diode limits the supply to 18V. When the MIC5011 is off,
power is supplied by a diode connected to a 15V supply. The
circuit of Figure 5 is put to good use as a barrier between
low voltage control circuitry and the 90V motor supply.
Half-Bridge Motor Driver (Figure 8). Closed loop control
of motor speed requires a half-bridge driver. This topology
presents an extra challenge since the two output devices
should not cross conduct (shoot-through) when switching.
Cross conduction increases output device power dissipa-
tion. Speed is also important, since PWM control requires
the outputs to switch in the 2 to 20kHz range.
The circuit of Figure 8 utilizes fast con?gurations for both
the top- and bottom-side drivers. Delay networks at each
input provide a 2 to 3μs dead time effectively eliminating
cross conduction. Two of these circuits can be connected
together to form an H-bridge for locked antiphase or sign/
magnitude control.
