Is it possible to use this to drive the mosfet’s? The local driver bypass capacitor is too large. The ICL is a dual monolithic high-speed driver designed to convert TTL level signals into high current outputs at voltages up to 15V. Then the reply came as.. Thx for your inputs.. Ypu could have several volts appearing on top of the Vdd voltage. You should also follow the guidelines about return path routing as the hot loop in this IC can cause unwanted common impedance.
