Usage Precautions
•
•
•
Although the TB6559FG contains overcurrent detection circuitry, a large current might abruptly flow through
the IC in case of a short-circuit to power supply, a short-circuit to ground or a short-circuit across the load,
damaging the device permanently. This possibility should be fully considered in the design of the output, V
and ground lines. If the device is damaged, a large current might continually flow through the device as a
secondary effect. Therefore, Toshiba recommends that a fuse be connected to the power supply line.
Install this IC properly. If not, (e.g., installing it in the wrong position), the IC might be broken.
If external components are shorted together, the IC might be broken.
