| Description | The LP3945 and LP3946 are complete charge management systems that safely charge and maintain a Li-Ion battery or a four-cell Ni-MH (LP3945 only) battery pack. The LP3945 offers the flexibility of prog... |
| Features |
Ni-MH charging mode as well. The charger has under-voltage and over-voltage protection as well as an internal 5.6 hr timer to prevent overcharging the battery. There are two open drain outputs for status indication. An internal amplifier readily converts the charge current into a voltage. Also, the charger can operate in an LDO mode providing up to 1 Amp to the load.
Features
n Integrated pass transistor n Does not require external charge current setting or sensing resistors n I2C interface (LP3945 only) — programmable charge current, EOC current and battery regulation voltage n Near-depleted... |
