Current monitor covers a wide range
With a typical temperature coefficient below 100ppm/C, the ZXCT1011 current monitor assures accurate measurement of DC currents over the temperature range -40 to +125C.
With a typical temperature coefficient below 100ppm/C, the ZXCT1011 current monitor from Zetex Semiconductors assures accurate measurement of DC currents over the temperature range -40 to +125C Designed to sense current on the high side, the IC avoids any disruption of the ground plane, often a cause of offset and the loss of true ground reference

Power devices qualify for automotive duties
Monitors, regulators and references meet the requirements of AEC-Q100 Grade 1 for operation in automotive environments at temperatures up to 125C.
Simple to use and needing few external components, the 5-pinned ZXCT1011 measures the voltage across a low value sense resistor and converts it into a proportional output current via an external shunt resistor.
The current is scaled by an output resistor to produce a 1% accurate ground referenced output voltage.
A maximum sense voltage of 500mV and a bandwidth of 1.5MHz mean the current monitor provides accurate monitoring of supply or load current in real time, and over a wide range of load currents, from microamps to hundreds of amps.
Coupled with its wide input voltage range of 2.5 to 20V and ability to withstand circuit transients, the ZXCT1011 will meet the requirements of a diverse range of demanding applications in automotive, telecomms and industrial control sectors.
The ZXCT1011's miniature SOT23-5 package and typical operating current of 4uA also makes it a good choice for portable battery operated equipment designs.
The ZXCT1011 is available from Zetex distributors for $0.58 in 1000 piece quantities.
