... Description The ZXCT1041 is a bidirectional precision high- side current sense monitor. The output voltage is proportional to the differential input voltage. Direction of current flow is indicated by the Flag pin. The ZXCT1041 provides a fixed gain of 10 for applications where minimal components are required. Features • ...

... The direction of measured current flow is determined by comparing the voltages applied to the bases of transconductance transistors (Q1 and Q2). For maximum versatility the flag output uses an open collector; this allows the ZXCT1041 to monitor rails at a much higher potential than what the flag output is interfacing to. ...
