MM1491 Protection of Lithium Ion Battery

PIN No. PIN Name TERMINAL EXPLANATIONS Overcurrent detection input pin. Detects discharge current by connection to charging control 1 VM FET source pin. Discharge current = (voltage between VM and GND) / (FET 2 ON resistance) 2 VCC The positive source pin of this IC and connecting the positi.
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 .
