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 and has an input range from

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

voltage

5

S-

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

from 60V down to 3V
