Figure 25. EC Circuitry
EC Open Load Detection
Open Load can be detected by setting ECOLT. A small
current source sources a typical 200
μA on the EC pin, and
the voltage on the pin is measured. If the voltage is above the
typical 2.0V (typical 10K threshold), the ECOLF bit in the EC
Status and Control Register ECSCTL is set, indicating the
open load condition.
If the Open load circuitry is activated (ECOLT=1), the EC
glass is disabled.
EC Short Circuit Protection
The EC output is protected against shorts to VSUP. In
case of a short-circuit, the ECOCF in the EC Status and the
Control Register (ECSCTL) are set, and the EC circuitry is
disabled.
The EC output is protected against shorts to GND. In case
of a short-circuit, the ECOCF in the EC Status and the
Control Register (ECSCTL) are set, and the EC circuitry is
disabled.
EC Digital to Analog Converter
The EC output, and therefore the voltage on the EC glass
are controlled. The EC glass circuitry has a 6 bit D/A
converter to control the output voltage between 0 and 1.4V.
EC D/A Converter Control Register (ECDACC)
ECDAx — Digital to Analog Bits
These read/write bits set the output voltage on the EC pin.
