Description

The ZXCT1050E5-7-90 is a current monitor integrated circuit chip that is applicable in a wide input range. It can operate on a range of input voltages from ground up to VCC-2V and can be used on the high or low side of the load. This chip offers variable gain with the use of two external resistors, where one resistor sets the transconductance and the other sets the overall gain. The low offset voltage of the ZXCT1050 enables a typical accuracy of 1% for sense voltages of only 30mV, making it ideal for use with small sense resistors necessary for higher currents.
