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.

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
