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 CS3717AÕs and several external components form a complete step- per motor drive subsystem. The recommended operating ambi- ent temperature range is from 0 to 70¡C. The CS3717A is supplied in a 16 lead PDIP.
