M51955A,B/M51956A,B REJ03D0777-0200 Rev.2.00 Aug 20, 2007 Page 6 of 11 Example of Application Circuit Reset Circuit of M5195xx Series RL VCC M51955x M51956x RESET (RESET) Logic circuit GND GND OutputInput Power- supply Power- supply Figure 1 Reset Circuit of M5195xx Series Notes: 1. When the detecting supply voltage is 4.25 V, M51951, M51952, M51953 and M51954 are used. In this case, R1 and R2 are not necessary. When the voltage is anything except 4.25 V, M51955, M51956, M51957 and M51958 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, M51951, M51952, M51955 and M51956 are available. These ICs have a delay capacity and the delay time is about 200 µs. If a longer delay time is necessary, M51953, M51954, M51957 and M51958 are used. In this case, the delay time is about 0.34 × Cd (pF) µs. 3. If the M5195xx and the logic circuit share a common pow er 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 R L to overcome the pull-down resistor. 5. When the reset terminal in the logic circuit is of the low reset type, M51951, M51953, M51955 and M51957 are used and when the terminal is of the high reset type, M51952, M51954, M51956 and M51958 are used. 6. When a negative supply voltage is used, the supply voltage side of M5195xx and the GND side are connected to negative supply voltage respectively.

M51955A,B/M51956A,B REJ03D0777-0200 Rev.2.00 Aug 20, 2007 Page 9 of 11 Setting of Output Load Resistance (M51955B/M51956B) 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) R L 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 (2V to 17V) IL ≤ 4mA RL Figure 6 Output Load Resistance RL Others 1.
