ZXCT1080Q/ ZXCT1081Q
AUTOMOTIVE GRADE 60/40V HIGH-SIDE CURRENT MONITOR
Description
The ZXCT1080Q and ZXCT1081Q are high side current sense
monitors with a voltage output and a fixed gain of 10. Using this
device eliminates the need to disrupt the ground plane when sensing
a load current.
The wide input voltage range of 60V and 40V, respectively, down to
as low as 3V make it suitable for a range of automotive applications
with 60V and 40V load dump withstand capabilities.
Pin Assignments
VCC 1
GND 2
OUT 3
5 S-
74 S+
The separate supply pin (VCC) allows the device to continue
functioning under short circuit conditions.
The ZXCT1080Q and ZXCT1081Q have an extended ambient
operating temperature range of -40°C to 125°C enabling it to be used
in a wide range of automotive applications including.
The ZXCT1080Q and ZXCT1081Q have been qualified to AEC-Q100
Grade 1 and are Automotive Grade supporting PPAPs.
