The Si5SSD2-FBR-50V-2x16A is a “Smart” Dual, 50V 2x16A Solenoid Driver with Fixed Load-Current Boost/Reduction and with integrated finned heat sink. The words "Fixed Boost/Reduction" implies that after a coil is prompted, 100% PWM Load-Current is used with that coil for 100msec (Boost) and after this time, the PWM is reduced to 50% (the Time Duration and Reduction Factor is Fixed). The initial current boost is required to increase the pull-in force of the solenoid coil with an iron plunger, while the current reduction prevents overheating. An onboard microprocessor generates a 5kHz or 20kHz PWM carrier signal, controls the boost-time/reduction-factor, and monitors the control inputs (at 2kHz sampling rate). The PWM carrier frequency is user selectable by the jumper CN3, 20kHz when CN3 is open and 5kHz when short.
