CS3717A General Description
The CS3717A 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 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 CS3717AÕs and several external components form a complete stepper motor drive subsystem.
The recommended operating ambient temperature range is from 0 to 70¡C.
The CS3717A is supplied in a 16 lead PDIP.

CS3750 General Description
The CS3750 is a dual H-bridge four quadrant air-core gauge driver. The IC provides all the functions necessary to drive a tachometer or speedometer as part of a microprocessor based multiplexed system. Digital input control eliminates the need for any analog calibration of the gauge.
The controlling microprocessor sends out a PWM signal to each H bridge driver input (IN1, IN2). The PWM signal duty cycle is proportional to the HÐbridge output. Output current (100mA max) direction is controlled by the DIRECTION input. PWM switching noise is minimized at each half bridge by an internal RC filter and external programmable capacitor.
The CS3750 is protected against 50V load dump, over voltage and thermal runaway fault conditions. Any of these faults causes the IC to shut down. Each high side of the output driver is current limited. A short circuit condition in one driver does not affect the others.
