FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
Figure 24. Inrush Current Limitation on HS Outputs
High-Side Current Recopy
Each High-Side has an additional sense output to allow a
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
The HVDD terminal is a switchable 5V output terminal. It
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
The output is protected against over temperature
conditions.
HVDD Over Current Protection
The HVDD output is protected against overcurrent. In case
the current reach the overcurrent limit, the output current will
be limited and the HVDDOCF overcurrent flag in the System
Status register is set.
High-Side Out Register (HSOUT)
HVDD-ON — HVDD On Bit
This read/write bit enables the HVDD output.
Reset clears HVDDON bit.
1 = HVDD enabled
0 = HVDD disabled
HSxON — High-Side on/off Bits
These read/write bits turn on the High-Side Fet’s
permanently
Reset clears the HSxON bits.
1 = High-Side x is turned on
0 = High-Side x is turned off
