SMARTMOS ANALOG CONTROL IC
INTERNAL REGULATORS & SAFETY:
VOLTAGE REGULATION
voltage for the Analog IC, as well as the VDD/VSS rails for
the core IC. The on-chip regulator consists of two elements,
the main regulator, and the low voltage reset circuit. The VDD
regulator accepts an unregulated input supply and provides a
regulated VDD supply to all digital sections of the device. The
output of the regulator is also connected to the VDD pin to
provide the 5.0 V to the microcontroller.

Watchdog Timer
WATCHDOG TIMER
a watchdog timeout or wrong watchdog timer reset. A
watchdog reset event will reset all registers in the SPI,
excluding the RSR.
RESET, IRQ & WAKE-UP
generate a reset or wake-up signal to the core IC. There is a
pin that is used to detect an external wake-up event. The
Reset signal has many possible sources in the Analog IC
circuitry. The IRQ function on the Analog IC will notify the
core IC of pending system critical conditions.
The watchdog timer module generates a reset, in case of
