Manufacturer: Description:allowed to rise, linearly, as this capacitor is charged by a constant current source. Output overload pro- tection is provided in the form of a current limiter. The load current is sensed by an internal metal resistor connected to a comparator. When the load current exceeds a preset threshold this comparator sets a flip flop which disables the output stage and discharges the soft start capacitor. A second com- parator resets the flip flop when the voltage across the soft start capacitor has fallen to 0.4V. The output stage is thus re-enabled and the output voltage rises under control of the soft start network. If the overload condition is still present the limiter will trigger again when the threshold current is reached. The average short circuit current is limited to a safe value by the dead time introduced by the soft start network. The thermal overload circuit dis- ables circuit operation when the junction tempera- ture reaches about 150C and has hysteresis to prevent unstable conditions. |
