DESCRIPTION
The MP2631 is a linear, high performance
single cell Li-Ion or Li-Polymer battery charger
with 10mA LDO and on-chip input polarity
reverse protection. By integrating high voltage
input protection into the charger IC, the
MP2631 can tolerate an input surge up to 28V
and input surge down to -16V.
The MP2631 features constant current (CC)
and constant voltage (CV) charging modes with
programmable charge current (200mA to 1A)
reverse current blocking and trickle charge.
The other features include the internally set
battery full threshold (10% of the programmed
charge current) and auto-recharge.
The OVP circuitry will automatically disconnect
both charger and LDO from input when VIN
exceeds 7V.
