●Description
ROHM standard CMOS reset IC series is a high-accuracy low current consumption reset IC series. The lineup was
established with two output types (Nch open drain and CMOS output) and detection voltage range from 0.9V to 4.8V in
increments of 0.1V, so that the series may be selected according to the application at hand.
●Features
1) Detection voltage from 0.9V to 4.8V in 0.1V increments
2) Highly accurate detection voltage: ±1.0%
3) Ultra-low current consumption
4) Nch open drain output (BU48□□G/F/FVE)and CMOS output (BU49□□G/F/FVE)
5) Small surface package SSOP5: BU48□□G, BU49□□G
SOP4: BU48□□F, BU49□□F
VSOF5: BU48□□FVE, BU49□□FVE
●Applications
All electronics devices that use microcontrollers and logic circuits.

●Explanation of Operation
For both the open drain type(Fig.12)and the CMOS output type(Fig.13), 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 BU48□□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].

●Timing Waveforms
Example:The following shows the relationship between the input voltage VDD, the CT Terminal Voltage VCT 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).
①When the power supply is turned on, the output is unsettled
from after over the operating limit voltage (VOPL) until TPHL.
DD
Therefore it is possible that the reset signal is not outputted
when the rise time of VDD is faster than TPHL.
②When VDD is greater than VOPL but less than the reset release
voltage (VDET + VDET), output (VOUT) voltages will switch to L.
③If VDD exceeds the reset release voltage (VDET + VDET), then
VOUT switches from L to H (with a delay of TPLH).
④If 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).
⑤The potential deference 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.

Application examples of BU48□□G/F/FVE series
(Open Drain output type) and BU49□□G/F/FVE series
(CMOS output type) are shown below.
RL

RST
BU48□□□
CASE1:The power supply of the microcontroller (VDD2) differs
from the power supply of the reset detection (VDD1).
Use the Open Drain Output Type (BU48□□G/FVE)
attached a load resistance (RL) between the output and
VDD2. (As shown Fig.15)
CIN
CL
(Capac itor for
noise filtering)
GND
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 (BU48□□G/FVE) attached a load
resistance (RL) between the output and VDD1.

When a capacitance CL for noise filtering or setting the

into account the waveform of the rise and fall of the
output voltage (Vout).

2)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.) Consider the use of BD48□□when the power
supply input it with resistor dividers.

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 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. Recommended value of RL Resistar is over 10kΩ (VDET=1.5V~4.8V),
over 100kΩ (VDET=0.9~1.4V).
11. 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.
12. External parameters
For Rl, the recommended range is 10kΩ~1MΩ. There are many factors (board layout, etc) that can affect
characteristics. Please verify and confirm using practical applications.
13. Power on reset operation
Please note that the power on reset output varies with the Vcc rise up time. Please verify the actual operation.
14. 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.
15. When the power supply, is turned on because of incertain 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.
