PWM RELAY/SOLENOID DRIVER
preliminary
Rev A0.6, Page 1/11
FEATURES
o Current control for inductive actuators at 24 V (10 to 36 V)
o High efficient current control up to 1 A
o Power saving and power dissipation reduced switching
o Individual setting of energising and hold current
o Monitoring of coil current, supply voltage and temperature
o Status indication via LED or logic output
o Contact conserving switching of relays synchronous to the
mains
o Shutdown with overtemperature and undervoltage
o Fast demagnetising due to 15 V countervoltage
o High PWM frequency mit frequency spreading for low EMI
o Energising time of 50 ms prolongable with external capacitor
APPLICATIONS
o PWM drive for inductive loads
(e.g. 6/12 V relays,
electrovalves) from 24 V
o Relay low-/high-side switch
