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 BD45xx 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 Waveform Example: the following shows the relationship between the input voltages VDD, the output voltage VOUT and ER terminal when the input power supply voltage VDD is made to sweep up and sweep down (the circuits are those in Fig. 12 and 13). 1 When the power supply is turned on, the output is unsettled from 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 VDD of VDD is faster than tPHL. VOPL 2 When V 0V DD is greater than VOPL but less than the reset release voltage (VDET + VDET), the output voltages will switch to Low. VOH 3 If V tPLH tPLH DD exceeds the reset release voltage (VDET + VDET), the tPLH VOUT counter timer start and VOUT switches from L to H. tPHL VOL 4 When more than the high level voltage is supplied ER terminal, tPHL VOUT comes to "L" after tPLH delay time. Therefore, a time when ER VEH terminal is "H" is necessary for 100sec or more. ER 5 When the ER terminal switches to Low, the counter timer starts to tPHL operate, a delay of tPLH occurs, and VOUT switches from "L" to "H". 6 If V DD drops below the detection voltage (VDET) when the power supply is powered down or when there is a power supply Fig.17 Timing Waveform fluctuation, VOUT switches to L (with a delay of tPHL). 7 The potential difference between the detection voltage and the release voltage is known as the hysteresis width (VDET). The system is designed such that the output does not flip-flop with power supply fluctuations within this hysteresis width, preventing malfunctions due to noise. These time changes by the application and use it, please verify and confirm using practical applications. VDD VDET+VDET VDET www.rohm.com (c) 2011 ROHM Co., Ltd. All rights reserved.

TSZ2211115001 9/10 TSZ02201-0R7R0G300010-1-2 19.DEC.2011 Rev.002 BD45xxx series Datasheet BD46xxx series Operational 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 1F 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 1M is assumed between the ER terminal and the GND terminal, 100k 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 50k to 1M. 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.
