Motor driver ICs
Reversible motor driver
BA6285FS / BA6285FP
The BA6285FS and BA6285FP are reversible-motor drivers with a maximum output current of 1.0A. Two logic inputs
allow four output modes: forward, reverse, stop (idling), and brake. A built-in power saving circuit suppresses current
consumption when the motor is in stop mode.

Applications
VCRs and audio equipment in general
F Features
1) Logic and power sections have separate ground
pins; this allows the IC to drive speed-variable, re-
versible motors by connecting an electronic governor
circuit.
2) Built-in power saving circuit suppresses the stop
mode current dissipation.
3) Output voltage can be set arbitrarily with the V
ref
pin.
4) Interfaces with TTL devices.
5) Built-in thermal shutdown circuit.
