PRECAUTIONS for USING

(1)

This IC does not include built-in protection circuits for excess current or overvoltage.

If this IC is subjected to excess current or overvoltage, it may be destroyed.

Hence, the utmost care must be taken when systems which incorporate this IC are designed.

Utmost care is necessary in the design of the output line, COMMON and GND line since IC may be destroyed

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

(2)

When using TD62064P/AP/F/AF to drive an inductive load (such as a motor, solenoid, or relay), Toshiba

recommend you use diodes (pins 1 and 8) to absorb the counter electromotive force generated when driving an

inductive load.

When using TD62074P/AP/F/AF to drive an inductive load (such as a motor, solenoid, or relay), Toshiba

recommend you connect diodes externally to absorb the counter electromotive force generated when driving

an inductive load.
