NJM3545
s GENERAL DESCRIPTION
s PACKAGE OUTLINE
NJM3545 is a bipolar universal high-current highly protected
low side driver with transparent input and 2000mA continuous
-current sink capability. A high-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 ground.
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.
The NJM3545 and NJM3548 are complementary drivers and
have similar data.
