Test Summary

Figure 2. BAT_Load (PR1010) Schematic

2.2.3 Load #2 Between SYS and GND

Although not required, a resistive load capable of sinking up to 3 A can be used.

2.2.4 Meters

Four equivalent voltage meters (VM#) and two equivalent current meters (CM#). The current meters must

be configured to measure 3-A current.

2.2.5 Computer

A computer with at least one USB port and a USB cable. The bq2416x evaluation software must be

properly installed.

2.2.6 HPA172 Communication Kit (USB to GPIO)

A HPA172 USB-to-I

C communication kit.

2.2.7 Software

Download the BQ2416xSW.zip file from the charger's product folder, unzip the file, and double-click on the

SETUP.EXE file. Follow the installation steps.

Because the bq24160, bq24161, and bq24163 have the watchdog timers enabled, it is recommended that

you set the software's Reset Watchdog Timer to reset every 5 seconds. Otherwise, after 30 seconds of

operation, the integrated circuit (IC) enters Default mode. Note that the 27-minute safety timer is not reset

by this function and eventually times out if charging does not complete, unless the Safety Timer Time

Limit is expanded or disabled via the GUI. One way to reset the safety timer is to allow the 30-second

watchdog timer to expire. See Figure 3 in the data sheet for more information about the timers.

Also, it is generally helpful to set the AutoRead and Write On Change functions, in the upper left of the

GUI window, to ON. The AutoRead function periodically updates the GUI with the IC status. The Write On

Change function writes any changes to the GUI check boxes, drop-down boxes, and registers to the IC.

Otherwise, the user is responsible for periodically pressing the READ button to find the IC instantaneous

status and WRITE button to write changes to the IC.
