TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC

Toshiba 

APPLICATION CIRCUIT

TA8423P/F

Note 1: Recommendable value of RF is 0.3 to 5 Ω. It depends on required initial torque, gain, coil impedance and

control voltage of Pin 5.

Note 2: To connect directly to IC Pin (Fin for F version and (13) Pin for P version) and GND to eliminate the influence

of common impedance.

It is required to increase the value of this capacitance for stable operations in case of poor wiring or

patterning of PCB.

Note 3: Special care should be taken not to have a common impedance with GND line, RF GND line and Hall Sensor

GND line.

Note 4: Please select to optimum value for eliminate a vibration noise and parasitic oscillation. And also to change

the connection (for example, each output to VCC or to RF) for getting better characteristics.

Note 5: Utmost care is necessary in the design of the output line, VCC and GND line since IC may be destroyed due

to short−circuit between outputs, air contamination fault, or fault by improper grounding.
