Protection for Lithium-Ion/Lithium Polymer Batteries (1 cell)
Monolithic IC MM3099/MM3199 Series April 26, 2004
Outline
This is a protection IC developed for use with 1-serial cell lithium-ion/lithium polymer rechargeable batteries. It
provides a function to protect the batteries by detecting overcharge, overdischarge, discharge overcurrent,
and other abnormalities and turning off the external Nch MOS FET. The outputs of COUT pin (charge FET
control pin) and DOUT pin (discharge FET control pin) are CMOS outputs, so that the external Nch MOS FET
can be driven directly. A charge overcurrent detection function is provided for abnormal charge detection. In
addition, the IC has a built-in timer circuit(for each detection delay time), so that the protection circuitry can
be comprised with fewer external components. Furthermore, by setting the DS pin at VDD level, overcharge,
overdischarge, discharge overcurrent can be detected, and the delay time during release can be shortened.
Features
1. Uses high voltage CMOS process
Absolute maximum rating for charger connection 32V
2. Detection voltage precision
Overcharge detection voltage ±20mV (Ta=25°C),
±25mV (Ta=-5~60°C)
Overdischarge detection voltage ±35mV (Ta=25°C),
±58mV (Ta=-5~60°C)
Discharge overcurrent detection voltage ±10mV (Ta=25°C),
±15mV (Ta=-5~60°C)
3. Built-in detection delay time (timer circuit) Overcharge detection delay time 0.25 ~ 7.0s (mask option)
Overdischarge detection delay time 0.25 ~ 7.0s (mask option)
Discharge overcurrent detection delay time 0.25 ~ 7.0s (mask
option)

4. Includes a charge overcurrent detection function
5. Overcharge, overdischarge, and discharge overcurrent can be detected, and the delay time during release
can be shortened with the DS pin.
6. 0V charging disable function (mask option)
