MCF8315A Overview
The MCF8315A provides a single-chip, code-free sensorless FOC solution for customers driving speedcontrolled 12- to 24-V brushless-DC motors (BLDC) or Permanent Magnet Synchronous motor (PMSM) up to 4-A peak current. The MCF8315A integrates three ½-bridges with 40-V capability and a low RDS(ON) of 240 mΩ (high-side + low-side FETs). MCF8315A integrates power management circuits including an voltage-adjustable buck...
