Overview

The LB1967M is a brushless motor driver IC for 2-phase half-wave drive well suited for compact fan motor for communication and office equipment, etc.

Features

• Dual power supply voltage design (5/12V) and wide voltage handling range

• Built-in Hall amplifier with hysteresis (supports core without auxiliary electrode)

• Built-in lockup protection and automatic recovery circuits (External capacitor for rotation detection need only be 0.1 µF, allowing compact, cost-saving design)

• Built-in FG output (Vosat = 0.2Vtyp at IO = 5 mA)

• Built-in output transistor with output withstand voltage 24Vmin/output current 500 mA (average), 1.2A (peak)

• Built-in thermal protection circuit

• Compact, high-temperature resistant MFP-10 package reduces external parts count and mounting space, therefore making this IC support the motors with a wide range of sizes and speeds.
