L99SD01-E

INDUCTIVE LOAD DRIVER, 14A, POWERSSO-36.

The L99SD01-E is an Integrated Solenoid Driver intended for driving inductive loads such as compressed natural gas (CNG) injectors. The inputs are CMOS-compatible. The diagnostic outputs CLAMP_FLAG and FAULT provide an indication of demagnetization mode and fault conditions, respectively. The integrated standard serial interface (I?C) allows to digitally set peak and holds current values and other injection parameters. It also provides detailed diagnostic information. The device should work with pre-programmed peak and hold current values when values are not set by external micro. All injection parameters can be changed during operating conditions and taken into account at the first injection rising edge after the end of communication. Diagnostic information is available in case of overcurrent, over-temperature, over-voltage and open-load.
