Output high voltage setting
This function optionally sets output voltage by the output high voltage setting pin and controls the motor rotating speed.
However, when the output high voltage is set to a low level, consumption at IC increases. Carry out thermal design with
sufficient margin incorporated with the power dissipation (Pd) under the actual application condition taken into account.
a) BA6287F, BA6285FS, BA6285AFP-Y
The circuit diagram associated with the output high voltage setting
VREF pin is as per shown on the right. The output high and low
voltages V OH and V OL are expressed by:
V OH = VREF - ( V SAT(Q1) + V F(Q2) )
V OL = V SAT(Q3)
(Reference values; V SAT ≈ 0.15V, V F ≈ 0.7V)
In addition, the relation of VREF voltage to output voltage is expressed by:

(GND, BA6287F)
( V SAT(Q1) + V F(Q2) ) < VREF < VM - V SAT(Q2) + V F(Q2) + V SAT(Q1)
Therefore, when the VREF voltage condition is as follows, the
output high voltage is restricted.
VREF > VM - V SAT(Q2) + V SAT(Q1) + V F(Q2)
V OH = VM - V SAT(Q2)

VREF < VCC - V SAT(Q1) - V F(Q4) - V F(Q5)
VREF < VM - ( V SAT(Q2) + V F(Q3) ) + ( V F(Q2) + V F(Q3) ) - ( V F(Q4) + V F(Q5) ) (BA6956AN)
VREF < VM - V SAT(Q3) + ( V F(Q2) + V F(Q3) ) - ( V F(Q4) + V F(Q5) ) (BA6920FP-Y)
When the VREF voltage condition is as follows, the output high voltage is restricted.
VREF > VCC - V SAT(Q1) - V F(Q4) - V F(Q5)
VREF > VM - ( V SAT(Q2) + V F(Q3) ) + ( V F(Q2) + V F(Q3) ) - ( V F(Q4) + V F(Q5) ) (BA6956AN)
VREF > VM - V SAT(Q3) + ( V F(Q2) + V F(Q3) ) - ( V F(Q4) + V F(Q5) ) (BA6920FP-Y)
V OH = VCC - V SAT(Q1) - V F(Q2) - V F(Q3)
V OH = VM - V SAT(Q2) - V F(Q3) (BA6956AN)
V OH = VM - V SAT(Q3) (BA6920FP-Y)
