LB1960MC
Monolithic Digital IC
For Fan Motor
2-phase Half-Wave Driver
Overview
The LB1960MC is a 2-phase half-wave driver for fan motor. The LB1960MC is a compact package. 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).
