LT6108-1/LT6108-2

High Side Current Sense

Ampliﬁer with Reference

and Comparator

FEATURES

DESCRIPTION

The LT^®6108 is a complete high side current sense device

that incorporates a precision current sense ampliﬁer, an

integrated voltage reference and a comparator. Two ver-

sions of the LT6108 are available. The LT6108-1 has a

latching comparator and the LT6108-2 has a non-latching

comparator. In addition, the current sense ampliﬁer and

comparatorinputsandoutputsaredirectlyaccessible.The

ampliﬁer gain and comparator trip point are conﬁgured

by external resistors. The open-drain comparator output

allows for easy interface to other system components.

Current Sense Ampliﬁer

– Fast Step Response: 500ns

– Low Offset Voltage: 125µV Maximum

– Low Gain Error: 0.2% Maximum

Internal 400mV Precision Reference

Internal Comparator

– Fast Response Time: 500ns

– Total Threshold Error: 1.25% Maximum

– Latching or Non-Latching Comparator Option

Wide Supply Range: 2.7V to 60V

Supply Current: 450µA

Low Shutdown Current: 5µA Maximum

TheoverallpropagationdelayoftheLT6108istypicallyonly

1.4µs, allowing for quick reaction to overcurrent condi-

tions. The 1MHz bandwidth allows the LT6108 to be used

for error detection in critical applications such as motor

control. The high threshold accuracy of the comparator,

combined with the ability to latch the comparator, ensures

the LT6108 can capture high speed events.

Speciﬁed for –40°C to 125°C Temperature Range

Available in 8-Lead MSOP and 8-Lead (2mm × 3mm)

DFN Packages

APPLICATIONS

Overcurrent and Fault Detection

The LT6108 is fully speciﬁed for operation from –40°C to

125°C, making it suitable for industrial and automotive

applications. The LT6108 is available in the small 8-lead

MSOP and 8-lead DFN packages.
