SNOSDC0A October 2020 – December 2020 LM7310
PRODUCTION DATA
The following table summarizes the LM73100 response to various fault conditions.
Event | Protection Response | Fault Latched Internally |
---|---|---|
Overtemperature | Shutdown | Y |
Undervoltage (UVP or UVLO) | Shutdown | N |
Input Reverse Polarity | Shutdown | N |
Overvoltage | Shutdown | N |
Reverse Current | Reverse Current Blocking | N |
Transient overcurrent during steady state | Shutdown | Y |
Faults which are not latched internally are automatically cleared once the trigger condition goes away and thereafter the device recovers without any external intervention. Faults which are latched internally can be cleared either by power cycling the part (pulling VIN to 0 V and then above VUVP(R)) or by pulling the EN/UVLO pin voltage below VSD(F).
After a latched fault, pulling the EN/UVLO just below the UVLO threshold (VUVLO(F)) has no impact on the device.
