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 over-volt-

age and over-current. Each output channel has separate

output latch control with fault unlatch and diagnostic feed-

back. 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 respec-

tive output driver is unlatched. In addition, over current pro-

tection 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 volt-

age, 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.
