ZXCT1011 - High-side low drift current monitor

General Description

The ZXCT1011 is a high side current sense monitor.

Using this type of device eliminates the need to disrupt the ground plane when sensing a load current.

The ZXCT1011 takes the voltage developed across a current shunt resistor and translates it into a proportional output current.

Key Features

  • Accurate high-side current sensing.
  • 2.5V to 20V supply range.
  • 4 µA quiescent current.
  • 1% typical accuracy.
  • Package SOT23-5.
  • Temperature range -40 to 125°C.

ZXCT1011 High-side low drift current monitor Description The ZXCT1011 is a high side current sense monitor. Using this type of device eliminates the need to disrupt the ground plane when sensing a load current. The ZXCT1011 takes the 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. A current reference resistor, external to the IC, results in an improved temperature coefficient compared to the ZXCT1009. 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 4uA, combined with its SOT23-5 package make it suitable for portable battery equipment too.
