Current Sensor
Issue 2 - July 2006
ZMC10D
•
Package : mod. DIL-14 (12 pin)
•
Double magnetic sensor chip (employing
the magnetoresistive effect of thin film per-
malloy) measures the magnetic field gen-
erated by an internal current-carrying
conductor
•
measurable direct or alternating current I
M
up to 10A
•
supply voltage 12 V
•
no auxiliary field H
X
required
•
it’s possible to overload the conductor (be-
tween pin’s 8,9,10 and 11,12,13) with
300A for 10 ms at T
amb
= 25 °C
