HIGH-SIDE CURRENT MONITOR
ZXCT1009
DESCRIPTION
The ZXCT1009 is a high side current sense monitor.
Using this device eliminates the need to disrupt the
ground plane when sensing a load current.
APPLICATIONS
Battery chargers
Smart battery packs
It takes a high side voltage developed across a current DC motor control
shunt resistor and translates it into a proportional
output current.
Over current monitor
A user defined output resistor scales the output current
into a ground-referenced voltage.
The wide input voltage range of 20V down to as low as
2.5V make it suitable for a range of applications. A
minimum operating current of just 4A, combined with
its SOT23 package make it a unique solution for
portable battery equipment.
Power management
Level translating
Programmable current source
