... NCV7608 Octal Configurable Low/High Side Driver The NCV7608 integrates 8 output drivers configurable in any combination of high−side, low−side, or H−Bridge configurations. The integrated standard Serial Peripheral Interface (SPI) allows digital control of all output stages and provides diagnostic fault information. In addition, four channels (#5−8) can be PWM controlled via external control input pins. Integrated clamping circuits (both in high and low− ...

... The device provides a 16 bit SPI−interface. Data is imported into the NCV7608 through the SI (serial input) pin. Data is exported out of the NCV7608 through the SO (serial output) pin. The input−frame (SI) is used to command the output stages and program individual channel open load diagnostics. channel− ...

... SPI output bits #9−12. When overcurrent or thermal shutdown fault occurs, bits 9 through 12 record the state of INx. This enables the user to distinguish an open load fault from an over current fault when the NCV7608 is operated from two isolated controllers for the SPI input and the Parallel input. ...

... Supply Fail Fault Reported on SO Fault Filters The NCV7608 detects overtemperature, over current, VS Power Supply and open load faults. Faults are reported in the Output Data fault register. The fault filter timer for over current or open load is 100 ms (typ). An over current or open load event must exist for this period of time to be recognized ...

... Bringing the CSB pin from condition immediately displays the information on the output data bit 0, thermal warning, even in the absence of a SCLK signal. As the temperature of the NCV7608 changes from a condition from below the thermal warning threshold to above the thermal warning threshold, the state of the SO pin changes and this level is available immediately when the CSB goes to 0 ...

... A low on EN will result in a power−on−reset to the logic. All outputs will be shut off and all registers reset. Loss of Ground The NCV7608 output drivers will not be active during a loss of ground condition. No damage to the device will occur during this condition for VS less than or equal ...
