Silicore. com. cn CHMC 5/6 Silicore D5954 NOTES ON USE 1. Thermal-sh ut-down circuit built-in. In case IC ch ip temp erature rise to 175°C(typ.), thermal-shut-down circuit operates and ou tput current is mu ted. Next time IC chip temperature falls bellows 150°C(typ.), the driver blocks start. 2. In case stand-by-pin voltage und er 0.5V or opened, quiescent cu rrent is muted. Stand-by-pin voltage should be over 2.0V for normal application. 3. In case supply voltage falls below 3.5V (typ.), output current is mu ted. Next time supply voltage rises to 3.7V(typ .), the driver blocks start. 4. Bias\pin (pin 27 ) sh ou ld be pu lled u p mo re than 1.2V. In case bias-pin voltage is pulled down under 0.9V (typ .), output current is mu ted. 5. Insert the by-pass capacito r between Vcc-pin and GND-pin of IC as possible as near (approximately 0.1µF). 6. Heat dissipation fins are attached to the GND on the inside of the package. Make sure to connect these to the external GND. 7. Output pin is to avoid short-circuit with Vcc, GND and other output pins. And, be fully careful in the direction of an integrated circuit when you put an integrated circuit. On the su bstrate. An integrated circuit is da maged, and smoke may co me out by the case. ※ Output pin …11~18pin Vcc…8pin, PVcc1…9pin, PVcc2…21pin PreGND…22pin, PGND…10,19pin CHARACTERISTIC CURVES Pd (W) 3 2 1 0 0 25 50 75 100 125 150 Ambient temperature Ta (°C) Pd : p ower d issip atio n * On less than 3%(percentage occupied by copper foil), 70×70 mm 2 , t = 1 . 6 mm, g l a s s epoxy mounting.
