Operation Notes
1 . Absolute maximum range
Absolute Maximum Ratings are those values beyond which the life of a device may be destroyed. We cannot be defined the failure mode,
such as short mode or open mode. Therefore a physical security countermeasure, like fuse, is to be given when a specific mode to be
beyond absolute maximum ratings is considered.
2 . GND potential
GND terminal should be a lowest voltage potential every state.
Please make sure all pins, which are over ground even if, include transient feature.
3 . Electrical Characteristics
Be sure to check the electrical characteristics that are one the tentative specification will be changed by temperature, supply voltage, and
external circuit.
4 . Bypass Capacitor for Noise Rejection
Please put into the capacitor of 1μF or more between VDD pin and GND, and the capacitor of about 1000pF between VOUT pin and GND, to
reject noise. If extremely big capacitor is used, transient response might be late. Please confirm sufficiently for the point.
5 . Short Circuit between Terminal and Soldering
Don’t short-circuit between Output pin and VDD pin, Output pin and GND pin, or VDD pin and GND pin. When soldering the IC on circuit
board, please be unusually cautious about the orientation and the position of the IC. When the orientation is mistaken the IC may be
destroyed.
6 . Electromagnetic Field
Mal-function may happen when the device is used in the strong electromagnetic field.
7 .
The VDD line inpedance might cause oscillation because of the detection current.
8 .
A VDD -GND capacitor (as close connection as possible) should be used in high VDD line impedance condition.
9 .
Lower than the mininum input voltage makes the VOUT high impedance, and it must be VDD in pull up (VDD) condition.
10. This IC has extremely high impedance terminals. Small leak current due to the uncleanness of PCB surface might cause unexpected
operations. Application values in these conditions should be selected carefully. If the leakage of about 1MΩ is assumed between the ER
terminal and the GND terminal, 100kΩ connection between the ER terminal and the VDD terminal would be recommended. If the leakage
is assumed between the VOUT terminal and the GND terminal, the pull-up resistor should be less than 1/10 of the assumed leak resistance.
11. External parameters
The recommended parameter range for RL is 50kΩ～1MΩ. There are many factors (board layout, etc) that can affect characteristics.
Please verify and confirm using practical applications.
12. Power on reset operation
Please note that the power on reset output varies with the VDD rise up time. Please verify the actual operation.
13. Precautions for board inspection
Connecting low-impedance capacitors to run inspections with the board may produce stress on the IC. Therefore, be certain to use proper
discharge procedure before each process of the test operation.
To prevent electrostatic accumulation and discharge in the assembly process, thoroughly ground yourself and any equipment that could
sustain ESD damage, and continue observing ESD-prevention procedures in all handing, transfer and storage operations. Before
attempting to connect components to the test setup, make certain that the power supply is OFF. Likewise, be sure the power supply is OFF
before removing any component connected to the test setup.
14. When the power supply, is turned on because of in certain cases, momentary Rash-current flow into the IC at the logic unsettled, the couple
capacitance, GND pattern of width and leading line must be considered.
