Electric power offer designed to produce microcontrollers in safety-relevant apps

Texas Instruments TPS653853A-Q1/TPS653854A-Q1 Multi-Rail Electrical power Source is intended to supply microcontrollers in safety-relevant purposes, such as all those witnessed while in the automotive marketplace. The product supports practical protection microcontrollers with dual-core lockstep along with other multi-core architectures. The products integrate many provide rails to electric power the MCU, CAN or FlexRay, and exterior sensors. A buck-boost converter, with interior FETs, converts the input battery voltage between two.3V and 36V to the 6V pre-regulator output that supplies the other regulators. An integrated demand pump offers an overdrive voltage with the inside regulators and may also be used to travel an exterior NMOS FET as reverse battery defense. The unit supports wake-up from an IGN pin or wake-up from a CAN transceiver or other sign.

The device provides a steering-angle monitoring (SAM) device that enables the Eu to indirectly seize the position from the steering wheel by the motor-position sensors. A committed low-power manner permits this SAM unit to operate regardless if the Ecu is in sleep manner. Integrated SAM-switches permit passing-through with the Motor-Position Sensor signals to your MCU all through ordinary procedure or decoupling the MCU ADC inputs from your motor-position sensor alerts in the event the Ecu is in sleep method.

An unbiased voltage checking unit within the product displays undervoltage and overvoltage on all inner provide rails and regulator outputs from the battery offer. Regulator latest limitations and temperature protections also are applied. The devices aspect a question-answer watchdog, MCU error-signal observe, clock monitoring within the inside oscillator, self-check on clock keep track of, CRC on non-volatile memory and SPI conversation. In addition, it contains a diagnostic output pin enabling MCU to watch product internal analog and digital signals, a reset circuit for the MCU (NRES pin), as well as a basic safety output (ENDRV pin) to disable exterior power-stages on any detected system-failure. The unit automatically runs a BIST at startup, along with the MCU might re-run the BIST for the duration of method run time by software manage if needed. A devoted DIAGNOSTIC state allows the MCU to examine system operation.

The units even have an error reporting capability by way of the SPI sign-up. The product has different position bits from the SPI register for each specific error on the process degree or gadget amount. Once the product identifies a selected error situation, it sets the suitable status bit and retains this standing bit established right up until the MCU reads-out the SPI sign-up through which this status little bit was established. Primarily based on which status little bit was established, the MCU can identify whether or not it have to hold the program within a safe and sound point out or whether it might continue on the operation with the program. The devices are AEC-Q100 skilled for automotive apps.
