8CH HIGH CURRENT SOURCE DRIVER

Toshiba 

Duty (when duty = 20%)

Condition : pulse width = 32 µs (cycle = 1280 µs)

Duty = (32 µs × 8ch) ÷1280 µs = 20%

APPLICATION CIRCUIT

Note 1: TOSHIBA recommends external resistor REXT (approx. 0.9 Ω / 2W) be connected between VCC2 and VC.

PRECAUTIONS for USING

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, VCC (VCC1, VCC2, VC) and GND line since IC may be

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