About Brushless DC Motors (brochure)
... In general, BLDC motors have three phase windings. The easiest way is to power two of them at a time, using Hall sensors to know the rotor position. A simple logic allows for optimal energizing of the phases as a function of rotor position, just like the commutator and brushes are doing in the conve ...

AP7173 1.5A LOW DROPOUT LINEAR REGULATOR WITH PROGRAMMABLE SOFT-START
... Power-Good pin, open-drain output. When the VOUT is below the PG threshold the PG pin is driven low; when the VOUT exceeds the threshold, the PG pin goes into a high-impedance state. To use the PG pin, use a 10kΩ to 1MΩ pull-up resistor to pull it up to a supply of up to 5.5V, which can be higher t ...
