ar y n i im prel iC-GE100 PWM RELAY/SOLENOID DRIVER Rev B1, Page 2/12 DESCRIPTION iC-GE100 is a PWM driver for inductive loads, such as relay coils, solenoid valves and other inductive loads. The setpoints for the coil’s energising and hold current are pre-set by means of external resistors RACT and RHOLD. These currents can be set in a range from 10 to 100 mA. The iC-GE100 switches from energising to hold mode after 50 ms provided that the set energising current has been reached.
