Output voltage pin. NMOS source follower with 20

μA 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
