However, R1 is enlarged, the detection voltage shifts by voltage when ｃurrent consumption flows into R1. Please decide it after confirming the characteristic. Moreover, adjust the value of C1 , C2 to 0.01uF or more to do the stability operation, please. R1 and R3 resistors are current limit resistance if a charger is connected reversibly or a high-voltage charger that exceeds the absolute maximum rating is connected. R1 and R3 may cause a power consumption will be over rating of power dissipation, therefore the `R1+R3` should be more than 1kohm. Moreover, if R3 is too enlarged, the charger connection release cannot be occasionally done after the overdischarge is detected, so adjust the value of R3 to 10kohm or less, please. In the state of overdischarge, The current flows through overdischarge pull-up resistance built into between VDD terminal and V- terminal when the charger is connected. As a result, current that flows into VDD terminal increases. When current increases, the voltage is generated in R1. And hysteresis might be caused. Please use it after confirming the characteristic. C3 and C4 capacitors have effect that the system stability about voltage ripple or imported noise. After check characteristics, decide that these capacitors should be inserted or not, where should be inserted, and capacitance value, please. 4 Lineup tVdet3-1 tVdet3-2 - -0.200V 1.00s 128.0ms 12.0ms SOT26A × ○ 4.250V 4.050V 2.800V 3.000V 0.100V - -0.100V 1.00s 128.0ms SOT26A ○ × 4.300V 4.100V 2.000V 2.000V 0.100V 0.200V - 1.00s 12.0ms C03NRH SOT26A ○ × 4.300V 4.100V 2.000V 2.000V 0.100V 0.200V - 1.00s C08NRH SOT26A ○ × 4.300V 4.100V 2.000V 2.000V 0.065V 0.200V - D01NRH SOT26A × × 4.250V 4.100V 3.000V 3.000V 0.200V - - D05NRH SOT26A × × 4.250V 4.100V 2.500V 2.500V 0.150V - F01NRH SOT26A × 4.225V 4.075V 2.550V 2.550V 0.200V - G01NRH SOT26A × ○ 4.290V 4.050V 3.000V 3.200V 0.200V G06NRH SOT26A × ○ 4.250V 4.100V 2.500V 3.000V 0.150V G07NRH SOT26A H01NRH SOT26A H02NRH※2 H03NRH ※1 SOT26A AA2NRH C02NRH Charging overcurrent detection delay time Discharging overcurrent detection delay time 2 Discharging overcurrent detection delay time 1 tVdet2 × ○ 4.250V 4.050V 2.800V 3.000V 0.200V AA1NRH Vrel2 Vdet3-1 Vdet3-2 Vdet4 tVdet1 Overdischarge detection delay time Overcharge detection delay time Charging overcurrent detection voltage Vdet2 Detection delay time Discharging overcurrent detection voltage 2 Vrel1 Discharging overcurrent detection voltage 1 Overdischarge detection voltage Vdet1 Overdischarge release voltage Overcharge release voltage Detection / Release voltage Overcharge detection voltage Charging overcurrent detection Two stage overcurrent detecting function Product name (MM3220) Package Option tVdet4 - 8.0ms 12.0ms - 8.0ms 48.0ms 4.0ms - 12.0ms 256.0ms 2.5ms - 1.00s 12.0ms 256.0ms 0.5ms - 1.15s 144.0ms 9.0ms - - - 1.15s 144.0ms 9.0ms - - - 1.15s 144.0ms 9.0ms - - - -0.200V 1.00s 128.0ms 12.0ms - 8.0ms - -0.100V 1.00s 12.0ms 256.0ms - 8.0ms × ○ 4.400V 4.250V 2.500V 3.000V 0.150V - -0.100V 1.00s 12.0ms 256.0ms - 8.0ms × ○ 4.225V 4.075V 3.000V 3.000V 0.200V - -0.200V 1.15s 144.0ms 9.0ms - 8.0ms SOT26A × ○ 4.300V 4.150V 2.400V 2.400V 0.200V - -0.200V 1.15s 144.0ms 9.0ms - 8.0ms SOT26A × ○ 4.250V 4.100V 3.200V 3.200V 0.200V - -0.200V 1.15s 144.0ms 9.0ms - 8.0ms H04NRH※2 SOT26A × ○ 4.230V 4.080V 2.400V 2.400V 0.200V - -0.200V 1.15s 144.0ms 9.0ms - 8.0ms H06NRH※2 SOT26A × ○ 4.230V 4.080V 2.865V 2.865V 0.200V - -0.200V 1.15s 144.0ms 9.0ms - 8.0ms H09NRH※2 SOT26A × ○ 4.225V 4.150V 2.600V 2.600V 0.250V - -0.200V 1.15s 1.15s 9.0ms - 8.0ms H10NRH※2 SOT26A × ○ 4.250V 4.175V 2.600V 2.600V 0.250V - -0.200V 1.15s 1.15s 9.0ms - 8.0ms H11NRH SOT26A × ○ 4.300V 4.150V 2.300V 2.300V 0.150V - -0.150V 1.00s 96.0ms 20.0ms - 8.0ms H13NRH SOT26A × ○ 4.250V 4.050V 2.400V 2.400V 0.200V - -0.200V 1.00s 128.0ms 12.0ms - 8.0ms H15NRH※2 SOT26A × ○ 4.280V 4.130V 2.800V 2.800V 0.150V - -0.150V 1.00s 128.0ms 9.0ms - 8.0ms H16NRH SOT26A × ○ 4.250V 4.100V 3.000V 3.000V 0.200V - -0.200V 1.00s 128.0ms 8.0ms - 8.0ms J01NRH※2 SOT26A × ○ 4.275V 4.275V 2.500V 2.500V 0.085V - -0.060V 0.25s 20.0ms 6.0ms - 16.0ms JA1NRH SOT26A × ○ 4.250V 4.250V 2.800V 2.800V 0.100V - -0.100V 1.00s 96.0ms 10.0ms - 6.0ms × K01NRH SOT26A ○ ○ 4.300V 4.100V 2.000V 2.000V 0.125V 0.300V -0.090V 1.15s 144.0ms 12.0ms 0.5ms 8.0ms M01NRH※2 SOT26A × ○ 4.280V 4.080V 2.000V 2.000V 0.200V - -0.100V 1.00s 128.0ms 12.0ms - 8.0ms M04NRH※2 SOT26A × ○ 4.280V 4.080V 2.600V 2.600V 0.135V - -0.085V 1.00s 128.0ms 12.0ms - 8.0ms MB1NRH※2 SOT26A × ○ 4.425V 4.225V 2.800V 2.800V 0.150V - -0.100V 1.00s 128.0ms 8.0ms - 8.0ms MC1NRH※2 SOT26A × ○ 4.300V 4.100V 2.300V 2.300V 0.090V - -0.090V 1.00s 12.0ms 48.0ms - 16.0ms N01NRH SOT26A × × 4.250V 4.100V 2.500V 3.000V 0.150V - - 1.15s 144.0ms 9.0ms - - U01NRH※4 SOT26A × 4.250V 4.100V 2.500V 3.000V 0.150V - - 1.15s 512.0ms 288.0ms - - Z01NRH※3 SOT26A ○ × 4.300V 4.100V 2.000V 2.000V 0.100V 0.180V - 1.00s 12.0ms 256.0ms 2.5ms ※1 Optional functions × ○ ： Provided. × - ： Not provided. ※2 0V Charge Disabled ※3 The charging overcurrent function cannot be added to the Z01 rank. ※4 Overdischarge release method： voltage release 5 NOTES 【Safety Precautions】 ・ Though Mitsumi Electric Co., Ltd.
