● Operational Notes
1) Protection Circuits
Overcurrent Protection Circuit
A built-in overcurrent protection circuit corresponding to the current capacity prevents the destruction of the IC when there
are load shorts. This protection circuit is a “7”-shaped current control circuit that is designed such that the current is
restricted and does not latch even when a large current momentarily flows through the system with a high-capacitance
capacitor. However, while this protection circuit is effective for the prevention of destruction due to unexpected accidents,
it is not suitable for continuous operation or transient use. Please be aware when creating thermal designs that the
overcurrent protection circuit has negative current capacity characteristics with regard to temperature (Refer to Fig.4 and
16).
Thermal Shutdown Circuit (Thermal Protection)
This system has a built-in temperature protection circuit for the purpose of protecting the IC from thermal damage. As
shown above, this must be used within the range of acceptable loss, but if the acceptable loss happens to be
continuously exceeded, the chip temperature Tj increases, causing the temperature protection circuit to operate.
When the thermal shutdown circuit operates, the operation of the circuit is suspended. The circuit resumes operation
immediately after the chip temperature Tj decreases, so the output repeats the ON and OFF states (Please refer to
Fig.12 and 24 for the temperatures at which the temperature protection circuit operates).
There are cases in which the IC is destroyed due to thermal runaway when it is left in the overloaded state. Be sure to
avoid leaving the IC in the overloaded state.
Reverse Current
In order to prevent the destruction of the IC when a reverse current flows through the IC, it is recommended that a diode
be placed between the Vcc and Vo and a pathway be created so that the current can escape (Refer to Fig.34).
2) This IC is bipolar IC that has a P-board (substrate) and P+ isolation layer
between each devise, as shown in Fig.35. A P-N junction is formed between
this P-layer and the N-layer of each device, and the P-N junction operates as a
Reverse current
parasitic diode when the electric potential relationship is GND> Pin A, GND>
Pin B, while it operates as a parasitic transistor when the electric potential
relationship is Pin B GND> Pin A. Parasitic devices are intrinsic to the IC. The

operation of parasitic devices induces mutual interference between circuits,
causing malfunctions and eventually the destruction of the IC itself. It is
necessary to be careful not to use the IC in ways that would cause parasitic
elements to operate. For example, applying a voltage that is lower than the
GND (P-board) to the input terminal.
