LB1867M
Overview
- 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 across Z1 - 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
- Built-in thermal shutdown
