Page 1
... The CS1112 is a Power Output Driver. The IC incorporates four protected DMOS low–side drivers designed to drive inductive and resistive loads in an automotive environment. The outputs are controlled by an 8–bit serial peripheral interface (SPI) or its associated parallel input. Each output contains overcurrent protection, open load detection, and inductive flyback clamps ...

... Typical Operation Control of the CS1112 can be done using the Serial Peripheral Interface (SPI) port using the Data Input information in Table 1, or the outputs can be controlled via the parallel inputs (IN0, IN1, IN2, IN3). IN0 controls OUT0, IN1 controls OUT1, IN2 controls OUT2, and IN3 controls ...

... CIRCUIT DESCRIPTION The CS1112 was developed for use in very noisy and very harsh environments such as seen in an automobile system. The device has four low–side switches all controlled through an 8–bit Serial Peripheral Interface (SPI) port. Control of the outputs is also OR’d with parallel inputs. This ...

... The use of the SPI also allows the integrated circuit to communicate directly with the microprocessor. While designed for an automotive environment, the CS1112 can be used in other applications in the computer market, industrial market, telecommunications market, or any other instance where numerous drivers are needed. All ...

... FAULT MODE OPERATION The CS1112 provides protection for a multitude of system faults and conditions. These include Overvoltage, Current Limit, Open Circuit, Output Short to Power, Output Short to Ground, and Flyback Clamp. Overvoltage The IC is constantly monitoring the voltage on the V pin. If the voltage on this pin exceeds the Overvoltage Shutdown Threshold (typically 35 V), all outputs immediately turn off ...
