LTC6102-1/LTC6102HV
Precision Zero Drift
Current Sense Amplifier
Description
The LTC®6102/LTC6102HV are versatile, high voltage, high-
side current sense amplifiers. Their high supply voltage
rating allows their use in many high side applications,
while the low drift and offset ensure accuracy across a
wide range of operating conditions. The LTC6102-1 is a
version of the LTC6102 that includes a low power disable
mode to conserve system standby power.
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 ideal for a large array of applications, from auto-
motive, 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 the perfect choice for load current warnings and
shutoff protection control.
All versions of the LTC6102 are available in 8-lead MSOP
and 3mm × 3mm DFN packages.
