L4953G Datasheet PDF - STMicroelectronics

DESCRIPTION
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-byline to allow the µP to store data.

■ 3 OUTPUTS:
    9.2V (500mA);
    5V (1A);
    5V (100mA) STANDBY
■ OUT1 (9.2V) AND OUT2 (5V) WITH INDEPENDENT ENABLE CONTROL FOR STAND BY MODE
■ 2A HIGH SIDE DRIVER WITH CLAMPED OUTPUT (16V)
■ LOGIC OUTPUT FOR:
    – SUPPLY UNDERVOLTAGE (LVW)
    – OVERVOLTAGE
    – THERMAL PROTECTION
■ RESET FUNCTION
■ IGNITION COMPARATOR
■ REVERSE BATTERY AND LOAD DUMP PROTECTION
■ THERMAL SHUTDOWN
