VOLTAGE MEASUREMENT

Battery voltage is measured every 440ms on the V

IN

pin with respect to V

SS

. Measurements have a 0 to 4.99V

range and a 4.88mV resolution. The value is stored in the voltage register in two’s complement form and is updated
every 440ms. Voltages above the maximum register value are reported at the maximum value; voltages below the
minimum register value are reported at the minimum value.
