A Product Line ofDiodes IncorporatedZXCT1010ENHANCED HIGH-SIDE CURRENT MONITORDescriptionPin Assignments The ZXCT1010 is a high side current sense monitor. Using this SOT25 device eliminates the need to disrupt the ground plane when sensing Package Suffix - E5 a load current. It is an enhanced version of the ZXCT1009 offering reduced typical NC 1 5 V - SENSE output offset and improved accuracy at low sense voltage. GND 2 The wide input voltage range of 20V down to as low as 2.5V make it suitable for a range of applications. A minimum operating current of IOUT 3 4 V + SENSE just 4µA, combined with its SOT25 package make suitable for portable battery equipment.
