ZXCT1080
High voltage high-side current monitor
Description
The ZXCT1080 is a high side current sense
monitor with a gain of 10 and a voltage
output. Using this device eliminates the need
to disrupt the ground plane when sensing a
load current.
The wide input voltage range of 60V down to
as low as 3V make it suitable for a range of
applications; including systems operating
from industrial 24-28V rails and -48V rails.
The separate supply pin (V
CC
) allows the device
to continue functioning under short circuit
conditions, giving an end stop voltage at the
output.
The ZXCT1080 has an extended ambient
operating temperature range of -40°C to 125°C
enabling it to be used in a wide range of
applications including automotive.
