2.2
Recommended Test Equipment
2.2.1
Power Supplies
1. A power supply #1 (PS #1) capable of supplying 5 V at 2.5 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 circuit similar to the one shown in Figure 2 can simulate a battery when connected to a power
supply. Alternatively, a sourcemeter, capable of sourcing and sinking current can be used to simulate a
battery.

Figure 2. BAT_Load (PR1010) Schematic
2.2.3
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.
2.2.4
Computer
A computer with at least one USB port and a USB cable is required. The BQ24187 evaluation software
must be properly installed.
2.2.5
HPA172 Communication Kit (USB TO GPIO)
An HPA172 USB-to-I2C communication kit is required.
2.2.6
Software
Download BQ24187SW.zip from the charger's product folder, unzip the file, and double-click on the
SETUP.EXE file. Follow the installation steps.
Because the bq24187 has a watchdog timer, 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 PS #1 for 5-V, 2.5-A current limit and then turn off supply.
3. Connect the output of PS #1 in series with a current meter (CM #1) to J1 (IN).
4. Connect a voltmeter (VM #1) across J4 and J3 (IN and GND).
5. If BAT_Load as shown in Figure 1 is used, connect PS #2, set to approximately 3.7 V, to the input side
(PS #2+/-) of BAT_Load, then turn off PS #2.
6. Connect the output side of the battery or BAT_Load in series with current meter (multimeter) #2 (CM
#2) to J11 and J10 or J5 (BAT, GND). Ensure that a voltage meter (VM #2) is connected across J10 or
TP1 and J5 or TP7 (BAT and GND).
7. Connect VM #3 across J6 and J8 (DRV and GND).
8. Connect the HPA172 kit to J12 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.

Charge Voltage and Current Regulation of IN
Ensure that the steps in Section 2.3 are followed.
Move JP4 to LO.
Turn on PS #1.
Enable PS #2 and adjust PS #2 so that the voltage measured by VM #2, across BAT and GND,
measures 3.2 V ±50 mV.
Adjust the power supply so that VM #1 still reads 5 V ±100 mV, if necessary, then
Measure on CM #2 → ICHRG < 120 mA
Measure on CM #1 → IIN = 90–100 mA
Software setup:
• Press the READ button to obtain the current settings.
• Set Write On Change to ON, if not already set.
• Set Safety Timer to Disabled.
• Set Reset Watchdog Timer to update every 5 seconds.
• Uncheck Disable Charging if checked.
• Check Enable STAT/INT Outputs.
• Set Battery Regulation Voltage to 4.20 V.
• Set IN Input Current Limit to 2.0 A.
• Set Charge Current to 1000 mA.
• Click the READ button at the top of the window and confirm that the previous settings remain.
Enable PS #2 and adjust PS #2 so that the voltage measured by VM #2, across BAT and GND,
measures 3.8 V ±50 mV.
Adjust the power supply so that VM #1 still reads 5 V ±100 mV, if necessary, then
Measure on CM #2 → ICHRG = 1000 mA ±50 mA
Measure on CM #1 → IIN < 750 mA
Turn off PS #1 and PS #2.
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.
2. To observe the VIN-DPM feature, lower the current limit on PS #1.

Printed-Circuit Board Layout Guideline

www.ti.com
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 IC.
2. Place 4.7-µF input capacitor as close to PMID pin and PGND pin as possible to make the highfrequency 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 CS+ to GND must be connected between the CS+ 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 possible 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, 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.
