Voltage Detector IC Series
Counter Timer Built-in
CMOS Voltage Detector IC
No.09006ECT06
BD45□□□G, BD46□□□G series
 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

 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].

when the input power supply voltage VDD is made to sweep up and sweep down (the circuits are those in Fig. 12 and 13).

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 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.

Application examples of BD45□□□G series (Open Drain

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)

When there are many power supplies of the system, power supplies VDD1 and VDD2 are being monitored separately, and
it is necessary to reset the microcomputer, it is possible to use an OR connection on the open drain output type BD45□□□G
series to pull-up to the desired voltage (VDD3) as shown in Fig. 20 and make the output “High” voltage matches the power
supply voltage VDD3 of the microcontroller.

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.)

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.

Technical Note
BD45□□□G, BD46□□□G series
 Operation 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 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.
