IP5209
Overview
IP5209 is a fully-integrated multi-function powe.
- Synchronous switching charger and synchronous boost converter 2.1A synchronous switching charger, 2.4A synchronous boost converter boost converter efficiency up to 96% Switching charger efficiency up to 97% Integrated power-path management, charging batteries and charging cellphones at the same time
- Charger Adaptive charging current control, excellent adapter compatibility Charger voltage accuracy ±0.5% Support 4.20V,4.30V and 4.35V batteries Support battery thermal protection (with NTC resistor)
- State of charge (SOC) indicator Integrated 14bit ADC and fuel gauge Integrated LED controller supports 5/4/3 LEDs as the SOC indicator Configurable charging/discharging curve makes the SOC indicate LEDs more even
- Fully featured Integrated flashlight controller Integrated cellphone plug-in and plug-out detector Integrated DCP (Dedicated Charging Port) controller monitors USB data line voltage and automatically provides the correct electrical signatures on the data lines to charge compliant devices
- Low power Smart load detector, switching to standby mode automatically <100 µA standby current
- Ultra simplified BOM Integrated power FET, charging/boosting with a single inductor
- Multiple protections, high reliability Output over-current, over-voltage, short-circuit protection Input over-voltage, over-current, battery over-charge, over-drain, over-current protection Thermal regulation and thermal shutdown, battery NTC protection ESD 4KV, maximum 11V transit over-voltage sustainable
- Fully customizable I2C interface makes customization flexible and low-cost
