The setpoints for the coil’s energising and hold cur- rent 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 en- ergising to hold mode after 50 ms provided that the set energising current has been reached. The changeover between energising and hold modes is suitable for typical relay drives which require a powerful initial energising current which can then be reduced after closing the air gap in a magnetic cir- cuit. The quadratic dependence on the current inten- sity means that cutting the current by half reduces the power dissipation by ca. 75%. Using PWM the output current is controlled to the values set at RACT and RHOLD. The internal fly- back diode maintains the current during the switch- ing pauses. The switching frequency of ca. 80 kHz is provided by the internal oscillator. The device is shutdown by a Low signal at input EN or the removal of the power supply; the current re- duction in the coil is supported by the changeover of the free-wheeling circuit. The Zener diode now ac- tive permits higher free-wheeling voltages and thus a quicker demagnetising of the coil. The status indicator LED is constantly ON when hold mode is functioning correctly and flashes with low voltage, excessive temperature or when the coil cur- rent in energise mode has not reached the setpoint. The driver output is shutdown with low voltage or ex- cessive temperature. Alternatively to using an LED output DIAG signals the correct operating by out- putting a high signal. The input signal at EN can be synchronised with the zero crossing at input SYNC. Thus by using an ex- ternal R/C network, the switching of the coil can be synchronised with the load current of e.g. the relay.
