Power MOSFET Driver with Lossless Protection  
General Description  
Features  
Y
Built-in charge pump for gate overdrive of high side  
drive applications  
The LM9061 is a charge-pump device which provides the  
gate drive to any size external power MOSFET configured  
as a high side driver or switch. A CMOS logic compatible  
ON/OFF input controls the output gate drive voltage. In the  
ON state, the charge pump voltage, which is well above the

supply, is directly applied to the gate of the  
MOSFET. A built-in 15V zener clamps the maximum gate to  
source voltage of the MOSFET. When commanded OFF a  
110 mA current sink discharges the gate capacitances of  
the MOSFET for a gradual turn-OFF characteristic to mini-  
mize the duration of inductive load transient voltages and  
further protect the power MOSFET.
