Hotchip – HT4928S Ver1.1 English PDF

The Hotchip HT4928S english datasheet

The HT4928S is a highly integrated mobile power supply Management chip with a built-in charge management module, an LED indicator Block, a boost discharge management module and is available in a small SOP8 Package. The periphery can be composed of very few components for a powerful mobile power solution.

It may or may not be the management chip that is on this module, described on Aliexpress as “5V-Step-Up-Power-Module-Lithium-Battery-Charging-Protection-Board-Boost-Converter-LED-Display-USB

With more than a little help from Google Translate, I translated the Chinese HT4928S datasheet

to English. Enjoy!
