DESCRIPTION

The LTC®6101/LTC6101HV are versatile, high voltage, high
side current sense amplifi ers. Design fl exibility is provided
by the excellent device characteristics; 300V Max offset
and only 375A (typical at 60V) of current consumption.
The LTC6101 operates on supplies from 4V to 60V and
LTC6101HV operates on supplies from 5V to 100V.

The LTC6101 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 allows the use of a small shunt resistor and large
gain-setting resistors. As a result, power loss in the shunt
is reduced.

The wide operating supply range and high accuracy make
the LTC6101 ideal for a large array of applications from
automotive to industrial and power management. A maxi­mum input sense voltage of 500mV allows a wide range
of currents to be monitored. The fast response makes the
LTC6101 the perfect choice for load current warnings and
shutoff protection control. With very low supply current,
the LTC6101 is suitable for power sensitive applications.

The LTC6101 is available in 5-lead SOT-23 and 8-lead
MSOP packages.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.

Note 2: The LTC6101C/LTC6101HVC are guaranteed to meet specifi ed
performance from 0°C to 70°C. The LTC6101C/LTC6101HVC are designed,

characterized and expected to meet specifi ed performance from –40°C to
85°C but are not tested or QA sampled at these temperatures. LTC6101I/
