FDMS2380 Dual Integrated Solenoid Driver August 2007 FDMS2380 Dual Integrated Solenoid Driver Features „ 5A, 60V Load Clamp „ rDS(ON) = 30mΩ (Typ.) Excitation path „ 6V to 26V Operation „ CMOS Compatible „ Soft Short Detection „ Thermal Shutdown „ Diagnostic Output „ Integrated Clamps „ Over-current Protection „ Open Load Detection „ Over-voltage Protection Pin 1 General Description The FDMS2380 is an intelligent low side driver with built in recirculation and demagnetization circuits designed specifically for driving inductive loads. The inputs are CMOS compatible. A separate diagnostic signal for each channel provides the system with an indication of the operation of the solenoid or the presence of a protection fault condition. Built-in Over-voltage, Over-current, Overtemperature circuits protect the device from these conditions. Additional diagnostic circuitry is included for detecting Open Load, Under-voltage and output ground fault conditions. The FDMS2380 contains two independent intelligent low side solenoid drivers.
