Description
- The TPS653853-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 microcontrollers with dual-core lockstep (LS) or loosely coupled architectures (LC).
- The TPS653853-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. An integrated charge pump provides an overdrive voltage for the internal regulators, and can also be used to drive an external NMOS FET as reverse battery protection. The device supports wake-up from an ignition (IGN) signal or wake-up from a CAN transceiver signal.
- The device has a steering-angle monitoring (SAM) unit that allows the ECU to indirectly capture the position of the steering wheel through the motor-position sensors. A dedicated low-power mode allows this SAM unit to operate even when the ECU is in sleep mode. Integrated SAM-switches allow passing-through of the Motor-Position Sensor signals to the MCU during normal operation, or decoupling the MCU ADC inputs from the motor-position sensor signals when the ECU is in sleep mode.
- An independent voltage monitoring unit inside the device monitors undervoltage and overvoltage on all internal supply rails and regulator outputs of the battery supply. Regulator current limits and temperature protections are also implemented. The TPS653853-Q1 device features a question-answer watchdog, MCU error-signal monitor, clock monitoring on internal oscillator, self-check on clock monitor, cyclic redundancy check (CRC) on non-volatile memory and SPI communication, a diagnostic output pin allowing MCU to observe device internal analog and digital signals, a reset circuit for the MCU and an enable output to disable external power-stages on any detected system-failure. A built-in self-test (BIST) allows for monitoring the device functionality at start-up. A dedicated DIAGNOSTIC state allows the MCU to check TPS653853-Q1 functionality.
- The TPS653853-Q1 device also has an error reporting capability through the SPI register. The device has separate status bits in the SPI register for each specific error on the system level or device level. When the device detects a particular error condition, it sets the appropriate status bit and keeps this status bit set until the MCU reads-out the SPI register in which this status bit was set. Based on which status bit was set, the MCU can decide whether it must keep the system in a safe state or whether it can resume with the operation of the system.
- The TPS653853-Q1 device is available in a 48-pin HTSSOP PowerPAD IC package.
