Hxje Ic Datasheet Top May 2026

The HX-JE (often marked as HX=JE) is a high-efficiency integrated circuit primarily used as a DC-DC boost converter or regulated charge pump voltage doubler. It is widely recognized for its compact SOT23-6 package and its ability to provide a stable 5V output from low-voltage sources like lithium-ion batteries. Core Specifications of the HX-JE IC

Beyond semiconductors, "HXJE" appears as an engine code for certain 1.25L Duratec engines (often found in Ford vehicles like the Fiesta). In this context, it refers to specific automotive timing tools and engine components rather than an electronic chip. HX-JE HX4004 HX4004-MFC SOT23 IC Nguồn DC-DC hxje ic datasheet top

• 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.

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

• High Input Voltage Range: The IC is designed to connect directly to rectified mains voltage. It typically supports input voltages from 90V to 300V DC, making it universally compatible with global grid voltages (110V–240V AC).
• Integrated High-Voltage MOSFET: A defining feature of the HXJE is the integration of the power MOSFET directly onto the chip. This eliminates the need for an external power transistor, reducing component count and PCB real estate.
• Adjustable Output Current (SET Pin): The output current driving the LEDs is typically set via a single external resistor connected to a dedicated sense pin (often labeled REXT or SET). This allows designers to precisely tune brightness and power consumption without complex PWM circuitry.
• Thermal Foldback (Self-Protection): To prevent catastrophic failure in enclosed spaces (like a light bulb), the HXJE includes a thermal protection mechanism. As the internal junction temperature rises beyond a threshold (e.g., 130°C), the IC automatically reduces the output current, lowering the heat generation and preventing thermal runaway.

Non-Destructive Curve Tracing: Applying a controlled, low-power current-voltage (I-V) sweep to the pins of the "HXJE" IC against the ground pin maps out the internal ESD (Electrostatic Discharge) protection diodes. This helps identify digital I/O pins, power pins, and analog inputs before ever powering on the device. 4. Phase III: Advanced Imaging and Silicon Decapsulation

The "HXJE" code is a "top mark" or "marking code" used because the physical package is too small to fit the full part number. Primary Part Number: HX4004 or HX4004A. Manufacturer: Hexin Semiconductor. Cross-Reference/Analogs:
