MT9523CT-30BF5

Magn Tek · Current Sensors · SOP-8

MT9523CT-30BF5 from Magn Tek, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	IP+	passive	Positive terminal of the input current path (pins 1 and 2 tied), part of the ~1.0 mΩ typical conductor that is isolated at 2.5 kVrms 1 min from signal pins 5-8.
2	IP+	passive	Positive terminal of the input current path (pins 1 and 2 tied), part of the ~1.0 mΩ typical conductor that is isolated at 2.5 kVrms 1 min from signal pins 5-8.
3	IP-	passive	Negative terminal of the input current path (pins 3 and 4 tied); current flowing from IP+ to IP- gives a positive output slope above VOQ.
4	IP-	passive	Negative terminal of the input current path (pins 3 and 4 tied); current flowing from IP+ to IP- gives a positive output slope above VOQ.
5	GND	power_in	Signal ground.
6	VZCR	output	Zero-current reference voltage output, fixed at 2.5V for VCC=4.5~5.5V in this fixed-output (BF5) version, independent of supply.
7	VOUT	output	Analog voltage output proportional to the input current; zero-current output VOQ is 2.5V for this bidirectional fixed-output 5V version.
8	VCC	power_in	Supply voltage input; 5V supply version (VCC=4.5~5.5V for fixed output mode).
