The SGM40561 is a low cost battery charger with integrated high input voltage capability for single-cell Li-Ion or Li-polymer batteries. The SGM40561 has a CC/CV charge profile required for Li-Ion battery. The SGM40561 features the over-voltage protection (OVP) function. The OVP threshold is typically 10.5V. The SGM40561 accepts a 26.5V maximum voltage for power input, when VIN > VOVP, the charger is disabled.
The SGM40561 has a charge indication feature. When the charger is disabled or the input is floating, the leakage current from the battery is < 1μA.
The SGM40561 is available in a Green TDFN-2×2-8L package and is rated over the -40℃ to +85℃ temperature range.
