ZXCT1009 - HIGH-SIDE CURRENT MONITOR

General 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.

It takes a high side voltage developed across a current shunt resistor and translates it into a proportional output current.

Key Features

  • Low cost, accurate high-side current sensing.
  • Output voltage scaling.
  • Up to 2.5V sense voltage.
  • 2.5V to 20V supply range.
  • 4μA quiescent current.
  • 1% typical accuracy.
  • SOT23 and SM8 packages.
  • AEC-Q100.3 qualified; ZXCT1009FTA only Pin Assignments SOT23 Package Suffix.

ZXCT1009 HIGH-SIDE CURRENT MONITOR 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. It takes a high side voltage developed across a current shunt resistor and translates it into a proportional output current. 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 4µA, combined with a SOT23 package make it a unique solution for portable battery equipment. The SM8 device offers an alternative package option. Features • Low cost, accurate high-side current sensing • Output voltage scaling • Up to 2.
