UNIVERSAL SOURCE DRIVER
NJM3548
s GENERAL DESCRIPTION
s PACKAGE OUTLINE
NJM3548 is a bipolar universal high-current highly protected
high side driver with transparent input and 2000mA continuous
-current source capability. A low-level input activates the output.
The driver is equipped with extensive electrical protection,
such as over current protection and thermal protection, which
makes the device virtually indestructible.
Furthermore it can detect open circuit and short circuit to VCC.
A special feature is the Error indicating output function pin
which signals to the host system if the protection or the load
check functions is activated.
Typical loads are solenoids, relays or resistive loads.
The NJM3548 and NJM3545 are complementary drivers and
have similar data.
