High-Side Current Recopy
current recopy feature. This sense source is internally
connected to a shunt resistor. The drop voltage is amplified
and switched to the Analog Multiplexer.
Switchable HVDD Outputs
can be used for driving external circuitry which requires a 5V
voltage. The output is enabled with bit PSON in the System
Control register and can be switched on / off with bit
HVDD_ON in the High-Side Out register. Low or high voltage
conditions (LVIF / HVIF) will have no influence on this
circuitry.
HVDD Over Temperature Protection
conditions.
HVDD Over Current Protection
the current reach the overcurrent limit, the output current will
be limited and the HVDDOCF overcurrent flag in the System
Status register is set.
