○ Cautions on use

Absolute maximum ratings

An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down the

devices, thus making impossible to identify breaking mode, such as a short circuit or an open circuit. If any over rated values will expect

to exceed the absolute maximum ratings, consider adding circuit protection devices, such as fuses.

GND and PGND potential

Ensure a minimum GND and PGND(Except for SW pin and VC pin) pin potential in all operating conditions. In addition, ensure that

no pins other than the GND and PGND pin carry a voltage less than or equal to the GND and PGND pin, including during actual

transient phenomena.

Don’t use VC pin under Absolute Maximum Rating.

Thermal design

Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions.

Protect circuit

The IC does not incorporate built-in malfunction protection such as overcurrent protection, short detection, or thermal shutdown

circuitry. For this reason, the IC may be damaged if it is shorted or subjected to a load that exceeds the package power. The

design of peripheral application circuits should reflect these potential risks.

Inter-pin shorts and mounting errors

Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any connection

error or if positive and ground power supply terminals are reversed. The IC may also be damaged if pins are shorted together or

are shorted to other circuit’s power lines.

Common impedance

The power supply and ground lines must be as short and thick as possible to reduce line impedance. Fluctuating voltage on the

power ground line may damage the device.

IC Pin Input

This is the monolithic IC and has P

isolation and P substrate for element isolation between each element. By the P layer and N

layer of each element, a P-N junction is formed and various parasitic elements are configured.

For example, in the case of a resistor and transistor being connected to a pin as shown in Fig.-3;

P-N junction operates as a parasitic diode when GND > (Pin A) in the case of the resistor, and when GND > (Pin B) in the case of

the transistor (NPN)

Also, a parasitic NPN transistor operates by the N layer of another element adjacent to the previous diode in the case of a

transistor (NPN) when GND > (Pin B).

The parasitic element consequently emerges through the potential relationship because of IC’s structure. The parasitic element

pulls interference out of the circuit which may be the cause of malfunction or destruction. Therefore, excessive caution is

required to avoid operation of the parasitic element which is caused by applying voltage to an input pin lower than GND (P board),

etc.
