Output circuit with transistor overcurrent protection |
July 3, 2007 |
| When the overcurrent detection circuit detects that a voltage drop of the output transistor exceeds a threshold value, it turns on the switch by the first operational amplifier. In the shut-down signal generation circuit, the capacitor is charged with a charge current determined based |
