High Input Voltage Single Cell Charger with OVP CE3156 Series „ INTRODUCTION: The CE3156 is a fully integrated high input voltage single-cell Li-Ion battery charger. The charger uses a CC/CV charge profile required by Li-Ion battery. The charger accepts an input voltage up to 26.5V but is disabled when the input voltage exceeds the OVP threshold, typically 10.5V, to prevent excessive power dissipation. The 26.5V rating eliminates the overvoltage protection circuit required in a low input voltage Charger. The charge current and the full-of-charge (FOC) current are programmable with external resistors. When the battery voltage is lower than typically 2.55V(CE3156-4.2), or 2.65V(CE3156-4.35), the charger preconditions the battery with typically 47.5% of the programmed charge current.
