object. The x-axis represents the time and the y-axis is the numerical representation of the analog quantity. The y-scale on the
left side of the graph area is fixed (0-2500 mV). It corresponds to the AD0, AD1, and AD2 inputs - these are 2.5 V analog inputs.
The y-scale on the right side is changed based on the currently displayed quantity (input voltage, chip temperature, current, or
value of Lx input). The values of analog inputs AD0, AD1, and AD2 can be displayed at the same time. The other quantities can
only be displayed exclusively. Analog inputs L0-L5 are displayed exclusively, and the user can switch the range from between 0
to 5.0 V and 0 to 18 V. The history of the sensed quantities is kept in the memory (200 points), so even if the value is currently
not displayed, it is not lost.
of the current sense resistor placed on the board, the value of the current is listed in raw ADC units, instead of amps. The
amplification of the voltage over the current sense resistor is set to 7 times (this is the default value after reset). When there is
no communication between the PC and the target, the ADC display is temporarily disabled.

disabled. All values from the registers and variables are cleared, because the device wakes up from the SLEEP mode
transitioning the power-on reset. The STOP mode is the low power mode with higher current consumption than the SLEEP mode.
In STOP mode, the 5.0 V and 2.5 V regulator are working with limited current capability. The jumpers JP4 and JP9 must be
removed, otherwise, a reset will be triggered (caused by high current consumption of LEDs) and the device will be immediately
awakened from the STOP mode.

This frame covers the largest area on the control page, due to the graphical display of sensed analog values in the graph
There is also a numerical value displayed for battery voltage, temperature, and load current. Since there is not a fixed value
The MM912H634 allows two low power modes. While the device is in the SLEEP mode, the 5.0 V and 2.5 V regulators are
There are several options to wake-up the device from the low power modes, supported by the application:
• Forced wake-up - there is a fixed time during which the device is in low power mode
• Wake-up by LIN module
• External reset (reset button SW1) - only from STOP mode
