Overview

MITSUMI Protection of Lithium Ion Battery (one cell) MM1491 Protection of Lithium Ion Battery (one cell) 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±0.025 Overcharge detection voltage temperature conditions C C C C C C C C C C Overcharge detection hysteresis voltage (V) 200±100 200±100 200±100 200±100 200±100 150±100 150±100 200±100 150±100 200±100 Overdischarge Overdischarge Overcurrent detection resumption detection voltage (V) voltage (V) voltage (mV) 2.3±0.1 2.4±0.1 2.3±0.1 2.3±0.1 2.3±0.1 2.4±0.1 2.4±0.1 2.5±0.1 2.4±0.1 2.5±0.1 3.00±0.12 3.00±0.12 2.90±0.12 3.90±0.12 3.00±0.12 3.00±0.12 3.00±0.12 3.00±0.12 3.00±0.12 3.00±0.12 200±26 200±26 120±16 200±26 200±26 150±20 150±20 200±26 150±20 200±26 u The series will continue to be expanded.
