Current Sense Amplifier,
Reference and Comparators
with POR
Description Features Current Sense Amplifier – Fast Step Response: 500ns – Low Offset Voltage: 200µV Maximum – Low Gain Error: 0.2% Maximum
n Internal 400mV Precision Reference
n Internal Latching Comparators
– Power-On Reset Capability – Fast Response Time: 500ns – Total Threshold Error: ±1.25% Maximum – Two Comparator Polarity Options
n Wide Supply Range: 2.7V to 60V
n Supply Current: 550µA
n Specified for –40°C to 125°C Temperature Range
n Available in 10-Lead MSOP Package The LT®6119 is a complete high side current sense device
that incorporates a precision current sense amplifier, an
integrated voltage reference and two latching comparators.
Two versions of the LT6119 are available. The LT6119-1
has the comparators connected in opposing polarity and
the LT6119-2 has the comparators connected in the same
polarity. The comparator latch functionality can be enabled
or disabled and the comparators can be configured to reset
upon power-on. The input and the open-drain outputs of
the comparators are independent from the current sense
amplifier. The comparator trip points and amplifier gain
are configured with external resistors. n The overall propagation delay of the LT6119 is typically …
