PRODUCTION DATA.
The key elements to identify here are the system input voltage, peak current, hold current, and peak keep time values required for the solenoid or relay being used. With these values, approximate RS, RPEAK, RHOLD (for 14-pin package), CKEEP, and RSENSE values can be determined and the proper FET and diode can be identified. ROSC can be varied in order to tune the circuit to the chosen solenoid or relay.
