Figure 1 Reset Circuit of RNA51958  
Notes: 1. When the detecting supply voltage is 4.25 V, RNA51953 are used. In this case, R1 and R2 are not necessary.  
When the voltage is anything except 4.25 V, RNA51957 and RNA51958 are used. In this case, the detecting  
supply voltage is 1.25 (R1 +R2)/R2 (V) approximately.  
The detecting supply voltage can be set between 2 V and 15 V.  
2. If a longer delay time is necessary, RNA51953, RNA51957, RNA51958 are used. In this case, the delay  
time is about 0.34 Cd (pF) s.  
3. If the RNA51958 and the logic circuit share a common power source, type A (built-in load type) can be used  
whether a pull-up resistor is included in the logic circuit or not.  
4. The logic circuit preferably should not have a pull-down resistor, but if one is present, add load resistor RL to  
overcome the pull-down resistor.  
5. When the reset terminal in the logic circuit is of the low reset type, RNA51953 and RNA51957 are used and  
when the terminal is of the high reset type, RNA51958 are used.  
6. When a negative supply voltage is used, the supply voltage side of RNA51958 and the GND side are  
connected to negative supply voltage respectively.

Notice for use  
About the Power Supply Line  
1. About bypass capacitor  
Because the ripple and the spike of the high frequency noise and the low frequency are superimposed to the power  
supply line, it is necessary to remove these.  
Therefore, please install C1 and C2 for the low frequency and for the high frequency between the power supply line  
and the GND line as shown in following figure 5.

2. The sequence of voltage impression  
Please do not impress the voltages to the input terminals earlier than the power supply terminal. Moreover, please  
do not open the power supply terminal with the voltage impressed to the input terminal.  
(The setting of the bias of an internal circuit collapses, and a parasitic element might operate.)  
About the Input Terminal  
1. Setting range of input voltage  
The following voltage is recommended to be input to the input terminal (pin 2).  
about 0.8 (V) < Vin < VCC – 0.3 (V) ... at VCC 7 V  
about 0.8 (V) < Vin < 6.7 (V) ............. at VCC > 7 V  
2. About using input terminal  
Please do an enough verification to the transition characteristic etc. of the power supply when using independent  
power supply to input terminal (pin 2).  
VCC  
Vin is decided to the VCC subordinating,  
and operates in the range  
Power-supply  
about 0.8 (V) < Vin < VCC – 0.3 (V).

3. Calculation of detecting voltage  
Detecting voltage Vs can be calculated by the following expression.  
However, the error margin is caused in the detecting voltage because input current Iin (standard 100 nA) exists if it  
sets too big resistance.  
Please set the constant to disregard this error margin.

Preliminary  
Setting of Delay Capacity  
Please use capacitor Cd for the delay within the range of 10 F or less.  
When a value that is bigger than this is set, the problem such as following (1), (2), and (3) becomes remarkable.  
t
VCC  
Output  
tpd  
tPHL  
Figure 9 Time Chart at Momentary Voltage-Decrease  
(1) The difference at delay time becomes remarkable.  
A long delay setting of tens of seconds is fundamentally possible. However, when set delay time is lengthened, the  
range of the difference relatively grows, too. When a set value is assumed to be ‘tpd’, the difference occurs in the  
range from 0.47 tpd to 2.05 tpd. For instance, 34 seconds can be calculated at 100 F. However, it is likely to  
vary within the ranges of 16-70 seconds.  
(2) Difficulty to react to a momentary voltage decrease.  
For example, the reaction time tPHL is 10 s when delay capacitor Cd = 0.1 F.  
The momentary voltage-decrease that is longer than such tPHL are occurs, the detection becomes possible. When the  
delay capacitance is enlarged, tPHL also becomes long. For instance, it becomes about 100 to 200 s in case of  
circuit constant C1 = 100 F.  
(Characteristic graph 1 is used and extrapolation in case of Cd = 100 F.)  
Therefore, it doesn't react to momentary voltage-decrease that is shorter than this.  
(3) Original delay time is not obtained.  
When the momentary voltage-decrease time ‘t’ is equivalent to tPHL, the discharge becomes insufficient and the  
charge starts at that state. This phenomenon occurs at large capacitance. And, original delay time tpd is not  
obtained.  
Please refer to characteristic graph 2. (Delay time versus input pulse width)

Setting of Output Load Resistance (RNA51958B)  
High level output voltage can be set without depending on the power-supply voltage because the output terminal is an  
open collector type. However, please guard the following notes.  
1. Please set it in value (2 V to 17 V) within the range of the power-supply voltage recommendation.  
Moreover, please never impress the voltage of maximum ratings 18 V or more even momentarily either.  
2. Please set output load resistance (pull-up resistance) RL so that the output current (output inflow current IL) at L  
level may become 4 mA or less. Moreover, please never exceed absolute maximum rating (6 mA).

7. Renesas Electronics products are classified according to the following three quality grades: "Standard", "High Quality", and "Specific". The recommended applications for each Renesas Electronics product  
depends on the product's quality grade, as indicated below. You must check the quality grade of each Renesas Electronics product before using it in a particular application. You may not use any Renesas  
Electronics product for any application categorized as "Specific" without the prior written consent of Renesas Electronics. Further, you may not use any Renesas Electronics product for any application for  
which it is not intended without the prior written consent of Renesas Electronics. Renesas Electronics shall not be in any way liable for any damages or losses incurred by you or third parties arising from the  
use of any Renesas Electronics product for an application categorized as "Specific" or for which the product is not intended where you have failed to obtain the prior written consent of Renesas Electronics.  
The quality grade of each Renesas Electronics product is "Standard" unless otherwise expressly specified in a Renesas Electronics data sheets or data books, etc.  
"Standard":  
Computers; office equipment; communications equipment; test and measurement equipment; audio and visual equipment; home electronic appliances; machine tools;  
personal electronic equipment; and industrial robots.  
"High Quality": Transportation equipment (automobiles, trains, ships, etc.); traffic control systems; anti-disaster systems; anti-crime systems; safety equipment; and medical equipment not specifically  
designed for life support.  
"Specific":  
Aircraft; aerospace equipment; submersible repeaters; nuclear reactor control systems; medical equipment or systems for life support (e.g. artificial life support devices or systems), surgical  
implantations, or healthcare intervention (e.g. excision, etc.), and any other applications or purposes that pose a direct threat to human life.  
8. You should use the Renesas Electronics products described in this document within the range specified by Renesas Electronics, especially with respect to the maximum rating, operating supply voltage  
range, movement power voltage range, heat radiation characteristics, installation and other product characteristics. Renesas Electronics shall have no liability for malfunctions or damages arising out of the  
use of Renesas Electronics products beyond such specified ranges.  
9. Although Renesas Electronics endeavors to improve the quality and reliability of its products, semiconductor products have specific characteristics such as the occurrence of failure at a certain rate and  
malfunctions under certain use conditions. Further, Renesas Electronics products are not subject to radiation resistance design. Please be sure to implement safety measures to guard them against the  
possibility of physical injury, and injury or damage caused by fire in the event of the failure of a Renesas Electronics product, such as safety design for hardware and software including but not limited to  
redundancy, fire control and malfunction prevention, appropriate treatment for aging degradation or any other appropriate measures. Because the evaluation of microcomputer software alone is very difficult,  
please evaluate the safety of the final products or system manufactured by you.  
10. Please contact a Renesas Electronics sales office for details as to environmental matters such as the environmental compatibility of each Renesas Electronics product. Please use Renesas Electronics  
products in compliance with all applicable laws and regulations that regulate the inclusion or use of controlled substances, including without limitation, the EU RoHS Directive. Renesas Electronics assumes
