The absolute maximum input voltage is 26.5V.

A 1μF or larger value X5R ceramic capacitor is recommended to be placed very close to the input pin for decoupling purpose.

Additional capacitance may be required to provide a s

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 inp
