Application note
NiMH battery charger demonstration board through USB
based on the ST7FLIT15BY0
Introduction
This application note describes a NiMH battery charger demonstration board used with a
USB microcontroller. Basically, the battery charger demonstration board consists of two
identified sections:
■ a very low cost NiMH charger based on the ST7FLIT15BY0 microcontroller.
■ a USB microcontroller – ST72F60E2M1 – used to control the charger.
Chapter 1 describes the basic theory to connect a USB to the NiMH battery charger, and
also introduces the demonstration board STEVAL-ISB003V1. Chapter 2 describes how to
use the STEVAL-ISB003V1 demonstration board (USB to Li-Ion demonstration board) as
NiMH battery charger. Refer to UM0497 for more information on the STEVAL-ISB003V1.
