6101 TA01

DESCRIPTION

The LTC

side current sense ampliﬁ ers. Design ﬂ exibility 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 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 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.
