DESCRIPTION
As shown in the Block Diagram for the CA3282 each of the open drain NDMOS output drivers has individual protection for overvoltage and over-current. Under normal ON conditions, each output driver is in a low, saturation state. Comparators in the diagnostic circuitry monitor the output drivers to determine if an out of saturation condition exists. If a comparator senses a fault, the respective output driver is unlatched. In addition, over current protection is provided with current limiting in each output, independent of the diagnostic feedback loop. The CA3282 is fabricated in a Power BiMOS IC process, and is intended for use in automotive and other applications having a wide range of temperature and electrical stress conditions. It is particularly suited for driving lamps, relays, and solenoids in applications where low operating power, high breakdown voltage, and high output current at high temperatures is required. The CA3282 is supplied in 15 lead plastic SIP package with lead forms for either vertical or surface mount.
