American Technical Support: 800-282-9855 Web Site: www.cherry–semi.com 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 multi- plexed system. Digital input control eliminates the need for any analog cali- bration of the gauge. The controlling microprocessor sends out a PWM signal to each H bridge driver input (IN1, IN2). The PWM sig- nal duty cycle is proportional to the H–bridge output. Output current (100mA max) direction is controlled by the DIRECTION input. PWM switch- ing 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.
