Power Management Specialised - PMIC SafeTI-ISO26262 ASIL-D multi-rail power supply for MCUs with 500mA I/O rail and rotation counter 48-HTSSOP -40 to 125

Description:

The TPS653853A-Q1 and TPS653854A-Q1 device is a multirail power supply designed to supply microcontrollers in safety relevant applications, such as those found in the automotive industry. The device supports functional safety microcontrollers with dual-core lockstep (LS) and other multi-core architectures.

The TPS653853A-Q1 and TPS653854A-Q1 device integrates multiple supply rails to power the MCU, CAN or FlexRay, and external sensors. A buck-boost converter with internal FETs converts the input battery voltage between 2.3 V and 36 V to a 6-V preregulator output that supplies the other regulators.

Applications

• Automotive Safety-Relevant Applications
• Industrial Safety-Relevant Applications
