Hxje Ic Datasheet Top

The "top" features of the HXJE datasheet usually center on its robustness and simplicity. While specific voltage ratings can vary by suffix (e.g., HXJE-3A, HXJE-S), the core specifications typically include:

Position low-ESR ceramic capacitors (typically ) as close as possible to Pin 6 ( VINcap V sub cap I cap N end-sub ) and Pin 4 ( VOUTcap V sub cap O cap U cap T end-sub ) relative to the ground pin. Grounding Plane: Ensure the GNDcap G cap N cap D

Tailored for applications requiring voltage stepping without complex external sensing components.

The is a high-performance, dual-channel bridge-tied load (BTL) audio power amplifier IC capable of delivering 3.5W of continuous output power per channel into a 4Ω load when powered by a 5V supply. Its robust feature set makes it an ideal choice for a wide range of audio applications where efficiency, sound quality, and low power consumption are critical.

Key features (what to scan first)

The (primarily known by its full manufacturer part numbers HX4004 or HX4004A ) is a highly sought-after, low-noise, regulated charge pump DC-DC boost converter. Manufactured by Hexin Semiconductor, this component is widely recognized in engineering and electronics repair circles by its top-side SMD marking code: HX=JE (or HX-JE). Packaged in a compact SOT-23-6 format , it is an inductorless voltage doubler and step-up chip designed to deliver a fixed 5V output from low-voltage inputs, typically sourced from lithium-ion batteries. SHDN/EN: Shutdown or enable pin (active high)

The marking "HXJE" typically follows a specific vendor logic:

The (often marked as "HX=JE") is a specialized Non-Sensing Boost Integrated Circuit (IC) typically manufactured by HEXIN . It is designed to provide stable voltage boosting for electronic systems without requiring external sensing components, which simplifies circuit design and improves space efficiency. Core Specifications Manufacturer: HEXIN Package Type: SOT23-6 (compact 6-pin surface mount) Function: Non-sensing step-up (boost) converter Status: Lead-free / RoHS Compliant Pin Configuration (SOT23-6)
