TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC

Toshiba 

APPLICATION CIRCUIT

TA8420,21AF

Note 1: There’s no requirement of this diodes in normal applications.

But if the VCC is more than 14 V or use large value of coil reactance, we recommend to connect this diodes.

Note 2: There’s no requirement of this capacitance in normal applications.

But connection 0.47~10 µF of this capacitance increases a stability of operation.

Note 3: This capacitance is for noise suppression use.

Connect if required.

Note 4: We recommend to connect capacitance between each output and GND (or out (A) and (B)), to suppress RFI

and noise problems.

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.

Note 6: In case of large mutual inductive value between La and Lb.

Diodes (or CR) are required to restrict parasitic oscillation caused by negative electro−motive force

generated by inductive mutual effect between La and Lb.
