and stepper motor drivers for direct 12V-battery operation with six integrated half-

bridges. All modules to directly drive PMSM, BLDC, or stepper motors are on chip. The

Interrupt Controller (NVIC). The Integrated Circuit (IC) features a debug interface, timers/

counters, capture compare units, a multichannel A/D converter with integrated program-

mable gain amplifier, an advanced LIN-UART with a LIN 2.x compliant physical layer, lin-

ear temperature sensors, Back Electromotive Force Comparators (BEMFC), and PWM-

controlled motor output (MOUT) ports with diagnostic functions for Permanent Magnet

Synchronous Motors (PMSM), Brushless Direct Current (BLDC) motors, brush-type DC

(BDC) motors or bipolar- and 3-phase stepper motor control. The computation capacity

supports complex motor control algorithms such as Space Vector Modulation (SVM) for

PMSMs. The hardware supports voltage controlled or current regulated bipolar stepper

motor control for full-stepping, half-stepping and micro-stepping mode.

The integrated digital and analog features reduce the number of necessary external

components to a minimum. Different operating modes make it possible to minimize the

current consumption according to the system needs.

The HVC 4x family features a flash program memory with a size of 32 KB or 64 KB, pro-

viding high flexibility in code development, production ramp-up, and in-system re-pro-

grammability. The 64 KB version contains an MPU for memory protection. Grade 1 and

high-temperature applications up to 160 °C junction.
