ZXCT1009 HIGH-SIDE CURRENT MONITOR Pin Descriptions Pin Name Pin Function
VSENSE+ Connection to supply voltage VSENSE- Connection to load IOUT Output current, proportional to measured current
Absolute Maximum Ratings (TA = 25
°
C) Description Rating Unit
Voltage on any pin (relative to IOUT) -0.6 to 20 V Continous output current, IOUT 25 mA † Continuous sense voltage, VSENSE -0.5 to +5 V Operating temperature, TA -40 to 85 °C Storage temperature -55 to 125 °C Package power SOT23 450 mW dissipation @ TA = 25°C (Derate to zero @ 125°C) SM8 2 W Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings for extended periods may reduce device reliability.
