TLF35584QVVS1XUMA2

TLF35584QVVS1XUMA2 is a multi voltage safety micro processor supply in a 48 pin VQFN package. This multiple output system supply for safety-relevant applications supplying 5V-μC, transceivers, and sensors by an efficient and flexible pre-/post-regulator concept over a wide input voltage range. The wide switching frequency range allows optimization in respect of efficiency and usage of small filter components. A dedicated reference-regulator supplies the ADC independent from μC-load steps and acts as tracking-source for the 2 independent sensor-supplies. The flexible state machine, wake-up concept including timer, and the stand-by-regulator favors the usage in numerous applications. Multiple safety features enable easy realization of ASIL-D together with various Microcontrollers. The TLF355854 is featured as power supply and safety monitor on the Hitex ShieldBuddy AURIX™ TC375.
