HT-DV40H
8 – 29
IC2 VHIAT5669H++1 : 5 CHANNEL MOTOR DRIVER (AT5669) (2/2 )
PIN DESCRIPTION
Notes: The indicated polarities for the output pins are under the condition that all inputs are (+).
The power supplies for the driver output are Vcc1 for the loader, Vcc2 for focus and tracking
drivers, and Vcc for pre-block and sled driver. Therefore, make sure Vcc1†Vcc2.
