7.3.8 Undervoltage Protection

The DRV10974 device has an undervoltage lockout feature, which prevents motor operation whenever the supply voltage (VCC) becomes too low. Upon power up, the DRV10974 device operates when VCC rises above V(UVLO_F) + Vhys(UVLO). The DRV10974 device continues to operate until VCC falls below V(UVLO_F).
