Requires only small ceramic capacitors for operation, saving PCB space. Protection:
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
The minimal bill of materials (BOM) allows the HX-JE to operate with just three low-cost ceramic capacitors: A 10
Formula: I_CHG = (K_SET / R_ISET) , where K_SET = 1200 for BQ24040. Example: For 500mA, R_ISET = 1200 / 0.5 = 2400 Ω (2.4k). hxje ic datasheet top
: Desoldering the broken chip clears the short. Replacing it with either an original HX4004A or a PS3120A restores the missing line immediately. Share public link
The IC utilizes a internally via an integrated feedback network. By regulating the internal charge cycles dynamically based on the load demand, it maintains a highly precise VOUTcap V sub cap O cap U cap T end-sub
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: Requires only small ceramic capacitors for operation, saving
The (commonly cross-referenced in industry databases as the HX4004A or PS3120 series) relies on a switched-capacitor charge-pump architecture. Unlike traditional boost regulators that store energy inside a magnetic field via an inductor, this IC utilizes dynamic internal switching matrices alongside minor ceramic flying capacitors to elevate voltage. Key Technical Parameters
Below is the standard circuit taken from the BQ24040 datasheet, which matches boards marked "HXJE":
Apply an external 4.0V bench power supply to the VINcap V sub cap I cap N end-sub Example: For 500mA, R_ISET = 1200 / 0
In conclusion, the HXJE IC datasheet is a critical resource for anyone working with these components. By understanding how to read and interpret the datasheet, you can ensure that you are using the IC correctly and safely. Whether you are a seasoned engineer or an electronics enthusiast, we hope that this article has provided you with valuable insights and information on the HXJE IC datasheet.
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
