PRODUCTION DATA
If at any time the supply voltage falls below the undervoltage lockout threshold voltage, all MOSFETs in the H-bridge will be disabled. The charge pump and device logic are disabled in this condition. When powered by split supplies (DSG package only), the UVLO triggers when the VCC pin voltage drops below VUVLO,VCC falling threshold. This allows the VM supply to dip all the way to 0 V. When operating from a single supply (DRL package only), the UVLO triggers when the VM pin voltage drops below VUVLO,VM falling threshold. Normal operation resumes when the supply voltage rises above the VUVLO rising threshold. Table 8-6 summarizes the conditions when the device enters UVLO.
Package variant | VVM | VVCC | Device response |
---|---|---|---|
DSG | 0 V to VVM_MAX | <1.65 V | UVLO |
0 V to VVM_MAX | >1.65 V | Normal operation | |
DRL | <1.65 V | N/A | UVLO |
1.65 V to VVM_MAX | N/A | Normal operation |
