ZXCT1021
ZXCT1022
LOW OFFSET HIGH-SIDE CURRENT MONITOR
DESCRIPTION
The ZXCT1021/1022 are precision high side current
sense monitors. Using this type of device eliminates
the need to disrupt the ground plane when sensing a
load current.
The ZXCT1021 provides a fixed gain of 10 while the
ZXCT1022 has a gain of 100, for applications where
minimal sense voltage is required.
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
2.5V make it suitable for a range of applications. With a
minimum operating current of just 25µA, combined
with its SOT23-5 package make it suitable for portable
battery equipment too.
APPLICATIONS
Battery Chargers
Smart Battery Packs
DC Motor control
Over current monitor
Power Management
Level translating
Programmable current source
FEATURES
Accurate high-side current sensing
Output voltage scaling
2.5V – 20V supply range
