Control Register
The MX881 control register is a 5 bit register that allows the user to program the maximum output
voltage and the maximum average battery current during the charge cycle. Table1 shows how the bits in
the control register are assigned. ABC(2:0) are used to set the average battery current and OVS(1:0) are
used to set the output voltage selection reference.

Output Voltage Selection
The MX881 limits the high voltage placed on the external capacitor by comparing a divided down version
of the secondary flyback voltage to an internal voltage. This internal voltage is programmable to 4
discrete values to allow the user to change the flash energy. The external voltage divider ratio needed to
obtain 330V maximum output voltage should be 269 to 1. This external resistor divider network is also
used to form a low pass filter with an internal capacitor so it is important that the equivalent resistance of
the voltage divider network be 3K ohms. Table 2 shows the internal reference values used for possible
values of the capacitor charge voltage. The default value is 11.
