LB1960M
Monolithic Digital IC
For Fan Motor
2-phase Half-Wave Driver
Overview
The LB1960M is a 2-phase half-wave driver for fan motor. The LB1960M is a compact package (MFP8). Low external
parts count, easy wiring, and small PCB area allow use also with miniature fan motors.
Functions
• Dual power supply voltage design (5/12V) and wide voltage handling range.
(3V also supported for rotation functions only)
• Constant-voltage Hall bias power supply (1.3V across HB to GND) assures stable Hall output over entire temperature
and power supply voltage range. External limiting resistor not required.
• Built-in Hall amplifier with hysteresis (supports core without commutating pole).
• Built-in lockup protection and automatic recovery circuits (External capacitor for rotation detection need only be 0.1µF,
allowing compact, cost-saving design).
• Built-in output transistor with output withstand voltage 24V (max)/output current 500mA (average), 1A (peak).
• Built-in thermal protection circuit.
