Description
The EL7761 provides a low cost solution to many half bridge applications. The EL7761 is DC coupled so that there are no start up problems associated with AC coupled schemes. A single resistor from DSET to GND provides "dead time" programmability. Shorting DSET to VDD gives the shortest delay (~100ns). The POL pin controls the polarity of the low side driver. The polarity of the upper driver is always inverting. The EN pin, when low, forces the high and low side outputs into their low state.
