Supply Voltage: 5 V supply. A ceramic capacitor as close as possible to
GND is recommended.
High-side-driver output 9: the output is built by a high side switch and is
intended for resistive loads; hence the internal reverse diode from GND to
the output is missing. For ESD reason a diode to GND is present but the
energy which can be dissipated is limited. The high-side driver is a power
DMOS transistor with an internal parasitic reverse diode from the output
to VS (bulk-drain-diode). The output is over current and open load
protected.
PWMH input: this input signal can be used to control the H-Bridge Gate
drivers
ECDR: using the device in EC control mode this pin is used to control the
Gate of an external MOSFET.
High side driver output 8: see OUT9
Important: This output can be configured to supply a bulb with low on-
resistance or a LED with higher on-resistance in a different application.
High-side-driver-output 10: see OUT9
Important: Beside the OUT10-HS on/off bit this output can be switched on
setting the ECON bit for electrochrome control mode with higher priority.
ECFD: using the device in EC control mode this pin is used as “virtual
GND” for the EC-glass. For EC-glasses, that require a negative discharge
voltage, this supplies the fast discharge voltage. If no EC-glass is used,
this pin must be connected to ground.
ECV: using the device in EC control mode this pin is used as voltage
monitor input. For fast discharge an additional low-side-switch is
implemented.
