Key Features & Applications Full part number (e

Internal Sensing: Unlike traditional boost controllers, the HX-JE is "non-sensing," meaning it reduces the need for external feedback resistors or sensing networks in certain configurations, making it a "plug-and-play" solution for simple voltage stepping.

Power Management: Includes an Enable (EN) feature that allows the system to enter a low-power state when the boost function is not required, extending battery life in portable devices.

Typical Uses: Powering LED strings, driving small motors, and providing regulated power in battery-operated consumer electronics. Sourcing & Documentation

The HX-JE is widely available through electronic component distributors such as Jotrin Electronics and Alibaba. If you require the full technical PDF for precision timing or thermal curves, it is recommended to request the official document directly from the manufacturer or through specialized archives like Scribd.

1. Chip Overview and Features

The HXJE (often associated with manufacturers like Hengjia or similar semiconductor foundries) is typically designed as a high-performance power switch. Depending on the specific suffix variant (e.g., HXJE1, HXJE2), it may function as a buck converter or a dedicated LED driver.

Key Datasheet Highlights:

Topology: Usually supports Buck, Buck-Boost, or isolated Flyback topologies.
Integration: Built-in high-voltage power MOSFET (typically 600V or 700V rating), reducing external component count.
Efficiency: Features low $R_DS(on)$ for reduced conduction losses and high conversion efficiency.
Protection Mechanisms: Comprehensive suite including Over-Voltage Protection (OVP), Over-Temperature Protection (OTP), and Short Circuit Protection (SCP).

How to Set Charge Current:

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).
