The LMP8646 is a precision current limiter used to improve the current limit accuracy of
any switching or linear regulator with an available feedback node.
The LMP8646 accepts input signals with a common-mode voltage ranging from –2 V to 76 V.
It has a variable gain which is used to adjust the sense current. The gain is configured with a
single external resistor, RG, providing a high level of flexibility and
accuracy up to 2%. The adjustable bandwidth, which allows the device to be used with a variety of
applications, is configurable with a single external capacitor in parallel with
RG. In addition, the output is buffered in order to provide a low output
The LMP8646 is an ideal choice for industrial, automotive, telecommunications, and
consumer applications where circuit protection and improved precision systems are required. The
LMP8646 is available in a 6-pin SOT package and can operate at temperature range of −40°C to
