PBL3717 PBL3717A DIP16 (12+2+2pin) STMicroelectronics

STEPPER MOTOR DRIVER
ENCAPSULADO Powerdip 12 + 2 + 2 (Plastic Package)
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 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 deviceis 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 raccomended operating ambient temperaturer anges is from 0 to 70°C. The PBL3717A is supplied in a 12 + 2 + 2 lead Powerdip package
