DESCRIPTION
The PBL3717A is a monolithic IC which 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 compara-
tors. When both of these inputs are high the device
is disabled. A separate logic input controls the direc-
tion of current flow.
A monostable, programmed 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 insertion of a sensing resistor. Two
PBL3717As and few external components form a
complete stepper motor drive subsystem.
The raccomended operating ambient temperature
ranges is from 0 to 70
°C.
The PBL3717A is supplied in a 12 + 2 + 2 lead Pow-
erdip package.
