Voltage Detector IC Series Counter Timer Built-in CMOS Voltage Detector IC BD45□□□G, BD46□□□G series No.09006ECT06  Description ROHM’s BD45□□□G and BD46□□□G series are highly accurate, low current consumption reset IC series. Because the counter timer delay circuit is built into those series, an external capacitor for the delay time setting is unnecessary. The lineup was established with tow output types (Nch open drain and CMOS output) and detection voltages range from 2.3V to 4.8V in increments of 0.1V, so that the series may be selected according the application at hand.  Features 1) Detection voltage: 2.3V to 4.8V (Typ.), 0.1V steps 2) High accuracy detection voltage:±1.0% 3) Ultra-low current consumption: 0.85µA (Typ.) 4) Operating temperature range: -40°C to +105°C 6) SSOP5 compact surface mount packages 5) Three internal, fixed delay time: 50ms, 100ms and 200ms 7) Nch open drain output (BD45□□□G), CMOS output (BD46□□□G)  Applications All electronic devices that use microcontrollers and logic circuits  Selection Guide No. 1 Specifications Output Circuit Format Detection Voltage Fixed Delay Times Description 5:Open Drain Output, 6:CMOS Output Example: Displays VDET over a 2.3V to 4.8V range in 0.1V increments.

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”. Because the BD45□□□G 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 possible that the reset signal is not outputted when the rise time of VDD is faster than TPHL. 2 When VDD is greater than VOPL but less than the reset release voltage (VDET + ∆VDET), the output voltages will switch to Low. 3 If VDD exceeds the reset release voltage (VDET + ∆VDET), the counter timer start and VOUT switches from L to H. 4 When more than the high level voltage is supplied ER terminal, VOUT comes to “L” after tPLH delay time. Therefore, a time when ER terminal is “H” is necessary for 100µsec or more. 5 When the ER terminal switches to Low, the counter timer starts to operate, a delay of tPLH occurs, and VOUT switches from “L” to “H”. 6 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). 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. www.rohm.com © 2009 ROHM Co., Ltd.

Technical Note VDD1 RL BD45□□□ Microcontroller VDD2 Application examples of BD45□□□G series (Open Drain output type) and BD46□□□G series (CMOS output type) are shown below. CASE1: the power supply of the microcontroller (VDD2) differs from the power supply of the reset detection (VDD1). Use the open drain output type (BD45□□□G) 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 (BD46□□□G) or open drain output type (BD45□□□G) attached a load resistance (RL) between the output and Vdd1. (As shown Fig.19) CL (Noise-filtering Capacitor) GND Fig.18 Open Collector Output Type VDD1 BD46□□□ Microcontroller CL (Noise-filtering Capacitor) 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).

All rights reserved. 6/9 2009.05 - Rev.C BD45□□□G, BD46□□□G series Technical Note Examples of the power supply with resistor dividers In applications where the power supply input terminal (VDD) of an IC with resistor dividers, it is possible that a through current will momentarily flow into the circuit when the output logic switches, resulting in malfunctions (such as output oscillatory state). (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 R2 I1 VDD R1 CIN ER BD45□□□G BD46□□□G CL GND VOUT Fig.21 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.

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. www.rohm.com © 2009 ROHM Co., Ltd.
