Issue 3: Marking "HXJE" but no output

Cause: Might be a different IC if on a Chinese module (e.g., TP4057 clone).
Fix: Measure pin 9 (OUT) with battery disconnected. Should be 4.2V. If 0V, test IN voltage. If still 0V, IC is dead.

While specific pin counts can vary (commonly SOP-8 or DIP-8 packages), the standard pin configuration for a standard HXJE driver IC is as follows:

VCC (Supply Voltage): Powers the internal control logic. The datasheet typically specifies a startup current in the microampere range to ensure quick initialization.
GND (Ground): Common ground reference for the IC.
DRV (Gate Drive): Output pin to drive the external or internal MOSFET gate (if not fully integrated).
FB (Feedback): Receives the feedback signal from the output to regulate voltage or current.
CS (Current Sense): Senses the current through the source of the MOSFET for cycle-by-cycle current limiting.

2. hxje Specifics

Without a specific datasheet reference for "hxje," it's difficult to provide targeted information. It's possible that:

hxje could refer to a part number or a code specific to a certain manufacturer or a particular component.
If hxje is a part number, looking up its datasheet directly through a manufacturer's website or database (like Digi-Key, Mouser, or directly through the IC manufacturer's site) would provide precise information.

Issue 1: IC heats up excessively

Cause: Input voltage too high (>6.4V) or charge current too high for thermal dissipation.
Fix: Reduce input to 5.0V exactly, or lower I_CHG using larger R_ISET.
