Common Packages

: While "HXJE" is the marking code, similar parts from this manufacturer (HXJ) are often found in SOT23-6 , SOP8 , or SOP16 packages.

Input Voltage Range:

2.7V to 4.5V (optimized for single-cell Li-ion batteries). Regulated Output: Fixed 4.94V ± 3% .

• Check pinout before replacing.

  The BQ24040 uses WSON-10; others may use different packages.

  Typically includes thermal shutdown and short-circuit protection features. SparkFun Electronics Common Equivalents
