EL7761

100V Half Bridge Driver

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.
