xp4302.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 8 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

XP4302

Shenzhen Fuman · Battery Management · ESOP-8

XP4302 from Shenzhen Fuman, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Charger power input. Recommended operating range 4.6V to 5.5V (typ. 5V); VIN UVLO ~4.6V rising / 4.4V falling; VIN OVP ~5.6V; absolute max 8V. Bypass with >=10uF (20uF recommended).
2 LED1 output Charge status indicator 1 (open-drain style LED driver). ON while charging (trickle/CC/CV), OFF when charging is complete. Blinks on OTP or NTC out-of-range fault. May be left floating if unused.
3 LED2 output Charge status indicator 2. OFF while charging, ON when charge is complete (full). May be left floating if unused.
4 VSET input Battery full-charge (regulation) voltage set pin. Default connection: tie to GND for the standard 4.2V full-charge voltage.
5 NTC input Battery temperature sense input. Internal ~70k pull-up to VIN forms a divider with an external 100k NTC (25 degC) in parallel with 300k; charging halts when VNTC > 70%*VIN or < 30%*VIN. Tie to a 75k resistor to GND to disable NTC; must not be left floating.
6 BAT power_out Battery connection / voltage feedback input. Charges single-cell Li-ion to 4.2V (VBAT_FULL), 3.95V recharge threshold, 104%*VBAT OVP. Bypass with >=10uF.
7 SEN input Charge current sense input. Connects to the high side of an external ~5 mOhm sense resistor between the buck inductor/output cap node and BAT for closed-loop current regulation (2A CC).
8 SW output Synchronous buck switch node. Connect to a 10uH inductor to the SEN/output capacitor node. Internal high-side (~60 mOhm) and low-side (~70 mOhm) MOSFETs, 750 kHz fixed switching frequency.
9 GND (Power Pad) power_in Exposed thermal/power ground pad on the bottom of the ESOP-8 package. Must be soldered to the PCB ground plane for proper electrical return and thermal dissipation (RthetaJA ~42 degC/W).
