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). • 100V High Side Voltage 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. • 1MHz Operation FN7299 • Programmable Delay • Direct Coupled • No Start Up Ambiguity • Rail to Rail Output • Shutdown Function • 1.0 Amp Peak Current • Improved Response Times Pinout • Matched Rise and Fall Times EL7761 (16-PIN PDIP, SOIC) TOP VIEW • Low Supply Current • Low Output Impedance • Low Input Capacitance Applications • Uninterruptible Power Supplies • Distributed Power Systems • IGBT Drive • DC-DC Converters • Motor Control • Power MOSFET Drive • Switch Mode Power Supplies Ordering Information PART NUMBER EL7761 WAVEFORM EXAMPLE TEMP.
