Function
1
VCC This is the analogue supply and provides power to internal circuitry
2
GND Ground pin
3
OUT Output voltage pin. NMOS source follower with 20μA bias to ground
4
S+
This is the positive input of the current monitor.
The current through this pin varies with differential sense voltage
5
S- This is the negative input of the current monitor.

Caution:
Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at conditions between maximum recommended operating conditions and absolute maximum ratings is not implied.
Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling
and transporting these devices.
Notes: 5. ZXCT1080 has a maximum transient and continuous voltage of 65V on the S+ and S- pin. The ZXCT1081 has a maximum continuous of 45V, it
however can withstand transient up to 65V.
6. VSENSE is defined as the differential voltage between S+ and S- pins
7. Assumes θJA = 420°C/W
