Stepper Motor Driver
DESCRIPTION
The PBL3717A is amonolithic IC which controls and
drives one phase of a bipolar stepper motor with
chopper control of the phase current. Current levels
maybe 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 current flow.
A monostable,programmed by an external RC network,
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 reccomended operating ambient temperature
ranges is from 0 to 70 °C.
