Technical content

The AN8377N is an IC which incorporates 3 circuits of BTL drivers for driving various DC motors such as actua- tors (focus, tracking, traverse), spindles, and loading of the CD players, and the +5V low drop type power supply. n Features

• Operating supply voltage range ; VCC =5.5V to 18V
• Built-in 3 circuits of voltage BTL drivers (maximum drive current : 500mA)
• Stable circuit operation against supply voltage change and temperature change due to the built-in stabilized power supply
• Built-in +5V low drop power supply (external PNP power transistor)
• Built-in reset circuit (reset voltage : 4.82V)
• Built-in thermal protective circuit (operating tempera- ture : 159 ; typ.)
• Built-in power cut circuit (motor driver 1 only) n Applications Linear driving of the DC motors and actuators of the CD players, CD radio cassette tape recorder, and so on.
