Product Description
A synchronous boost-buck pre-regulator supporting a wide input voltage range of 3.0 V to 40 V, with full performance operation and low overall power consumption
Low-dropout post-regulator 5.0 V/200 mA, for communication power supply (QCO)
Low-dropout post-regulator 5.0 V/600 mA or 3.3 V/600 mA, for microcontroller power supply (QUC)
Voltage reference 5.0 V ±1%, for ADC power supply, output capability 150 mA (QVR)
Two trackers for sensor power supply, following the voltage reference, each with an output capability of 150 mA (QT1 and QT2)
Standby regulator 5.0 V/10 mA or 3.3 V/10 mA (QST)
Provides enable signal, synchronous output signal, and supports voltage monitoring with an optional external post-regulator (for core power supply)
Independent voltage monitoring module and error pin monitoring
Configurable window watchdog and functional watchdog
Safety state control, with two programmable delay safety state signals
16-bit SPI interface, supporting interrupt and reset functions
