The figures will vary with the application, so please confirm actual operating conditions before use. ●Explanation of Operation For both the open drain type(Fig.15)and the CMOS output type(Fig.16), the detection and release voltages are used as threshold voltages. 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”. BU42□□G/F/FVE and BU43□□G/F/FVE have delay time function which set TPLH (Output “Low””High”) using an external capacitor (CCT). Because the BU42□□G/F/FVE 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].

There fore it is VDET+ΔVDET possible that the reset signal is not outputted when the rise time of ⑤ VDET VDD is faster than TPHL. VDD VOPL ② When VDD is greater than VOPL but less than the reset release 0V voltage (VDET+∆VDET), the CT terminal (VCT) and output (VOUT) voltages will switch to L. 1/2 VDD ③ If VDD exceeds the reset release voltage (VDET+VDET), then VOUT VCT 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, TPLH TPHL TPLH VOUT switches to L (with a delay of TPHL). TPHL VOUT ⑤ The potential difference between the detection voltage and the release voltage is known as the hysteresis width (VDET). The system ①② ③④ is designed such that the output does not flip-flop with power supply Fig.17 fluctuations within this hysteresis width, preventing malfunctions due to noise. www.rohm.com © 2009 ROHM Co., Ltd.

CASE1:The power supply of the microcontroller (Vdd2) differs from the power supply of the reset detection (Vdd1). Use the Open Drain Output Type (BU42□□G/FVE) attached a load resistance (RL) between the output and Vdd2. (As shown Fig.18) CASE2:The power supply of the microcontroller (Vdd1) is same as the power supply of the reset detection (Vdd1). Use CMOS output type (BU43□□G/FVE) or Open Drain Output Type (BU42□□G/FVE) attached a load resistance (RL) between the output and Vdd1. (As shown Fig.19) When a capacitance CL for noise filtering is connected to the Vout pin (the reset signal input terminal of the microcontroller), please take into account the waveform of the rise and fall of the output voltage (Vout).

(Through-current is a current that momentarily flows from the power supply (VDD) to ground (GND) when the output level switches from “High” to “Low” or vice versa.) V1 IDD R2 I1 VDD Through Current R1 CIN BU42□□ BU43□□ CL GND VOUT 0 Fig.20 VDET VDD A voltage drop of [the through-current (I1)] × [input resistor (R2)] is caused by the through current, and the input voltage to descends, when the output switches from “Low” to “High”. When the input voltage decreases and falls below the detection voltage, the output voltage switches from “High” to “Low”. At this time, the through-current stops flowing through output “Low”, and the voltage drop is eliminated. As a result, the output switches from “Low” to “High”, which again causes the through current to flow and the voltage drop. This process is repeated, resulting in oscillation. Consider the use of BU42□□ when the power supply input it with resistor dividers.

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 that 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 to reject noise between VDD pin and GND with 1uF over and between VOUT pin and GND with 1000pF. 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 is 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. Case of needless Delay time, recommended to insert more 470kΩ resister between VDD and CT. Recommended value of RL Resistar is over 50kΩ (VDET=1.5~4.8V),over 100kΩ (VDET=0.9~1.4V). 12. 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 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. Also, 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. 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. www.rohm.com © 2009 ROHM Co., Ltd.

External parameters The recommended parameter range for CT is 100pF~0.1µF. For RL, the recommended range is 50kΩ~1MΩ. There are many factors (board layout, etc) that can affect characteristics. Please verify and confirm using practical applications. 15. CT pin discharge Due to the capabilities of the CT pin discharge transistor, the CT pin may not completely discharge when a short input pulse is applied, and in this case the delay time may not be controlled. Please verify the actual operation. 16. Power on reset operation Please note that the power on reset output varies with the Vcc rise up time. Please verify the actual operation. 17. 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. 18. 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. www.rohm.com © 2009 ROHM Co., Ltd.
