TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC

Toshiba 

TA8423P/F

VRF is feed back voltage generated by RF and output current of IL, drive current of ID and internal

reference circuit current of IR.

But IO and IR are negligible therefore,

IR << IL + ID

VRF ≈ RF (IL + IO + IR)

IL >> ID, IR

VRF ≈ RF·IL

0 Torque state is obtained when less than 2.3 V of control voltage fed into input terminal.

0 Torque state also obtained by select a stop mode by controlling FRS input (Pin (4)).

Less supply current is obtained with this condition.

2. FRS CIRCUIT

Forward, Reverse and Stop Modes are selectable by controlling this terminal.

Specified voltages are less than 1.3 V (Forward), 2.4~3.0 V or Open (Stop) and 3.9 V~VCC (Reverse).

VFRS − IFRS characteristic is shown below.
