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 D
SET
to
GND provides "dead time" programmability. Shorting D
SET
to V
DD
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.
