Overview

Ordering number : ENA2078 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).
• 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.

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded.
