TM CA3282 Octal Low Side Power Driver with Serial Bus Control Description The CA3282 is a logic controlled, eight channel octal power driven. The serial peripheral interface (SPI) utilized by the CA3282 is a serial synchronous bus compatible with Intersil CDP68HC05, or equivalent, microcomputers. 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. Each output channel has separate output latch control with fault unlatch and diagnostic feedback. 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.
