Hxje Ic Datasheet Top

Positive terminal attachment point for the external flying charge-pump capacitor. Functional Cross-References & Alternates

If the exact component labeled is unavailable via your default supply house, engineers can reliably check for alternative factory codes. Component catalogs on Aliexpress and global component distributors index this top marking interchangeably under the manufacturing parts HX4004 , HX4004A , and the PS3120A voltage doubler family.

When reading the HXJE IC datasheet top, it's essential to understand the various sections and parameters. Here's a brief guide:

In most cases, a 4-character marking like HXJE is one of three things:

Key features (what to scan first)

Check the voltage levels across the bypass capacitors directly touching and Pin 1 ( VOUTcap V sub cap O cap U cap T end-sub ) using a digital multimeter. VINcap V sub cap I cap N end-sub is between 2.7V and 4.5V but VOUTcap V sub cap O cap U cap T end-sub stays close to or matches VINcap V sub cap I cap N end-sub Positive terminal attachment point for the external flying

): Regulated output voltage pin. Bypass this pin with a low-ESR ceramic capacitor to the ground. System ground reference connection. Pin 3 (EN / VENcap V sub cap E cap N end-sub

Keep the loop areas of the flying capacitor exceptionally short. Because charge pumps dump current packages at a 360 kHz frequency, long trace lines behave like small antennas, introducing high-frequency ringing to nearby sensitive analog circuits—such as pre-amplifiers or RF receivers.
