TLF35584QVVS2XUMA2

TLF35584QVVS2XUMA2 is a OPTIREG™, functional safety PMIC. 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 favours the usage in numerous applications. Multiple safety features enable easy realization of ASIL-D together with various Microcontrollers (µCs). Potential application includes electric power steering, battery management, inverter, transmission, engine management, domain control.
