Hxje Ic Datasheet Top May 2026

A mysterious marking like HXJE 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.

Use SMD code databases, examine the PCB’s function, and think like the engineer who chose that chip. Most of the time, you’ll uncover the real part – and a usable datasheet – in under 15 minutes.

The HXJE (often marked as HX-JE or HX=JE) is a high-efficiency DC-DC step-up (boost) converter integrated circuit typically found in a SOT-23-6 package. It is widely used in small portable electronics to provide stable voltage to components from lower-voltage sources like single-cell batteries. Technical Specifications

This IC is frequently identified in industry listings and community forums as an equivalent or specific marking for the HX4004 series or the PS3120A. Function: Non-sensing boost converter. Package: SOT-23-6 (Small Outline Transistor with 6 pins). hxje ic datasheet top

Input Voltage Range: Typically 2.7V to 4.5V (optimized for Li-ion or NiMH batteries).

Application: Ideal for LED drivers, small handheld devices, and battery-powered sensors where space is limited. Pin Configuration

While specific datasheet diagrams can be difficult to source directly, the typical SOT-23-6 boost converter layout for this family (like the HX4004) includes: Vout: Output voltage pin. GND: Ground.

FB/VSET: Feedback or voltage setting pin to regulate output. SHDN/EN: Shutdown or enable pin (active high). Vin: Input supply voltage. LX/SW: Switching pin connected to the external inductor. Common Substitutes and Cross-References A mysterious marking like HXJE doesn’t mean the

If you are unable to find the original HXJE branded part, engineers often use cross-referenced components with similar electrical characteristics:

HX4004 / HX4004A: Often cited as the direct manufacturer part number for the HXJE marking.

PS3120A: A common alternative listed by component suppliers.

LTC4054: While a different function (charger), it is sometimes mentioned in similar circuit repair contexts for portable audio devices. Usage Notes At C/10 termination, STAT1/STAT2 toggle to indicate "charge

External Components: To function correctly, this IC requires a small set of external components, including an inductor (typically 2.2µH to 10µH), Schottky diode (if not internal), and input/output capacitors.

Procurement: You can often find these through specialized distributors like Jotrin Electronics or IC Best. HX-JE - Discrete Semiconductors - Jotrin Electronics

The Texas Instruments BQ24040 is a highly integrated linear charger for single-cell Li-Ion and Li-Poly batteries. It is widely used in portable devices due to its small size, thermal regulation, and absence of external sense resistors.

We’ve all been there. You’re reverse-engineering a board, sorting through a loose parts bin, or examining a blown IC, and you see a marking like HXJE. You search “HXJE IC datasheet top”… and hit a wall.

No results. No forum threads. Just confusion.

So what is the HXJE, and more importantly, how do you find its top-tier datasheet? Let’s dig in.
