Sanken SX68205M
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
