ZXCT1080

Absolute maximum ratings

Continuous voltage on S- and S+

-0.6 and 65V

Voltage on all other pins

-0.6V and +14V

Differential sense voltage, VSENSE

Operating temperature

800mV

-40 to 125°C

Storage temperature

-55 to 150°C

Maximum junction temperature

125°C

Package power dissipation

300mW* at TA = 25°C

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

maximum ratings, for extended periods, may reduce device reliability.

VSENSE is defined as the differential voltage between S+ and S- pins.

* Assumes ⍜JA = 420°C/W

Description

This is the analogue supply and provides power to internal circuitry

Ground pin

Output voltage pin. NMOS source follower with 20µA bias to ground

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

60V down to 3V. The current through this pin varies with differential sense

voltage

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

from 60V down to 3V
