Four-phase drive circuit
Source: InternetPublisher:spectrum Keywords: Driver circuit FET Updated: 2021/10/07
LS7261/LS7262 can also be used to control
four-phase brushless DC motors . At this time, both CS1 and CS2 are taken
to be . , two orthogonal Hall sensor signals are input from the Sl and S2 pins, and
short-circuit S3 and S2. Figure 3-8 shows a four-phase motor drive connection diagram
using transistors or FETs
, and also
shows current detection and braking control
.
