  • The L4953G contains a triple voltage regulator and a power switch.

    The IC includes a monitoring circuit to warn if a low voltage or no voltage condition is occuring.
    In stand-by output is active as long as possible even when in thermal shutdown or any other fault conditions.
    The STCAP pin allows the use of a reserve supply capacitor that will hold enough energy for the 5V Stand-by line to allow the μP to store data.

    Key Features

    • REVERSE BATTERY AND LOAD DUMP PROTECTION
    • IGNITION COMPARATOR
    • 3 OUTPUTS: 9.2V (500mA); 5V (1A); 5V (100mA) STANDBY\t
    • 2A HIGH SIDE DRIVER WITH CLAMPED OUTPUT (16V)
    • OUT1 (9.2V) AND OUT2 (5V) WITH INDEPENDENT ENABLE CONTROL FOR STANDBY MODE
    • RESET FUNCTION
    • THERMAL SHUTDOWN
    • LOGIC OUTPUT FOR:\t\tSUPPLY UNDERVOLTAGE (LVW)\t\tOVERVOLTAGE (FAULT)\t\tTHERMAL PROTECTION (FAULT)\t\t
