... 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 ...

... An on-chip clamp circuit capable of handling 500mA is provided at each output for clamping inductive loads. RESET - Active low reset input. When this input line is low, the shift register and output latches are configured to turn off CA3282 (3) (1) (13) (12) ...

... Serial output and input data are simultaneously trans- ferred to and from the SPI bus. The parallel outputs are latched into the output latch in the CA3282 at the end of a data transfer. The parallel inputs jam diagnostic data into the shift register at the beginning of a data transfer cycle. ...

... ON, and a logic one will turn it OFF. CE Low to High Transition When the last data bit has been shifted into the CA3282, the CE pin should be pulled high. At the rising edge of CE, shift register data is latched into the output latch and the outputs are activated with the new data ...

... For the CA3282, the maximum positive output current rating is 1A when one output is ON. When ALL outputs are ON, the rating is reduced to 0.625A because the total maximum cur- rent is limited to 5A. For any given application, all output drivers on a chip may or may not have a different level of loading ...
