Recommended Test Procedure
The following test procedure may be useful for evaluating the charger IC outside of a real system, if no
battery is available to connect to the output and a simulated battery is needed.
2.4.1
Charge Voltage and Current Regulation of IN
1. Ensure that the Section 2.3 steps are followed.
2. Move JP2 (CE1 or CE) = HI and JP6 = HI.
3. Connect the output of Power Supply #1 (PS #1) in series with current meter number 1 (CM1) to J2 (IN,
GND).
4. Connect voltage meter number 1 (VM1) across J1 or TP1 and J3 or TP6 (IN, GND).
5. With PS2 disabled, turn on PS1.
6. Measure:
Measure on VM3 → V(J5/TP4(SYS),J9(GND)) = 4.3 ± 100 mV
Measure on VM4 → V(J13(DRV),J15(GND)) = 5.2 ± 200 mV
7. Move JP2 (CE1 or CE) = LO and JP6 = LO. Adjust the power supply so that VM1 still reads 6 V ± 100
mV if necessary.
8. Enable PS2 and adjust PS2 so that the voltage measured by VM2, across BAT and GND, measures
3.2 V + 50 mV
9. Measure and Observe:
Measure on CM2→ ICHRG = 2500 mA ± 150 mA
Measure on CM1 → IIN = 1800 mA ± 180 mA
Observe → D1 and D2 are on.
10. Turn off PS1 and PS2.

2.4.2
Charge Voltage and Current Regulation of USB
1. Ensure that the Section 2.3 steps are followed.
2. Move JP2 (CE1 or CE) = HI and JP6 = HI.
3. Connect the output of Power Supply number 1 (PS1) in series with current meter (multimeter) number
1 (CM1) to J4 and J8 or J6 (USB, GND).
4. Connect voltage meter 1 (VM1) across J4 or TP2 and J8 or TP5 (USB, GND).
5. With PS2 disabled, turn on PS1.
6. Measure:
Measure on VM3 → V(J5/TP4(SYS),J9(GND)) = 4.3 ± 100 mV
Measure on VM4 → V(J13(DRV),J15(GND)) = 5.2 ± 200 mV
7. Move JP2 (CE1 or CE) = LO and JP6 = LO while keeping the default settings for JP3 (USB3), JP4
(USB2) and JP5 (USB1). Adjust PS1 so that VM1 still reads 6 V ± 100 mV if necessary.
8. Enable PS2 and adjust PS2 so that the voltage measured by VM2, across BAT and GND, measures
3.2 V ± 50 mV.
9. Measure:
Measure on CM2→ ICHRG = 735 mA ± 75 mA
Measure on CM1 → IIN = 475 mA ± 50 mA
Observe → D1 and D2 are on.
10. Turn off PS1 and PS2.
2.4.3
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 PS2 voltage powering
BAT_Load (PR1010). Use VM2 across BAT and GND to measure the battery voltage seen by the IC.
2. To observe the VINDPM function, lower the current limit on PS1.
3. To observe battery supplement mode, apply a resistive load across SYS and GND that is higher than
the maximum charge current.

Printed-Circuit Board Layout Guideline
3
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 bq2416x.
2. Place 4.7-µF input capacitor as close to PMID pin and PGND pin as possible to make 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
occurs, 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.
