TPS3700-Q1
SLVSCI7A –MARCH 2014–REVISED APRIL 2014
TPS3700-Q1 Window Comparator for Over- and Undervoltage Detection
1 Features 3 Description
The TPS3700-Q1 wide-supply voltage window

• Qualified for Automotive Applications
comparator operates over a 1.8-V to 18-V range. The
• AEC-Q100 Qualified With the Following Results:
device has two high-accuracy comparators with an
– Device Temperature Grade 1: –40°C to 125°C
internal 400-mV reference and two open-drain
