FAN8082D
Bi-directional DC Motor Driver
Features
• Built-in brake function for stable brake characteristics.
• Built-in element to absorb a surge current derived from
changing motor direction and braking motor drive.
• Motor speed control by an external voltage.
• Stable motor direction change.
• Interfaces with CMOS devices.
• Built-in the thermal shut down circuit (165°C).
• Low standby current. (6.5mA)
Description
The FAN8082D is a monolithic integrated circuit designed
for driving bi-directional DC motor with braking and speed
control, and it is suitable for the loading motor driver of
VCR, CDP, and TOY systems. The speed control can be
achieved by adjusting the external voltage of the speed
control pin. It has two pins of logic inputs for controlling the
forward/ reverse and braking.
8-SOP-225
Typical Applications
• Compact disk player (CDP) tray or changer
• Low current DC motor such as audio or video equipment.
• General DC motor

NOTES:
1. Duty 1 / 100, pulse width 500µs
2. 1) When mounted on glass epoxy PCB (76.2 × 114 × 1.57mm)
2) Power dissipation reduces 2.64mW / °C for using above Ta=25°C.
3) Do not exceed Pd and SOA(Safe Operating Area).

This circuit define reference voltage of output.
When pin #4 is “H” and pin #5 is “L”,
- V1 = Vzd + VbeQ4 + VbeQ5 ·=· 8.9V
- V2 = Vbeq 7 + VsatQ6 ·=· 0.87V
V1 and V2 are related with the output voltage of the motor and change according to the voltage of pin #3 (VCTL).
