1.1 Introduction

This user's guide describes the characteristics, operation, and functionality of the BQ25960H Evaluation Module (EVM), which is a complete evaluation system for the BQ25960H IC. The BQ25960H is a 8 A switched capacitor battery charger in WCSP package for 1-cell Li-Ion and Li-Polymer batteries.

The user's guide describes the equipment, test setup, and software required to operate the EVM. A complete schematic diagram, printed-circuit board (PCB) layouts, and bill of materials (BOM) are also included in this document. Throughout this user guide, the abbreviations and terms EVM, BQ25960HEVM, BMS082, and evaluation module are synonymous with the BQ25960H EVM.

Users can configure the EVM for either single BQ25960H operation or dual BQ25960H operation based on the jumper settings described in the next section. In single BQ25960H operation, only U1 charges the battery. In dual BQ25960H operation, U1 acts as the primary charger, and U2 acts as the secondary charger.

This EVM does not include the EV2400 interface board. To evaluate the EVM, an EV2400 interface board must be ordered separately.

WARNING:

Hot surface! Contact can cause burns. Do not touch!

Some components can reach high temperatures >55℃ when the board is powered on. The user must not touch the board at any point during operation or immediately after operating, as high temperatures can be present.
