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 plementary drivers and have similar data.
