iC-JE
PWM RELAY/SOLENOID DRIVER
FEATURES
• Wide operating voltage range of 10 to 45 Vdc
• PWM control for coil currents of 40 to 300 mA
• Coil current for energise and hold modes set by an external
resistor
• Coil current monitored during energise mode, detection of load
breakage and voltage errors
• Automatic current reduction after 100 ms to reduce the power
consumption in hold mode
• The internal free-wheeling alteration function supports PWM
operation and quick demagnetising during shutdown
• Status signalled at the current-limited LED output
• Shutdown with excessive temperature and low voltage
• Integrated oscillator needs no external components
• PWM frequency is beyond audible range
• Protective circuitry against damage by ESD
• Minimum space requirements, few external components

APPLICATIONS
• PWM drive for inductive loads
(e.g. relays, electrovalves)
• Relay low-/high-side switch
