High Side Current Sense  
Amplifier with Reference  
and Comparators  
FEATURES  
DESCRIPTION  
The LT®6109 is a complete high side current sense device  
that incorporates a precision current sense amplifier, an  
integrated voltage reference and two comparators. Two  
versions of the LT6109 are available. The LT6109-1 has  
the comparators connected in opposing polarity and the  
LT6109-2hasthecomparatorsconnectedinthesamepolar-  
ity.Inaddition,thecurrentsenseamplifierandcomparator  
inputs and outputs are directly accessible. The amplifier  
gainandcomparatortrippointsareconfiguredbyexternal  
resistors. The open-drain comparator outputs allows for  
easy interface to other system components.

The overall propagation delay of the LT6109 is typically  
only 1.4µs, allowing for quick reaction to overcurrent  
and undercurrent conditions. The 1MHz bandwidth al-  
lows the LT6109 to be used for error detection in critical  
applications such as motor control. The high threshold  
accuracy of the comparators, combined with the ability to  
latch both comparators, ensures the LT6109 can capture  
high speed events.
