Overview

February 1999 PBD 3548/1 Universal Source Driver Description PBD 3548/1 is a bipolar universal high-current highly-protected high side driver with transparent input and 2 A continuous-current source capability.
A low-level input activates the output.
The driver is equipped with extensive electrical protection, such as overcurrent protection and thermal protection, which makes the device viritually 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 PBD 3548/1 and PBD 3545/1 are complementary drivers and have similar data.
