... ZXCT1081 High voltage high-side current monitor Description The ZXCT1081 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 40V down to as low as 3V make it suitable for a range of applications ...

... SENSE SENSE+ SENSE- (b) The ZXCT1081 operates from a positive power rail and the internal voltage-current converter current flow is unidirectional; these result in the output offset voltage for V (c) For V > 10mV, the internal voltage-current converter is fully linear. This enables a true offset to be defined and SENSE used ...

... Application information The ZXCT1081 has been designed to allow it to operate with 5V supply rails while sensing common mode signals up to 40V. This makes it well suited to a wide range of industrial and power supply monitoring applications that require the interface to 5V systems while sensing much higher voltages ...
