摘要 |
A time delay circuit for generating a dead time for a high-side/low-side transistor pair. A four transistor comparator circuit is employed with an input voltage reference transistor and output current reference transistor, and with a single capacitor determining the total time delay between the turn on of one of the output power devices and the turn off of the other. The time delay is closely related to the capacitance value (within 10%); power dissipation is minimized; the circuit is reduced to six transistors, and the time delay (or "dead time") can be accurately and easily programmed by the user.
