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.

Features

  • Low cost, accurate high-side current sensing. Output voltage scaling. Up to 2.5V sense voltage. 2.5V.
  • 20V supply range. 4µA quiescent current. 1% typical accuracy. SOT23 & SM8† packages.

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 its SOT23 package make it a unique solution, suitable for portable battery equipment. FEATURES • • • • • • • Low cost, accurate high-side current sensing. Output voltage scaling. Up to 2.5V sense voltage. 2.5V – 20V supply range.
