PBD 3545/1
Universal Sink Driver
Description
Key Features
PBD 3545/1 is a bipolar universal high-current highly-protected low side driver with
•
transparent input and 2 A continuous-current sink capability. A high-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 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.
Typical loads are solenoids, relays or resistive loads.
•
The PBD 3545/1 and PBD 3548/1 are complementary drivers and have similar data. •
