Sinusoidal 3-phase Brushless Motor Drivers with Sensorless Vector Control
SX68200M Series
Data Sheet
Description
The SX68200M series are 3-phase brushless motor drivers in which output transistors, pre-drive circuits, bootstrap diodes with current-limiting resistors are highly integrated. Employing a sinusoidal driving strategy with a sensorless vector control, the SX68200M series brings a small-sized, high-efficient, and low-noise motor controlling into your application.
These products can run on a 3-shunt current detection system and optimally control the inverter systems of medium-capacity motors that require universal input standards.
Features
● Pb-free (RoHS Compliant) ● Sinusoidal Current Waveform (Low Noise, High
Efficiency) Sensorless Vector Control (High Efficiency at Load Variation, Small Size) ● Built-in Bootstrap Diodes with Current-limiting Resistors ● EEPROM as a Control Parameter Storage ● Two Speed Control (PI Control) Modes:
- Analog Voltage Control (VSP Pin) - Serial Communications Control (I2C Compatible)
● 3-shunt Current Detection ● DIAG Pin Fault Signal Output ● Protections Include:
- V3 Pin Undervoltage Protection - Watchdog Timeout Detection - Memory Error Detection - Overvoltage Protection and Undervoltage Lockout
for Main Power Supply (VM Pin) - Soft Overcurrent Protection - Hard Overcurrent Protection - Thermal Warning - Thermal Shutdown - Undervoltage Lockout for Logic Supply - Loss-of-Synchronization Protection
