ZXCT1081

Absolute maximum ratings

Continuous voltage on SENSE+ and SENSE-

-0.6V and 45V

Transient voltage on SENSE+ and SENSE-

-0.6V and 65V

Voltage on all other pins

-0.6V and 14V

Differential sense voltage, VSENSE

Operating temperature

800mV

-40°C to 125°C

Storage temperature

-55°C to 150°C

Maximum junction temperature

85°C

Package power dissipation

300mW at TA = 25°C (de-rate to zero at 125°C)

Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for

extended periods, may reduce device reliability.

Pin Name

Description

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 SENSE+ This is the positive input of the current monitor and has an input range from

40V (60V transient) down to 3V. The current through this pin varies with

differential sense voltage

5 SENSE- This is the negative input of the current monitor and has an input range

from 40V (60V transient) down to 3V
