Power-Saving PWM Relay/Solenoid Driver

iC-JE is a PWM driver for inductive loads, such as relay coils, solenoid valves and small DC motors.

The setpoint for the coil current is preset with the external resistor, RSET. 60 to 300 mA can be set for energise mode which then automatically drop to 2/3 of this value (40 to 200 mA) during hold mode. The device is switched to hold mode after 100 ms provided that the set coil current is obtained during energising.
