Article How can I change the Cell Undervoltage Threshold UV_VCVTH value of MAX14921?

The Cell Undervoltage Threshold, UV_VCVTH, is fixed at +1.5V (typ), +1.4V (min) and +1.6V (max).  There is no user-programmable option to change this value.  The Cell Undervoltage Threshold only serves to set a bit in the monitoring bits diagnostics when the cell voltage drops below UV_VCVTH.  The device still accurately measures cell voltages from 4.5V down to 0.5V (Differential Input Signal Range), and the user can monitor for a specific cell undervoltage value in firmware for the microcontroller.
