ZXCT1030 - High-side current monitor with comparator

Product description The ZXCT1030 is a high side current sense monitor containing an internal reference and comparator with a non-latching output. Using this device eliminates the need to disrupt the ground plane when sensing a load current. The wide input voltage range of 20V down to as low as 2.2V make it suitable for a range of applications. Dynamics and supply current are optimised for the processing of fast pulses, associated with switch mode applications.
