The SGM4056 is a low cost battery charger with integrated high input voltage capability for single-cell Li-Ion or Li-polymer batteries. The SGM4056 has a CC/CV charge profile required for Li-Ion battery. The SGM4056 features the over-voltage protection (OVP) function. The OVP threshold is typically 6.8V (SGM4056-6.8) or 10.5V (SGM4056-10.5). The SGM4056 accepts a 26.5V maximum voltage for power input, when VIN > VOVP, the charger is disabled.
The SGM4056 has a charge indication feature. When the charger is disabled or the input is floating, the leakage current from the battery is < 1μA.
The SGM4056 is available in Green TDFN-3×3-8L, TDFN-2×3-8L, TDFN-2×2-8L and SOIC-8 (Exposed Pad) packages and is rated over the -40℃ to +85℃ temperature range.
