mc34151 ON Semiconductor, mc34151 Datasheet - Page 8

• Manufacturer Part Number: mc34151
• Description: High Speed Dual Mosfet Drivers
• Manufacturer: ON Semiconductor

In noise sensitive applications, both conducted and radiated EMI can
be reduced significantly by controlling the MOSFET’s turn−on and
turn−off times.

The capacitor’s equivalent series resistance limits the Drive Output Current
to 1.5 A. An additional series resistor may be required when using tantalum or
other low ESR capacitors.
