FUNCTIONAL DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
SMARTMOS ANALOG CONTROL IC
INTERNAL REGULATORS & SAFETY:
VOLTAGE REGULATION
The voltage regulator circuitry provides the regulated
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 5.0V to the microcontroller.
SWITCHED VDD
This function provides a switchable +5.0V VDD rail for an
external load.
WATCHDOG TIMER
The watchdog timer module generates a reset, in case of
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
There are several functions on the Analog IC that can
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.
CONTROL & INTERFACE:
HALL SENSOR INTERFACE
This interface can be configured to support an input pin as
a general purpose input, or as a hall-effect sensor input, to be
able to read 3-pin / 2-pin hall sensors or switches.
