TLF35585QUS01
The TLF35585QUS01 PMIC is a multiple output Power Management IC for safety-relevant applications supplying 5V microcontroller, 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 microcontroller load steps and acts as tracking-source for the two-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 (μCs). The OPTIREGTM TLF35585QUS01 PMIC comes in TQFP – 48 packages capable for automated optical inspection. The package is thermally enhanced, fully AEC – Q100 Grade 0 qualified and capable to go beyond Grade 0.
The OPTIREGTM PMIC TLF35585 is a robust, safe and reliable supply companion for AURIXTM microcontrollers for a dependable system and enables the highest safety standard at system level when combined with AURIXTM microcontrollers TC2xx and TC3xx.
