Table 16
Failure Mode     Effect (1)    
1     COUT Open     COUT error, output turned off    
2     RET (active) Open     COUT error, output turned off    
3     RET (passive) Open     Not detected, will not influence function    
4     COUT shorted to RET (active)     COUT error, output turned off (2)    
5     COUT shorted to RET (passive)     Not detected, will not influence function    
6     COUT shorted to +BAT     COUT error, output turned off    
7     COUT shorted to -BAT     COUT error, output turned off (2)    
8     RET (active) shorted to +BAT     COUT error, output turned off (2)    
9     RET (active) shorted to -BAT     COUT error, output turned off    
10     RET (passive) shorted to +BAT     Not detected, will not influence function    
11     RET (passive) shorted to -BAT     COUT error, output turned off    
12     COUT shorted to 2:nd COUT (passive)     Not detected, will not influence function    
13     COUT shorted to 2:nd RET (active)     COUT error, output turned off (2)    
14     COUT shorted to 2:nd RET (passive)     Not detected, will not influence function    
15     RET shorted to 2:nd RET (active)     COUT error, output turned off    
16     RET shorted to 2:nd RET (passive)     Not detected, will not influence function    
17     Insufficient voltage     COUT error, output turned off    
( 1 ) Turning off outputs are controlled by CAN master and therefore delayed by maximum 2 bus cycles. If local error handling is enabled, the output will turn off locally without delay.
( 2 ) Turned off by integrated protection functions in IC.Failure Modes in PWM Mode

2     L-side (active) Open     PWMOUT error, output turned off    
3     L-side (passive) Open     Not detected, will not influence function    
4     H-side shorted to L-side (active)     PWMOUT error, output turned off (2)    
5     H-side shorted to L-side (passive)     Not detected, will not influence function    
6     H-side shorted to +BAT     PWMOUT error, output turned off    
7     H-side shorted to -BAT     PWMOUT error, output turned off (2)
