ZXCT1041
Bidirectional precision high-side current monitor
Description
The ZXCT1041 is a bidirectional precision high-
side current sense monitor. The output voltage
is proportional to the differential input voltage.
Direction of current flow is indicated by the
Flag pin.
The ZXCT1041 provides a fixed gain of 10 for
applications     where     minimal     external
components are required.
Features
"   Bidirectional high side measurement
"   Output voltage scaling x10
"   2.7V to 20V high side voltage
"   35礎 quiescent current
"   1% typical accuracy
"   SOT23-5 package
Pin connections
The very low offset voltage enables a typical
accuracy of 2% for sense voltages of only
10mV, giving better tolerances for small sense
resistors necessary at higher currents.
The wide input voltage range of 20V down to
as low as 2.7V make it suitable for a range of
applications.
A minimum operating current of just 40A,
combined with a SOT23-5 package makes the
ZXCT1041 particularly suitable for portable
battery equipment.
Applications
"   Battery management
"   Over current monitor
"   Battery gas gauging
"   Motor control
