Undervoltage Lockout (UVLO) Circuit
The TB6608FNG includes an undervoltage lockout circuit, which puts the output transistors in the
high-impedance state when VCC decreases to 2.0 V (typ.) or lower.
The output transistors are automatically turned on when VCC increases past the lockout threshold, which is
raised to 2.03 V by a hysteresis of 0.03 V.
Even when UVLO circuit is tripped, internal circuitry continues to operate in accordance with the CK input like
when ENABLE is set Low. Thus, after the TB6608FNG exits the UVLO mode, the RESET signal should be asserted
for putting the TB6608FNG in the Initial state if necessary.
