DESCRIPTION
Precision Zero Drift
Current Sense Amplifi er
The LTC
®
6102/LTC6102HV are versatile, high voltage,
high-side current sense amplifi ers. Their high supply
voltage rating allows their use in almost any application,
while the low drift and offset ensure accuracy across a
wide range of operating conditions.
The LTC6102/LTC6102HV monitor current via the voltage
across an external sense resistor (shunt resistor). Internal
circuitry converts input voltage to output current, allowing
a small sense signal on a large common mode voltage to
be translated to a ground-referred signal. Low DC offset
allows the use of very low shunt resistor values and large
gain-setting resistors. As a result, power loss in the shunt
is reduced.
The wide operating supply and high accuracy make the
LTC6102/LTC6102HV ideal for a large array of applications
from automotive to industrial and power management. A
maximum input sense voltage of 2V allows a wide range
of currents and voltages to be monitored. Fast response
makes the LTC6102/LTC6102HV the perfect choice for load
current warnings and shutoff protection control.
The LTC6102/LTC6102HV are available in 8-lead MSOP
and 3mm × 3mm DFN packages.
