TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic

Toshiba 

Application Notes (example 2)

TB62725P/F/FN application circuit (for VLED > 17 V)

Example: An unnecessary voltage in the case of VLED > 17 V makes a voltage descend by the Zener diode.

TB62725P/F/FN

Example: TD62M8600F 8-bit multi-chip PNP transistor

array, which is not used in static lighting

system.
