Fujitsu MB3845, MB3842 Usage Precaution, Ordering Information, Do not apply negative voltages

MB3842/MB3845

■USAGE PRECAUTION

1.Never use settings exceeding maximum rated conditions.

Exceeding maximum rated conditions may cause permanent damage to the LSI.

Also, it is recommended that recommended operating conditions be observed in normal use. Exceeding recommended operating conditions may adversely affect LSI reliability.

2.Use this device within recommended operating conditions.

Recommended operating conditions are values within which normal LSI operation is warranted.

Standard electrical characteristics are warranted within the range of recommended operating conditions and within the listed conditions for each parameter.

3.Printed circuit board ground lines should be set up with consideration for common impedance.

4.Take appropriate static electricity measures.

•Containers for semiconductor materials should have anti-static protection or be made of conductive material.

•After mounting, printed circuit boards should be stored and shipped in conductive bags or containers.

•Work platforms, tools, and instruments should be properly grounded.

•Working personnel should be grounded with resistance of 250 kΩ to 1 MΩ between body and ground.

5.Do not apply negative voltages.

The use of negative voltages below –0.3 V may create parasitic transistors on LSI lines, which can cause abnormal operation.

6.Reverse Current Prevention Function

Current cannot flow back to the VIN pin with the switch off, even when the OUT pin voltage is higher than the VIN pin (OUT ≥ VIN), however when VIN pin voltage is lower than 1.5 V circuit functions are lost, so that in this

case there is danger of reverse current flow. For applications in which reverse flow is not acceptable, set VIN ≥ 1.5 V.
