L4947R
DESCRIPTION
The L4947/L4947R is a monolithic integrated circuit in Pentawatt package specially designed to provide a stabilized supply voltage for automotive and industrial electronic systems. Thanks to its very low voltage drop, in automotive applications the L4947/L4947R can work correctly even during the cranking phase, when the battery voltage BLOCK DIAGRAM
Pentawatt ORDERING NUMBERS: L4947 L4947R could fall as low as 6V. Furthermore, it incorporates a plete range of protection circuits against the dangerous overvoltages always present on the battery rail of the car. The reset function makes the device particularly suited to supply microprocessor based systems : a signal is available (after an externally programmable delay) to reset the microprocessor at power-on phase ; at power-off, this signal bees low inhibiting the microprocessor.
