Multiple devices can be cascaded for a dot or bar mode display with a range of 60 or 90 dB. LM3915s can also be cascaded
that in the 2-phase the current is flowing on one winding while the other winding is turned off/idle at every commutation. Due to the square wave BEMF pattern, the motor commutation sequence on the single or two-phase BLDC motor can be implemented the instant the BEMF changes its state or a rising/falling

The devices can be placed into power-down (PWR_DN) mode by pulling the RST/PD pin to a logic low state for at least 400 ns. The RST/PD pin is asynchronous to the clock; thus, RST/PD can be triggered at any time regardless
input signal increases, a comparator will switch on another indicating LED. This resistor divider can be connected between any 2 voltages, providing that they are 1.5V below V+ and no less than V−. If an expanded scale meter display is desired, the total divider voltage can be as little as 200mV. Expanded-scale meter displays are more accurate and the segments light uniformly only if bar mode is used. At 50mV or more per step, dot mode is usable. [/code]
