ZXCT1081
High voltage high-side current monitor
Description
The ZXCT1081 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 40V down to
as low as 3V make it suitable for a range of
applications; including systems operating
from industrial 24-28V rails and power
supplies.
Features
• 3V to 40V continuous high side voltage
• Accurate high-side current sensing
• Output voltage scaling x10
• 4.5V to 12V VCC range
• Low quiescent current:
• 80µA supply pin
• 30µA ISENSE+
• SOT23-5 package
• -40°C to 125°C ambient temperature range
Pin connections
The separate supply pin (VCC) allows the device
to continue functioning under short circuit
conditions, giving an end stop voltage at the
output.
For automotive applications the ZXCT1081 has
a 60V transient capability and ambient
temperature range of -40°C to 125°C.
Applications
• Automotive current measurement
• Industrial applications current measurement
• Battery management
• Over current monitor
• Power management
• Power adapters
