LB1862MC
Monolithic Digital IC
For Fan Motor
Single-Phase Full-Wave Driver
Overview
Single-phase full-wave drive design and a compact package make these ICs optimal for small fans (especially CPU
cooling fans). Low switching noise and effective motor drive are further advantages.
Functions
• Support for 5V/12V dual power supply voltage
• Built-in regenerative circuit allows use of reverse connection protection diode
• Built-in Hall amplifier with hysteresis (supports core without auxiliary electrode)
• Built-in lockup protection and automatic recovery circuits
• Latch-type lockup detection output (RD) is Low during rotation and High during stop
• Hall bias pin and start/stop pin allow reduced current drain in standby mode
• 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. Please contact us for the further details.
