PRODUCTION DATA
If at any time the voltage on the VM pin falls below the UVLO falling threshold voltage, VUVLO, all circuitry in the device is disabled, and all internal logic is reset. Operation resumes when VVM rises above the UVLO rising threshold. The nFAULT pin is driven low during an undervoltage condition and is released after operation has resumed.
FAULT | ERROR REPORT | H-BRIDGE | INTERNAL CIRCUITS | RECOVERY |
---|---|---|---|---|
VM undervoltage (UVLO) | nFAULT unlatched | Disabled | Shut down | System and fault clears on recovery |
Overcurrent (OCP) | nFAULT unlatched | Disabled | Operating | System and fault clears on recovery and motor is driven after time, tRETRY |
Thermal shutdown (TSD) | nFAULT unlatched | Disabled | Operating | System and fault clears on recovery |
