Description

The ZXCT1080 is a high side current sense monitor with a gain of 10 and a voltage output. Using this device eliminates the need to disrupt the ground plane when sensing a load current. The wide input voltage range of 60V down to as low as 3V make it suitable for a range of applications; including systems operating from industrial 24-28V rails and -48V rails.

Feature(s)

  • 3V to 60V continuous high side voltage
  • Accurate high-side current sensing
  • -40 to 125°C temperature range
  • Output voltage scaling x10
  • 4.5V to 12V VCC range
  • Low quiescent current:
  • 80μA supply pin
  • 27μA IS+
  • SOT25 package
  • Application(s)

  • Industrial applications current measurement
  • Battery management
  • Over-current measurement
  • Power management
  • Automotive current measurement
  • Product Specifications
