BD8621EFV
Technical Note
Protecting BUS function with terminal PDET
The terminal PDET (3 pins) monitors whether IC is normal or not. When IC becomes abnormal, the PDET output is reduced
at "L" level with the output voltage fixed “L” level at the same time. Moreover, it is possible to make the output fix in a low
level by compulsorily reducing the terminal PDET at "L" level from the outside.
When two or more BD8621EFV is used in the application, this function prevents the IC from destroying, because one IC
error transmits all other ICs by PDET line in the condition that PDET terminals are connected each other.
Fig.6 Protecting BUS communication
※ Please give the terminal PDET as OPEN when you do not use protecting BUS function.
Error detection (off latch) release method
BD8621EFV enters the state of an off latch when the protection function operates.
To release the off latch state, EN terminal voltage should be changed to low level once time.
