ell) Monolithic IC MM1491 Outline This IC is a smaller, higher precision type of lithium ion battery protection IC as compared to the MM1301 series, and precision of ±25mV is guaranteed at 0°C ~ 50°C. MM1301 had both VCC and VIN pins, but MM1491 has only the VCC pin. 1-Cell Protection ICs Temperature conditions A:Ta=-25 ~ 75°C, B:Ta=-20 ~ 70°C, C:Ta=0 ~ 50°C, D:Ta=0 ~ 40°C, E:Ta=-20 ~ 25°C Package Model SOT-26A ts AN BN c GN u HN d JN MM1491 o MN r SN WN P YN t ZN Overcharge detection voltage (V) 4.200±0.025 4.350±0.025 4.280±0.025 4.200±0.025 4.250±0.025 4.250±0.025 4.295±0.025 4.325±0.025 4.300±0.025 4.325±0.
