Figure 5: Connections and Component Values as in Figure 6.
The UC3717 drive circuit shown in the block diagram in-
cludes the following functions:
(1) Phase Logic and H-Bridge Output Stage
(2) Voltage Divider with three Comparators for current control
(3) Two Logic inputs for Digital current level select
(4) Monostable for off time generation
Input Logic: If any of the logic inputs are left open, the
circuit will treat it as a high level input.
Phase Input: The phase input terminal, pin 18, controls
the direction of the current through the motor winding.
The Schmidt-Trigger input coupled with a fixed time de-
lay assures noise immunity and eliminates cross conduc-
tion in the output stage during phase changes. A low
level on the phase input will turn Q2 on and enable Q3
while a high level will turn Q1 on and enable Q4. (See
Figure 7).
Output Stage: The output stage consists of four Dar-
lington transistors and associated diodes connected in
an H-Bridge configuration. The diodes are needed to pro-
vide a current path when the transistors are being
switched. For fast recovery, Schottky diodes are used
FUNCTIONAL DESCRIPTION
across the source transistors. The Schottky diodes allow
the current to circulate through the winding while the sink
transistors are being switched off. The diodes across the
sink transistors in conjunction with the Schottkys provide
the path for the decaying current during phase reversal.
(See Figure 7).
