LB11862MC
Fan Motor Driver,
Single-Phase, Full-Wave
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.
Features
Single-phase full-wave drive
Built-in thermal shutdown circuit.
Built-in lock protection and automatic recovery circuits
Typical Applications
PC power supply system
CPU cooling fan system
Refrigerator
PC

1. Stresses exceeding those listed in the Absolute Maximum Rating table may damage the
device. If any of these limits are exceeded, device functionality should not be assumed,
damage may occur and reliability may be affected.
2. Specified circuit board : 114.3 76.1 1.6mm3, glass epoxy
3. Absolute maximum ratings represent the values which cannot be exceeded even for a
moment
4. If you should intend to use this IC continuously under high temperature, high current, high
voltage, or drastic temperature change, even if it is used within the range of absolute
maximum ratings or operating conditions, there is a possibility of decrease reliability. Please

1. D1 is for protection against breakdown in case of reverse connection of power supply and mat is deleted when there
is no problem.
2. C2 is necessary to allow the kick-back regenerative current to flow when C2 is to be used with the coil current of
500mA or more.
3. CT to be connected to GND when not used.
4. RD, ST and HB pins to be OPEN when not used.
