All units feature integral clamp diodes for switching inductive loads. Applications include relay, hammer, lamp and display LED drivers. The suffix G appended to the part number represents a Lead Pb -Free product. ICEX 2. IIN ON 4. VIN ON 6. VF 5 8. Precautions for Using This IC does not include built-in protection circuits for excess current or overvoltage. If this IC is subjected to excess current or overvoltage, it may be destroyed.
Hence, the utmost care must be taken when systems which incorporate this IC are designed. Equivalent Circuits The equivalent circuit diagrams may be simplified or some parts of them may be omitted for explanatory purposes. Test Circuits Components in the test circuits are used only to obtain and confirm the device characteristics.
These components and circuits are not guaranteed to prevent malfunction or failure from occurring in the application equipment. IC Usage Considerations Notes on Handling of ICs 1 The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded, even for a moment. Do not exceed any of these ratings. Exceeding the rating s may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion.
The IC will fully break down when used under conditions that exceed its absolute maximum ratings, when the wiring is routed improperly or when an abnormal pulse noise occurs from the wiring or load, causing a large current to continuously flow and the breakdown can lead smoke or ignition. To minimize the effects of the flow of a large current in case of breakdown, appropriate settings, such as fuse capacity, fusing time and insertion circuit location, are required.
IC breakdown may cause injury, smoke or ignition. Use a stable power supply with ICs with built-in protection functions.
If the power supply is unstable, the protection function may not operate, causing IC breakdown. Make sure that the positive and negative terminals of power supplies are connected properly. Otherwise, the current or power consumption may exceed the absolute maximum rating, and exceeding the rating s may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion.
In addition, do not use any device that is applied the current with inserting in the wrong orientation or incorrectly even just one time. If there is a large amount of leakage current such as input or negative feedback condenser, the IC output DC voltage will increase. If this output voltage is connected to a speaker with low input withstand voltage, overcurrent or IC failure can cause smoke or ignition.
The over current can cause smoke or ignition from the IC itself. These ICs generate heat even during normal use. In addition, please design the device taking into considerate the effect of IC heat radiation with peripheral components. To avoid this problem, take the effect of back-EMF into consideration in system design. The information contained herein is subject to change without notice.
Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress.
