DESCRIPTION
High Voltage, High Side,
Bi-Directional Current
Sense Amplier
The LTC
6104 is a versatile, high voltage, high side, bi-
directional current sense amplier. Design exibility is
provided by the excellent device characteristics: ±450V
maximum offset and only 520A of current consumption
(typical at 12V). The LTC6104 operates on supplies from
4V to 60V.
The LTC6104 monitors bi-directional current via the voltage
across an external sense resistor (shunt resistor). This
sense voltage is then translated into a ground referenced
signal. Gain is set with three external resistors and can
be separately congured for both directions. Low DC
offset allows 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 LTC6104 ideal for a wide variety of automotive, industrial
and power management applications. A maximum input
sense voltage of 500mV allows a wide range of currents
to be monitored. The fast response makes the LTC6104
the perfect choice for load current warnings and shutoff
protection control. With very low supply current, the
LTC6104 is suitable for power sensitive applications.
The LTC6104 is available in an 8-lead MSOP package.
