SNIS191A – JULY 2015 – REVISED JULY 2015 LM57-Q1 Resistor-Programmable Temperature Switch and Analog Temperature Sensor
1 Features 3 Description The LM57-Q1 device is a precision, dual-output,
temperature switch with analog temperature sensor
output for wide temperature applications such as
automotive grade. The trip temperature (TTRIP) is
selected from 256 possible values in the range of
–40°C to 160°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 Qualified for Automotive Applications, for
