1A H-Bridge Stepper Motor Driver
Description
CS3717A
The CS3717A controls and drives
one phase of a bipolar stepper
motor with chopper control of the
phase current. Current levels may
be selected in three steps by means
of two logic inputs which select one
of three current comparators. When
both of these inputs are high the
device is disabled. A separate logic
input controls the direction of cur-
rent flow. A monostable, pro-
grammed by an external RC net-
work, sets the current decay time.
The power section is a full H-bridge
driver with four internal clamp
diodes for current recirculation. An
external connection to the lower
emitters is available for the inser-
tion of a sensing resistor. Two
CS3717As and several external
components form a complete step-
per motor drive subsystem.
The recommended operating ambi-
ent temperature range is from 0 to
70C.
The CS3717A is supplied in a 16
lead PDIP.
