PRODUCTION DATA
If at any time the supply voltage falls below the undervoltage lockout threshold voltage (VUVLO), all MOSFETs in the H-bridge will be disabled. The charge pump and device logic are disabled in this condition. Normal operation resumes when the supply voltage rises above the VUVLO threshold. Table 8-7 summarizes the conditions when the device enters UVLO.
VVM | Device response |
---|---|
<4.5 V | UVLO |
>4.5 V | Normal operation |
