Since "HXJE" is just the marking, you need the . Here are the top reliable sources:
The marking code represents the HX4004A (specifically the HX4004A-MF or HX4004A-MFC variant), a high-efficiency, low-noise, regulated charge pump DC-DC step-up converter . Alternatively, the identical "HX=JE" surface marking is shared by the PS3120A voltage doubler, functioning as a pin-to-pin compatible replacement. This specialized component uses an inductorless "non-sensing" design inside a compact SOT23-6 package to boost low lithium-ion battery voltages up to a stable 5V output. Core Specifications Overview
