* TJ3964 can deliver a continuous current of 1A over the full operating temperature. However, the output

current is limited by the restriction of power dissipation which differs from packages. A heat sink may be

required depending on the maximum power dissipation and maximum ambient temperature of application.

With respect to the applied package, the maximum output current of 1A may be still undeliverable.

of the Pull-Up resistor should be kept under 10kΩ.

* See Application Information.
