ICs for Motor Control
The RAJ306000 is a motor control IC that can easily control three-phase brushless DC (BLDC) motors that are used in battery-operated power tools, drones, communication robots, cleaning robots, and so on. With its built-in high-function pre-drivers and RL78/G1F microcontroller (flash ROM: 64 KB) for motor control, the RAJ306000 drives a BLDC motor safely and at low power (high efficiency), facilitating BOM cost reduction and other requirements. It has the following features.
Features
Compact: Up to 50% size reduction*
Integrates innovative high-performance analog circuitry.
Efficient: Up to 35% motor drive power dissipation improvement*
500mA pre-driver includes proprietary performance optimization circuit.
Standard: Common platform from 6V to 30V
Double boost function enables platform reuse across motor voltages.
Sensor-less: High performance sensor-less motor drive control
Reliable operation for low to high speed.
