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”. Please refer to the Timing Waveform and Electrical Characteristics for information on hysteresis. Because the BD48Exxx-M series uses an open drain output type, it is necessary to connect a pull-up resistor to VDD or another power supply if needed [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 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.12 and 13). 1 VDD VDET+ΔVDET VDET ⑤ VOPL 0V VOUT VOH tPHL tPLH tPLH tPHL VOL ① ② ③ ④ Fig.14 Timing Waveform www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved. TSZ22111・15・001 When the power supply is turned on, the output is unstable from after over the operating limit voltage (VOPL) until tPHL. Therefore it is possible that the reset signal is not valid when the rise time of VDD is faster than tPHL. 2 When V DD is greater than VOPL, but less than the reset release voltage (VDET + ∆VDET), the output voltages will switch to Low. 3 If V DD exceeds the reset release voltage (VDET + ∆VDET), then, VOUT switches from L to H. 4 If V DD 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). 5 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 toggle with power supply fluctuations within this hysteresis width, preventing the malfunctions due to noise. 10/14 TSZ02201-0R7R0G300070-1-2 22.May.2013.Rev.003 Datasheet BD48Exxx-M series BD49Exxx-M series ●Circuit Applications 1) Examples of a common power supply detection reset circuit. VDD2 VDD1 RL BD48Exxx-M RST Micro Controller Application examples of BD48Exxx-M series (Open Drain output type) and BD49Exxx-M series (CMOS output type) are shown on the left. CASE1: Power supply of the microcontroller (VDD2) differs from the power supply of the reset detection (VDD1). Use an open drain output type (BD48xxx-M) device with a load resistance RL attached as shown in figure 15. CL ( Capacitor is for noise filtering ） GND CASE2: Power supply of the microcontroller (VDD1) is same as the power supply of the reset detection (VDD1). Use a CMOS output type (BD49xxx-M) device or an open drain device with a pull up resistor between output and VDD1. Fig.15 Open Drain Output Type VDD1 Micro RST Controller BD49Exxx-M 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).

By pulling-up to VDD3, output “High” voltage of micro-controller power supply is possible. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved.

In-rush current is a sudden surge of current that flows from the power supply (VDD) to ground (GND) as the output logic changes its state. This current flow may cause malfunction in the systems operation such as output oscillations, etc. V1 R2 I1 VDD BD48Exxx-M BD49Exxx-M R1 CIN VOUT CL GND Fig.18 When an in-rush current (I1) flows into the circuit (Refer to Fig. 18) at the time when output switches from “Low” to “High”, a voltage drop of I1×R2 (input resistor) will occur in the circuit causing the VDD supply voltage to decrease. When the VDD voltage drops below the detection voltage, the output will switch from “High” to “Low”. While the output voltage is at “Low” condition, in-rush current will stop flowing and the voltage drop will be reduced. As a result, the output voltage will switches again from “Low” to “High” which causes an in-rush current and a voltage drop. This operation repeats and will result to oscillation.

The damage can either be a short circuit between pins or an open circuit between pins. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. 2) Ground Voltage The voltage of the ground pin must be the lowest voltage of all pins of the IC at all operating conditions. Ensure that no pins are at a voltage below the ground pin at any time, even during transient condition. 3) Recommended operating conditions These conditions represent a range within which the expected characteristics of the IC can be approximately obtained. The electrical characteristics are guaranteed under the conditions of each parameter. 4) Bypass Capacitor for Noise Rejection To help reject noise, put a 1µF capacitor between VDD pin and GND and 1000pF capacitor between VOUT pin and GND. Be careful when using extremely big capacitor as transient response will be affected. 5) Short between pins and mounting errors Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a wrong orientation or if pins are shorted together. Short circuit may be caused by conductive particles caught between the pins. 6) Operation under strong electromagnetic field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. 7) The VDD line impedance might cause oscillation because of the detection current. 8) A VDD to GND capacitor (as close connection as possible) should be used in high VDD line impedance condition. 9) Lower than the mininum input voltage puts condition. the VOUT in high impedance state, and it must be VDD in pull up (VDD) 10) External parameters The recommended parameter range for RL is 10kΩ to 1MΩ. There are many factors (board layout, etc) that can affect characteristics. Please verify and confirm using practical applications. 11) Power on reset operation Please note that the power on reset output varies with the VDD rise time. Please verify the behavior in the actual operation. 12) Testing on application boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. 13) Rush current When power is first supplied to the IC, rush current may flow instantaneously. It is possible that the charge current to the parasitic capacitance of internal photo diode or the internal logic may be unstable. Therefore, give special consideration to power coupling capacitance, power wiring, width of GND wiring, and routing of connections. 14) 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. www.rohm.com © 2013 ROHM Co., Ltd.

The following are examples of safety measures: [a] Installation of protection circuits or other protective devices to improve system safety [b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure 3. Our Products are not designed under any special or extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any special or extraordinary environments or conditions. If you intend to use our Products under any special or extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of product performance, reliability, etc, prior to use, must be necessary: [a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents [b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust [c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2 [d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves [e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items [f] Sealing or coating our Products with resin or other coating materials [g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning residue after soldering [h] Use of the Products in places subject to dew condensation 4. The Products are not subject to radiation-proof design. 5. Please verify and confirm characteristics of the final or mounted products in using the Products. 6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied, confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect product performance and reliability. 7. De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual ambient temperature. 8. Confirm that operation temperature is within the specified range described in the product specification. 9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in this document. Notice - Rev.004 © 2013 ROHM Co., Ltd. All rights reserved. Datasheet Precaution for Mounting / Circuit board design 1. When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product performance and reliability. 2. In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the ROHM representative in advance. For details, please refer to ROHM Mounting specification Precautions Regarding Application Examples and External Circuits 1.

Precaution for Electrostatic This Product is electrostatic sensitive product, which may be damaged due to electrostatic discharge. Please take proper caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be applied to Products. Please take special care under dry condition (e.g. Grounding of human body / equipment / solder iron, isolation from charged objects, setting of Ionizer, friction prevention and temperature / humidity control). Precaution for Storage / Transportation 1. Product performance and soldered connections may deteriorate if the Products are stored in the places where: [a] the Products are exposed to sea winds or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2 [b] the temperature or humidity exceeds those recommended by ROHM [c] the Products are exposed to direct sunshine or condensation [d] the Products are exposed to high Electrostatic 2. Even under ROHM recommended storage condition, solderability of products out of recommended storage time period may be degraded. It is strongly recommended to confirm solderability before using Products of which storage time is exceeding the recommended storage time period. 3. Store / transport cartons in the correct direction, which is indicated on a carton with a symbol. Otherwise bent leads may occur due to excessive stress applied when dropping of a carton. 4. Use Products within the specified time after opening a humidity barrier bag. Baking is required before using Products of which storage time is exceeding the recommended storage time period.
