Hxje Ic Datasheet Top =link= Jun 2026

If you've ever picked up a tiny SOT-23-6 chip in a portable device with the cryptic top marking "HX-JE," you know the frustration of trying to track down its datasheet. The IC is a workhorse of modern portable electronics, and understanding it is the key to efficient, inductor‑free power conversion.

Common ICs often use a 2-4 letter prefix followed by numbers (e.g., LM 358, MAX 232). "HX" is a common prefix for manufacturers like or Nanjing Hi-Lo .

: A description or diagram showing what each pin of the IC is used for. This is crucial for designing and building circuits.

: Check if the datasheet clearly outlines the product's intended applications. Is it suitable for your needs?

The SOT23-6 package for the HX-JE generally follows a standard layout tailored for boost controllers: hxje ic datasheet top

Acts as a small-scale power rail generator to boost 3.7V lithium battery outputs to standard 5V logic lines for MCUs and peripherals.

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

An Integrated Circuit (IC) datasheet is a technical document that acts as a blueprint, detailing the electrical properties and physical requirements needed to integrate the component into a system. For a high-quality IC datasheet, the following content sections are typically included at the top or within the primary pages: Core Technical Content

Low-noise operational profile simplifies electromagnetic interference (EMI) filtering. SOT23-6 / SOT-23-6L If you've ever picked up a tiny SOT-23-6

: Specifically engineered for sensitive circuits that require a "clean" power supply. Protection : Includes thermal shutdown and short-circuit protection. AliExpress Equivalent/Compatible Parts

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.

A mysterious marking like doesn’t mean the datasheet is lost forever. It means you need to stop treating it as a part number and start treating it as a clue .

If non-destructive electrical tests prove inconclusive, physical layer analysis becomes necessary. "HX" is a common prefix for manufacturers like

The core functionality of the HX-JE relies on an . Traditional boost converters require bulky power inductors that consume critical PCB real estate and can radiate high levels of EMI. The HX-JE circumvents this limitation by utilizing internal power MOSFETs to rapidly switch energy between the flying capacitor and the output capacitor. Non-Sensing Feedback Loop

): Positive terminal connection for the external flying charge pump capacitor. Pin 2 ( GNDcap G cap N cap D

integrated circuit typically found in consumer electronics like portable Bluetooth speakers and power banks. It is widely used in Chinese-manufactured electronics as a low-cost solution for generating a regulated 5V rail from a lower lithium-ion battery voltage (3.0V–4.5V). The HX-JE is frequently cross-referenced with the 🛠️ Technical Specifications Based on the datasheet for the Go to product viewer dialog for this item.
