Lithium Ion Battery Protection (for 1-cell in series) MM1491
Lithium Ion Battery Protection (for 1-cell in series)
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 V
CC
and V
IN
pins, but MM1491 has only the V
CC
pin.
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

TERMINAL EXPLANATIONS
Overcurrent detection input pin. Detects discharge current by connection to charging control
FET source pin.
Discharge current = (voltage between V
M
and GND) / (FET 2 ON resistance)
The positive source pin of this IC and connecting the positive terminal of the cell.
Setting the dead time of over-charge detection with the outer capacitor.
This pin drives the gate of the charge control N-ch FET, needs to connect resistor between
source and gate of FET.
Over-charge mode (when charging) : FET OFF
Over-charge mode (when discharging) : FET ON
Over-discharge mode (when discharging) : FET OFF
Over-discharge mode (when charging) : FET ON
Normal mode : FET ON
