FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
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 pin is a switchable 5V output pin. It can be used
for driving external circuitry which requires a 5V voltage. The
output is enabled with the PSON bit in the System Control
register and can be switched on / off with the HVDD_ON bit
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 over-current. In
case the current reach the over-current limit, the output
current will be limited and the HVDDOCF over-current 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
the HVDDON bit.
1 = HVDD enabled
0 = HVDD disabled
HSxON — High Side on/off Bits
These read/write bits turn on the High Side FETs
permanently. Reset clears the HSxON bits.
1 = High Side x is turned on
0 = High Side x is turned off
HSxPWM — High Side PWM on/off Bits
These read/write bits enable the PWM control of the High
Side FETs. Reset clears the HSxPWM bits.
1 = High Side x is controlled by PWM input signal
0 = High Side x is not controlled by PWM input signal
High Side Status Register (HSSTAT)
HSxOCF — High Side Overcurrent Flag Bit
This read/write flag is set by an over-current condition at
the high side drivers x. Clear HSxOCF and enable the HS
Driver by writing a logic [1] to HSxOCF. Writing a logic [0] to
HSxOCF has no effect. Reset clears the HSxOCF bit.
1 = over-current condition on high side drivers has
occurred
0 = no over-current condition on high side drivers has
occurred
HVDDOCF — HVDD Output Over-current Flag Bit
This read/write flag is set by an over-current condition at
the HVDD pin. Clear HVDDOCF and enable the output by
writing a logic [1] to the HVDDOCF Flag. Writing a logic [0] to
HVDDOCF has no effect. Reset clears the HVDDOCF bit.
1 = over-current condition on VDD output has occurred
0 = no over-current condition on VDD output has
occurred
Electrochrome Circuitry
The EC glass is controlled by two transistors. T1 switches
the EC glass on/off, and T2 controls the EC output voltage
given by the 6Bit DA Converter.
