ThePBL3717Ais amonolithic ICwhich controlsand drives one phase of a bipolar stepper motor with chopercontrolof the phase current. Current levels maybeselected in threestepsbymeans of two logic inputs which select one of three current comparators of PBL3717A. When both of these inputs are high the device is disabled.A separatelogic input controls the direction of current flow.
A monostable of PBL3717A,programmed by an externalRC network, sets the current decay time.
The power section is a full H-bridge driver with four internal clamp diodes for current recirculation. An externalconnectionto theloweremitters isavailable 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 of PBL3717A is from 0 to 70 .
The PBL3717Ais supplied in a 12 + 2 + 2 lead Powerdip package.
