LT6118

Current Sense Ampliﬁer,

Reference and Comparator

with POR

FeaTures

DescripTion

The LT^®6118 is a complete high side current sense device

that incorporates a precision current sense ampliﬁer, an

integrated voltage reference and a latching comparator.

The comparator latch functionality can be enabled or

disabled and the comparator can be conﬁgured to reset

upon power-on. The input and the open-drain output of

the comparator are independent from the current sense

ampliﬁer. The comparator trip point and ampliﬁer gain are

conﬁgured with external resistors.

Current Sense Ampliﬁer

– Fast Step Response: 500ns

– Low Offset Voltage: 200µV Maximum

– Low Gain Error: 0.2% Maximum

Internal 400mV Precision Reference

Internal Comparator

– Power-On Reset Capability

– Fast Response Time: 500ns

– Total Threshold Error: 1.25% Maximum

Wide Supply Range: 2.7V to 60V

Supply Current: 450µA

1.4µs, allowing for quick reaction to overcurrent condi-

tions. The 1MHz bandwidth allows the LT6118 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 LT6118 can capture high speed events.

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

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

Overcurrent and Fault Detection

The LT6118 is fully speciﬁed for operation from –40°C to

125°C, making it suitable for industrial and automotive

applications. The LT6118 is available in the small 8-lead

MSOP and 8-lead DFN packages.
