FOperation notes

(1) Power save

The power save input is an input / output circuit as

shown in Fig.1. The power save pins have a thermal der-

ating characteristic of *8mV / _C. The resistance also

has a fluctuation of ±30%, so be careful of the input volt-

age range.

(2) Reverse

The reverse input is an input / output circuit as shown in

Fig.2. The reverse pins have a thermal derating charac-

teristic of *7mV / _C. The resistance also has a fluctua-

tion of ±30%, so be careful of the input voltage range.

(3) Hall input

The Hall input is an input circuit as shown in Fig.5. The

Hall elements can be connected in series or in parallel.

BA6848FP / BA6853FS

(4) Thermal shutdown (TSD)

When the junction temperature reaches 175_C (Typ.),

the A1 to A3 coil outputs become open. There is an

approximate 15_C (Typ.) temperature hysteresis.
