LT1158  
Half Bridge N-Channel  
Power MOSFET Driver  
FEATURES  
DESCRIPTION  
+
A single input pin on the LT®1158 synchronously controls  
two N-channel power MOSFETs in a totem pole configura-  
tion. Unique adaptive protection against shoot-through  
currents eliminates all matching requirements for the two  
MOSFETs. This greatly eases the design of high efficiency  
motor control and switching regulator systems.

A continuous current limit loop in the LT1158 regulates  
short-circuit current in the top power MOSFET. Higher  
start-up currents are allowed as long as the MOSFET V  
does not exceed 1.2V. By returning the FAULT output to  
the enable input, the LT1158 will automatically shut down  
in the event of a fault and retry when an internal pull-up  
current has recharged the enable capacitor.

APPLICATIONS  
An on-chip charge pump is switched in when needed to  
turn on the top N-channel MOSFET continuously. Special  
circuitry ensures that the top side gate drive is safely  
maintained in the transition between PWM and DC opera-  
tion. The gate-to-source voltages are internally limited to  
14.5V when operating at higher supply voltages.
