PWM RELAY/SOLENOID DRIVER
EVALUATION BOARD
Rev F1, Page 8/9
The iC-JE is equipped with a Evaluation Board for test
purposes. The following figures show the circuit dia-
gram as well as the top and bottom layout of the test
PCB.
The board comes with a strap between IN and
SENSE1 (application equal to Fig. 4). The actual coil
current can be measured by the voltage drop between
SENSE1 and SENSE2 (1 mV/mA).
