Motor driver ICs

BA6825FS / BA6826FS

FInput / output circuits

(1) Hall and ECI inputs

(2) Coil output

FCircuit operation

(1) The signal from the Hall device is amplified by the

Hall amplifier and then supplied to the driver circuit. The

driver gain, which is constant, is regulated by changing

the Hall amplifier gain with the input current on the output

current control pin (E^CIpin). The motor rotational speed

is sensed by the FG, and the output of which is F / I-con-

verted and supplied to the E^CIpin as a feedback signal,

so that a constant rotational speed is maintained as fol-

lows :

(2) WhenthevoltageonHallINφ¹())ishigherthanthe

voltage on Hall INφ¹(*), an output current flows from

OUT1(*)toOUT1())accordingtothevoltagedifferen-

tial. When the voltage on Hall INφ¹(*) is higher, on the

other hand, an output current flows from OUT1 ()) to

OUT1 (*).

Similarly, whenthevoltageonHallINφ²())ishigherthan

the voltage on Hall INφ²(*), an output current flows from

OUT2(*)toOUT2())accordingtothevoltagedifferen-

tial. When the voltage on Hall INφ²(*) is higher, on the

other hand, an output current flows from OUT2 ()) to

OUT2 (*).

(1) The motor speed decreases.

(2) The speed control IC outputs a feedback signal to the

ECI pin.

(3) The Hall amplifier gain increases.

(4) The output current increases.

(5) The motor speed increases.
