Undervoltage Lockout Circuit（UVLO）

The TB6674 incorporates an under voltage lockout circuit.

Outputs are turned off (Hi-Z) under the conditions as follows;

VCC ≤ 4.0 V (Design target) or

VS1A ≤ 6.0 V (Design target) and VS1B ≤ 6.0 V (Design target) or

VS2A ≤ 2.2 V (Design target)

The UVLO circuit has a hysteresis and the function recovers under the conditions as follows;

VCC = 4.1 V (Design target), VS1A/ VS1B = 6.5 V (Design target), VS2A = 2.3 V (Design target)
