SNIS152E – MAY 2009 – REVISED JULY 2015 LM57 Resistor-Programmable Temperature Switch and Analog Temperature Sensor
1 Features 3 Description The LM57 device is a precision, dual-output,
temperature switch with analog temperature sensor
output for wide temperature industrial applications.
The trip temperature (TTRIP) is selected from 256
possible values in the range of –40°C to 150°C. The
VTEMP is a class AB analog voltage output that is
proportional to temperature with a programmable
negative temperature coefficient (NTC). Two external
1% resistors set the TTRIP and VTEMP slope. The
digital and analog outputs enable protection and
monitoring of system thermal events. 1 See LM57-Q1 Data Sheet for AEC-Q100 Grade
1/Grade 0/Grade 0 Extended (Qualified and
Manufactured on an Automotive Grade Flow)
Trip Temperature Set by External Resistors with
Accuracy of В±1.7В°C or В±2.3В°C from -40В°C to
+150В°C …
