FP8208AXR-G1

Advanced Analog Technology · Battery Management · SOP-8-EP

FP8208AXR-G1 from Advanced Analog Technology, in a SOP-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in Supply voltage input, recommended 4.8V to 5.5V, with the charger held in shutdown until VCC rises above the 4.5V UVLO threshold.
2 EN input Enable control input where a logic level below 0.5V puts the charger into shutdown and a level above 2.5V is required for enable.
3 CHRGB output Charge state indicator 1 output, which is pulled low during charging with VCHRGB at most 0.6V at 5mA sink.
4 STDBY output Charge state indicator 2 output, which is pulled low at charge termination with VSTDBY at most 0.6V at 5mA sink.
5 TEMP input Battery temperature detector input that stops charging when the voltage is above 80% or below 45% of VCC, and must be shorted to GND if battery temperature monitoring is not used.
6 VBAT power_out Battery voltage connection where the charger regulates the float voltage to 4.2V with ±1% accuracy and the battery current is limited to 4.5A absolute maximum.
7 VS power_in Charge current-sense input connected across the sense resistor RS to the BAT pin, which sets charge current against an internal 50mV reference.
8 LX input Switch node and inductor connection pin, with LX voltage rated from -0.3V to 7V and LX to VCC rated at -7V.
9 EP power_in Exposed pad that must be connected to ground.
