AUTOMOTIVE HIGH-SIDE CURRENT MONITOR
ZXCT1008
DESCRIPTION
The ZXCT1008 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.
APPLICATIONS
• Automotive current measurement
• DC motor and solenoid control
• Over current monitor
• Power management
The wide input voltage range of 20V down to as low as
2.5V make it suitable for a range of applications. The
ability to withstand high voltage transients and
reverse polarity connection, makes this part very
suitable for automotive and other transient rich
environments.
FEATURES
• Low cost, accurate high-side current sensing
• -40 to +125°C temperature range
• Up to 500mV sense voltage
• 2.5V – 20V supply range
• 4µA quiescent current
• 1% typical accuracy
• SOT23
