Current Sense Ampliﬁer

DESCRIPTION

The LTC

®

6102/LTC6102HV are versatile, high voltage,

high-side current sense ampliﬁers. Their high supply

voltage rating allows their use in almost any application,

while the low drift and offset ensure accuracy across a

wide range of operating conditions.

The LTC6102/LTC6102HV monitor current via the voltage

across an external sense resistor (shunt resistor). Internal

circuitry converts input voltage to output current, allowing

a small sense signal on a large common mode voltage to

be translated to a ground-referred signal. Low DC offset

allows the use of very low shunt resistor values and large

gain-setting resistors. As a result, power loss in the shunt

is reduced.

The wide operating supply and high accuracy make the

LTC6102/LTC6102HV ideal for a large array of applications

from automotive to industrial and power management. A

maximum input sense voltage of 2V allows a wide range

of currents and voltages to be monitored. Fast response

makes the LTC6102/LTC6102HV the perfect choice for load

current warnings and shutoff protection control.

The LTC6102/LTC6102HV are available in 8-lead MSOP

and 3mm × 3mm DFN packages.

LTC6102/LTC6102HV

ELECTRICAL CHARACTERISTICS

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. In addition to the Absolute Maximum Ratings, the

output current of the LTC6102 must be limited to ensure that the power

dissipation in the LTC6102 does not allow the die temperature to exceed

150°C. See the Applications Information “Output Current Limitations Due

to Power Dissipation” for further information.

Note 2:

The LTC6102C/LTC6102HVC are guaranteed to meet speciﬁed

performance from 0°C to 70°C. The LTC6102C/LTC6102HVC are designed,

characterized and expected to meet speciﬁed performance from –40°C to

85°C but are not tested or QA sampled at these temperatures. LTC6102I/

LTC6102HVI are guaranteed to meet speciﬁed performance from –40°C

to 85°C. The LTC6102H/LTC6102HVH are guaranteed to meet speciﬁed

performance from –40°C to 125°C.

Note 3:

These Parameters are guaranteed by design and are not 100%

tested. Thermocouple effects preclude measurements of these voltage

levels during automated testing.

Note 4:

Limits are fully tested. Limit is determined by high speed

automated test capability.

Note 5:

I

B

speciﬁcation is limited by practical automated test resolution.

Please refer to the Typical Performance Characteristics section for

more information regarding actual typical performance. For tighter

speciﬁcations, please contact LTC Marketing.
