Dear team,

Could you please help suggest the charger solution for the following specification?

1. Vin: 3.5V~8Vmax

2. 3.3V (1 cell) Li-poly charger, 100~200mA

 Thank you.

Best Regards,

    Hello
    The bq24232 may meet the requirement, max OVP is 10.6V. But if the unit does not have to operate at 8V but is OK to turn off at about 6.6V other units are available. Many of the chargers will operate from 3.5V to 6.6V but turn off above that point and survive higher voltages.

    3.3V li-poly charger 100-200mA---typical Li-Polymer battery is about 4.2V charge voltage and 100mA to 200mA can be supported with a linear charger.
