When the voltage is anything except 4.25 V, RNA51955, 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. When the delay time is short, RNA51951 and RNA51955 are available. These ICs have a delay capacity and the delay time is about 200 s. If a longer delay time is necessary, RNA51953, RNA51957, and RNA51958 are used. 3. If the RNA5195xx 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, RNA51951, RNA51953, RNA51955, 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 RNA5195xx and the GND side are connected to negative supply voltage respectively.

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 2. VCC + C1 C2 Power-supply Output RNA51951 GND Example of ripple noise measures Figure 2 Example of Ripple Noise Measures Setting of Output Load Resistance (RNA51951B) 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). VCC (2 V to 17 V) RL 6 IL ≤ 4 mA Figure 3 Output Load Resistance RL Others 1.
