Recommended Test Equipment
2.2.1
Power Supplies
1. Power Supply #1 (PS #1) capable of supplying 6 V at 3 A is required.
2. If not using a battery as the load, then power supply #2 (PS #2) capable of supplying up to 5 V at 5 A
is required to power the circuit shown in Figure 2.
2.2.2
Load #1 Between BAT and GND
Testing with an actual battery is the best way to verify operation in the system. If a battery is not available,
then a battery or circuit similar to the one shown inFigure 2 can simulate a battery when connected to a
power supply.

2.2.4
Meters
Four equivalent voltage meters (VM #) and two equivalent current meters (CM #) are required. The current
meters must be able to measure 3-A current.
2.2.5
Computer
A computer with at least one USB port and a USB cable is required. The bq2416x evaluation software
must be properly installed.
2.2.6
HPA172 Communication Kit (USB TO GPIO)
A HPA172 USB-to-I2C communication kit is required.
2.2.7
Software
Download BQ2416xSW.zip 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 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 activate the Write On Change functions, in the upper left of the GUI window,
to ON. The Write On Change function writes any changes to the GUI's check boxes, drop-down boxes,
and registers to the IC. Otherwise, the user must click the WRITE button to write changes to the software.
It is recommended that the user periodically click the READ button to find the IC's instantaneous status.
Alternatively, the AutoRead function can be activated to periodically update the GUI with the IC's status.
2.3
Recommended Test Equipment Setup
1. For all power connections, use short, twisted-pair wires of appropriate gauge wire for the amount of the
current.
2. Set Power Supply #1 (PS #1) for 6-V, 3-A current limit and then turn off supply.
3. If BAT_Load as shown in Figure 1 is used, connect Power Supply #2 (PS #2) set to approximately 3.6
V to the input side (PS #2+/-) of BAT_Load, then turn off PS #2.
4. Connect the output side of the battery or BAT_Load in series with current meter (multimeter) #2 (CM
#2) to J2 and J6 or J3 (BAT, GND). Ensure that a voltage meter is connected across J2 or TP3 and J6
or TP9 (BAT, GND).
5. Connect VM #3 across J10 or TP7 and J14 or TP9 (SYS, GND).
6. Connect VM #4 across J15 or TP5 and J14 or TP9 (DRV, GND).
7. Connect J17 to HPA172 kit by the 10-pin ribbon cable. Connect the USB port of the HPA172 kit to the
USB port of the computer. The connections are shown in Figure 3.

Helpful hints
1. To observe the taper current as the battery voltage approaches the set regulation voltage, allow the
battery to charge or, if using BAT_Load (PR1010), slowly increase the PS #2 voltage powering
BAT_Load (PR1010). Use VM #2 across BAT and GND to measure the battery voltage seen by the IC.

Printed-Circuit Board Layout Guideline
www.ti.com
2. To observe the VINDPM function, lower the current limit on PS #1.
3. To observe battery supplement mode, apply a resistive load across SYS and GND that is higher than
the maximum charge current.
3
Printed-Circuit Board Layout Guideline
1. To obtain optimal performance, the power input capacitors, connected from the PMID input to PGND,
must be placed as close as possible to the bq2416x
2. Place 4.7-µF input capacitor as close to PMID pin and PGND pin as possible to make the
high-frequency current loop area as small as possible. Place 1-µF input capacitor GNDs as close to
the respective PMID capacitor GND and PGND pins as possible to minimize the ground difference
between the input and PMID_.
3. The local bypass capacitor from SYS to GND must be connected between the SYS pin and PGND of
the IC. The intent is to minimize the current path loop area from the SW pin through the LC filter and
back to the PGND pin.
4. Place all decoupling capacitors close to their respective IC pins and as close as to PGND (do not place
components such that routing interrupts power stage currents). All small control signals must be routed
away from the high-current paths.
5. The PCB must have a ground plane (return) connected directly to the return of all components through
vias (two vias per capacitor for power-stage capacitors, one via per capacitor for small-signal
components). It is also recommended to put vias inside the PGND pads for the IC, if possible. A star
ground design approach is typically used to keep circuit block currents isolated (high-power/low-power
small-signal) which reduces noise-coupling and ground-bounce issues. A single ground plane for this
design gives good results. With this small layout and a single ground plane, no ground-bounce issue
exists, and having the components segregated minimizes coupling between signals.
6. The high-current charge paths into IN, USB, BAT, SYS, and from the SW pins must be sized
appropriately for the maximum charge current in order to avoid voltage drops in these traces. The
PGND pins must be connected to the ground plane to return current through the internal low-side FET.
7. For high-current applications, the balls for the power paths must be connected to as much copper in
the board as possible. This allows better thermal performance because the board conducts heat away
from the IC.
