Abusing a 555.
Does anyone have any application examples of the 555 with the source/sink
O/P used to drive the timing resistor and the discharge transistor driving the external load? The project is a 555 pulse generator with a complementary pair MOSFET O/P buffer, it will run from any wall wart over 12V that could potentially exceed the 555 ABS-MAX Vcc, so the 555 will have a simple resistor/zener regulator, the Vdd for the MOSFETs will be the full unregulated rail so the source/sink output won't go high enough to cut off the P-channel MOSFET. Thanks. |
