LTC7060  
100V Half-Bridge Driver with Floating  
Grounds and Adjustable Dead-Time  
FEATURES  
DESCRIPTION  
The LTC®7060 drives two N-Channel MOSFETs in a  
half-bridge configuration with supply voltages up to  
100V. Both high-side and low-side drivers can drive the  
MOSFETs with a different ground reference, providing  
excellent noise and transient immunity.

Its powerful 0.8Ω pull-down and 1.5Ω pull-up MOSFET  
drivers allows the use of large gate capacitance high volt-  
age MOSFETs. Additional features include UVLO, Three-  
State PWM input, adjustable turn-on/-off delays and  
shoot-through protection.
