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. 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.
