raised to 2.03 V by a hysteresis of 0.03 V.
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.
Electrical Characteristics

whether they are provided with hysteresis.
The TB6608FNG includes an undervoltage lockout circuit, which puts the output transistors in the
The output transistors are automatically turned on when V
Even when UVLO circuit is tripped, internal circuitry continues to operate in accordance with the CK input like
