mc34152 ON Semiconductor, mc34152 Datasheet - Page 9

• Manufacturer Part Number: mc34152
• 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.
