Hxje Ic Datasheet Top

(often marked as ) is a high-efficiency, DC-DC charge pump boost converter

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.

(the common equivalents), the device is a switched-capacitor voltage doubler. Input Voltage Range: 2.7V to 4.5V. Fixed Output Voltage: 5.0V (typically regulated at 4.94V ± 3%). Output Current: Operating Frequency: 360kHz (low noise constant frequency). Package Type: Go to product viewer dialog for this item. (6-pin surface mount). Efficiency:

High efficiency without the need for an external inductor (uses a "flying capacitor"). 📍 Pin Configuration (SOT-23-6)

Since this is a charge pump IC, its pinout is standard for the 4004/3120 series: Description Regulated Output Voltage (5V) Flying Capacitor Negative Terminal Flying Capacitor Positive Terminal Input Voltage (Battery) Active High Enable Pin 💡 Key Features and Applications No Inductor Needed:

Uses small ceramic capacitors to boost voltage, saving board space. Low Noise: hxje ic datasheet top

The fixed frequency operation minimizes electromagnetic interference (EMI), crucial for audio applications. Applications: Regulating power for Bluetooth speaker control boards. White LED backlighting. Battery-powered medical instruments. Li-Ion to 5V local conversion. 🔍 Identification Tips

Look for "HX=JE" or "HX-JE" on the top of the SOT-23-6 package.

Often carries the "HX" manufacturer mark, which corresponds to various specialized Chinese semiconductor houses. Go to product viewer dialog for this item. HX-JE - Discrete Semiconductors - Jotrin

3. Absolute Maximum Ratings

Designing within the absolute maximum ratings is critical to preventing catastrophic failure. Standard ratings for the HXJE family typically include:

| Parameter | Symbol | Range | Unit | | :--- | :---: | :--- | :---: | | Supply Voltage | $V_CC$ | -0.3 to 30 | V | | Input Voltage Range | $V_IN$ | 0 to 600+ | V | | Operating Temperature | $T_opr$ | -40 to +85 | °C | | Junction Temperature | $T_j$ | +150 | °C | (often marked as ) is a high-efficiency, DC-DC

Issue 1: IC heats up excessively

• Cause: Input voltage too high (>6.4V) or charge current too high for thermal dissipation.
• Fix: Reduce input to 5.0V exactly, or lower I_CHG using larger R_ISET.

Approach to Reviewing a Datasheet or Product

When reviewing a datasheet or a product like the one implied by "hxje ic datasheet top", consider the following aspects:

1. Specifications and Features: Look at the technical specifications provided. Are they clear and comprehensive? Do they meet your requirements for the intended application?

2. Quality and Reliability: Is there information on the product's reliability, MTBF (Mean Time Between Failures), or any quality certifications (e.g., ISO standards)?

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

4. Electrical Characteristics: For an IC, this would include parameters like voltage ratings, current ratings, and timing characteristics. Are these adequately specified? Cause : Input voltage too high (>6

5. Packaging and Physical Characteristics: Are the product's physical dimensions, pinout, and packaging type well-documented?

6. Comparisons: If possible, compare the product with similar ICs from competitors. How does it stack up in terms of performance, price, and features?

7. Documentation and Support: Look for additional resources provided by the manufacturer, such as application notes, evaluation boards, or technical support contacts.

8. Manufacturer Reputation: Consider the reputation of the manufacturer. Are they known for producing high-quality, reliable components?

Issue 2: Battery does not charge, STAT1/STAT2 both off

• Cause: EN pin pulled high, or input undervoltage lockout (UVLO).
• Fix: Pull EN to GND via 10k resistor. Check V_IN > 4.35V.

2. hxje Specifics

Without a specific datasheet reference for "hxje," it's difficult to provide targeted information. It's possible that:

• hxje could refer to a part number or a code specific to a certain manufacturer or a particular component.
• If hxje is a part number, looking up its datasheet directly through a manufacturer's website or database (like Digi-Key, Mouser, or directly through the IC manufacturer's site) would provide precise information.
