When the voltage applied to the VDD pins reaches the applicable threshold voltage, the VOUT terminal voltage switches from either “High” to “Low” or from “Low” to “High”. Because the BD52xx series uses an open drain output type, it is possible to connect a pull-up resistor to VDD or another power supply [The output “High” voltage (VOUT) in this case becomes VDD or the voltage of the other power supply].

The figures will vary with the application, so please confirm actual operating conditions before use. Timing Waveforms Example: the following shows the relationship between the input voltage VDD, the CT Terminal Voltage VCT and the output voltage VOUT when the input power supply voltage VDD is made to sweep up and sweep down (The circuits are those in Fig.15 and 16). 1 When the power supply is turned on, the output is unsettled from VDD after over the operating limit voltage (VOPL) until tPHL. There fore it is possible that the reset signal is not outputted when the rise time of VDET+ΔVDET ⑤ VDET VDD is faster than tPHL. 2 When VDD is greater than VOPL but less than the reset release VOPL 0V voltage (VDET+∆VDET), the CT terminal (VCT) and output (VOUT) voltages will switch to L. VCT 3 If VDD exceeds the reset release voltage (VDET+∆VDET), then 1/2 VDD VOUT switches from L to H (with a delay to the CT terminal). 4 If VDD drops below the detection voltage (VDET) when the power supply is powered down or when there is a power supply fluctuation, VOUT switches to L (with a delay of tPHL). VOUT tPLH tPHL tPLH 5 The potential difference between the detection voltage and the tPHL release voltage is known as the hysteresis width (∆VDET). The system is designed such that the output does not flip-flop with power ① ② ③ ④ supply fluctuations within this hysteresis width, preventing malfunctions due to noise Fig.17 Timing Waveform www.rohm.com © 2011 ROHM Co., Ltd.

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 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. If 10MΩ leakage is assumed between the CT terminal and the GND terminal, 1MΩ connection between the CT terminal and the VDD terminal would be recommended. The value of RCT depends on the external resistor that is connected to CT terminal, so please consider the delay time that is decided by τ×RCT×CCT changes. 11. External parameters The recommended parameter range for CT is 100pF~0.1µF and 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.
