BA6286 - Reversible motor driver

FInput / output circuits 433 Motor driver ICs BA6286 / BA6286N FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 9V, VM = 9V, VREF = 9V) FMeasurement circuit 434 Motor driver ICs FCircuit operation (1) Input section The four output modes are controlled by two logic input

• 1) Logic and power sections have separate ground pins; this allows the IC to drive speed-variable, reversible motors by connecting an electronic governor circuit. 2) Built-in power saving circuit suppresses the stop mode current dissipation. FAbsolute maximum ratings (Ta = 25_C) 3) Output voltage can be set arbitrarily with the VREF pin. 4) Interfaces with TTL devices. 5) Built-in thermal shutdown circuit.
