Instructions

1) Protection circuit

Overcurrent Protection Circuit

Built-in overcurrent protection circuit corresponding to current capacity prevents damage when IC is damaged

is a load short circuit. This protection circuit is a "7" shaped current control circuit designed so that the current is

Even if large current flows instantaneously through high capacitance, it will not be limited and will not latch up

capacitor. However, although this protection circuit is effective in preventing damage due to accidents,

It is not suitable for continuous operation or brief use. When creating a thermal design, keep in mind

The overcurrent protection circuit has a negative current capacity characteristic with respect to temperature (see Figure 4 and

16).

Thermal Shutdown Circuit (Thermal Protection)

The system has built-in temperature protection circuitry designed to protect the IC from thermal damage. like

As shown above, it must be used within the acceptable loss, but if the acceptable loss happens to be

If this temperature is continuously exceeded, the chip temperature Tj will rise, thus making the temperature protection circuit work.

When the thermal shutdown circuit operates, the operation of the circuit will be suspended. circuit resumes operation

Effective immediately after the chip temperature Tj decreases, so the output repeats the ON and OFF states (see

The operating temperature of the thermal protection circuit is shown in Figures 12 and 24.

In some cases, ICs can be damaged by thermal runaway when they are in an overloaded state. be sure

Avoid overloading the IC.

reverse current

To prevent damage to the IC when reverse current flows through the IC, it is recommended to use a diode

Place it between Vcc and Vo and create a path so the current can escape (see Figure 34).
