Product Details

Description



Features:

• Output protection Zener diode with variable withstand voltage
Z1, Z2 pins open: VOLM = 57V (24V specification)
Z1, Z2 pins shorted: VOLM = 32V (12V specification)
External Zener diode connected between Z1 and VCC
pins: support for fans with large drive current
• External resistor allows configuration for 12V or 24V.
• Direct Hall element connection possible (built-in Hall amplifier with hysteresis supports core without auxiliary electrode)
• Built-in output transistor with 1.0A output current (strengthened negative-current support for core without auxiliary electrode)
• Built-in rotation detection function: Low during rotation and High during stop
• Built-in lockup protection with automatic recovery
• ST pin for motor stop/drive (for standby mode of copiersetc.)
• FG output pin for rotation detection
• BC pin for kickback noise reduction (with 2 external capacitors)
• Built-in thermal shutdown
