1 Introduction

1.1 bq2416x IC Features

The bq24160/161/163/168 integrates a synchronous PWM controller, power MOSFETs, input-current

sensing, high-accuracy current and voltage regulation, charge termination and power path management

into a small WCSP package. The charge parameters can be programmed through an I

C interface. Key IC

features include:

• High-efficiency, fully integrated, NMOS-NMOS, synchronous buck charger with 1.5-MHz frequency

• Integrated power FETs for up to 2.5-A charge rate

• Power path management between battery and system voltages

For details, see the bq24160/161/163/168 data sheet (SLUSAO0).

1.2 bq24160/161/163/168 EVM Features

The bq24160/161/163/168 evaluation module (EVM) is a complete charger module for evaluating

compact, flexible, high-efficiency, USB-friendly, switch-mode battery charge and power path management

solution for single-cell, Li-ion and Li-polymer battery-powered systems used in a wide range of portable

applications. Key EVM features include:

• 153-mm × 153-mm × 1.2-mm footprint for entire solution

• Input power connectors for both USB input and ac adapter

• Programmable battery voltage, charge current, input current, and status via I

C™ interface

• IN operating range of 4.2 V – 10 V (bq24160/161/163) or 4.2 V – 6 V (bq24168)

• USB operating range of 4.2 V – 6 V

• LED indication for status signals

• Test points for key signals available for testing purposes. Easy probe hook-up
