Microcontroller-based power-management chip for rugged mission-critical applications introduced by Infineon
MUNICH – Infineon Technologies AG in Munich is introducing the TLF35585 power-management IC, an integrated multi-rail power supply for demanding automotive and other mission-critical systems.
The TLF35585 provides a power supply for AURIX and other microcontrollers and provides rugged systems with high functional safety requirements.
The new power supply is for safety applications in harsh automotive environments, particularly in the chassis, powertrain, domain control, and transmission.
The TLF35585 power-management IC includes a boost buck pre-regulator that supplies the post-regulator rails for the microcontroller supply, communication supply, and a precise voltage reference.
Time-based trigger
It also provides two trackers that follow the voltage reference to supply off-board sensors. Supervision includes a configurable time-based trigger window watchdog, a question-and-response-based trigger watchdog, error pin monitoring, and voltage monitoring.
For interaction with the microcontroller, a 16-bit SPI, interrupt and reset function are available. The device complies with ISO 26262 for systems to ASIL D and supports an extended junction temperatures to 175 degrees Celsius.
The IC integrates a state machine, the wake-up concept with timer and a stand-by regulator. The TLF35585 is available in a small VQFN-48 package or a TQFP-48 package. For more information contact Infineon online at www.infineon.com/optireg-pmic.
