MPQ70332FSGQKTE-xxxxAEC-Z

The MPQ70332FS-AEC1 is an ASIL-B compliant power management IC (PMIC) with advanced safety features for automotive applications. It consists of a high-voltage (HV) primary synchronous buck converter, a low-voltage (LV) secondary synchronous buck converter, and a synchronous boost converter with excellent transient response. Voltage monitoring is implemented via a voltage supervisor to monitor the battery input voltage (VIN), output rails, and two external channels, along with critical internal voltage signals, including the VCC voltage (VCC) and bandgap reference. Clock monitoring, leakage monitoring, and thermal monitoring are also implemented. Built-in self-testing (BIST) is included for critical analog and logic functions. A failsafe state machine manages fault handling and controls the safety outputs. The integrated, configurable watchdog timer can be configured in window and Q&A modes. The safety-related blocks include independent voltage regulators, bandgaps, and oscillators, providing redundancy to ensure failsafe operation. The serial peripheral interface (SPI) allows for flexibility through configurability. The one-time programmable (OTP) memory allows settings to be permanently stored. SPI transactions, data in the registers, and the OTP memory are protected via cyclic redundancy check (CRC). The MPQ70332FS-AEC1 is available in a TQFN-34 (6mmx6mm) package, and is available in AEC-Q100 Grade 1.
