DESCRIPTION
Dual High Voltage, High Side
Current Sense Amplier
The LTC
6103 is a versatile, high voltage, high side, dual
current sense amplier. The two internal ampliers are
independent except that they share the same V– terminal.
Design exibility is provided by the excellent device char-
acteristics: 450V maximum offset, and only 275A of
current consumption (typical at 12V) for each amplier.
The LTC6103 operates on supplies from 4V to 60V.
The LTC6103 monitors current via the voltage across an
external sense resistor (shunt resistor). Internal circuitry
converts input voltage to output current, allowing for a
small sense signal on a high common mode voltage to be
translated into a ground referenced signal. Low DC offset al-
lows the use of a small shunt resistor and large gain-setting
resistors. As a result, power loss in the shunt is minimal.
The wide operating supply range and high accuracy make
the LTC6103 ideal for an extensive variety of applications
from automotive to industrial and power management.
The fast response makes the LTC6103 the perfect choice
for load current warnings and shutoff protection control.
With very low supply current, the LTC6103 is suitable for
power sensitive applications.
The LTC6103 is available in an 8-lead MSOP package.
