LTC6101ACMS8 High Voltage High-Side Current Sense Amplifier in SOT-23

The LTC6101/LTC6101HV are versatile, high voltage, high
side current sense amplifiers. Design flexibility is provided
by the excellent device characteristics; 300µV Max offset
and only 375µA (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 trans-
lated 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 maxi-
mum 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.
