Quick Setup Guide

1. Insert shunts on left two pins of H6, H5 for normal operation

and H4 to disable timeout if needed.

2. Connect power supply (PS1) in series with a current meter (I1)

to connector IN+.

3. Connect power supply (PS2) in series with a current meter (I2)

to VBAT pin of J2.

4. Connect electronic load (E-load) setting at 2.2A to VBAT pin

and ground.

5. Connect a voltage meter (V2) on TP6 to measure voltage on

VBAT.

6. Place a scope probe on the connector of TP14 to monitor

switching waveform.

7. Set input supply PS1 voltage between 4.5V to 14V for 1-cell

charge and 9V to 14V for 2-cell charge.

8. Set PS2 so that V2 measures 3.6V on VBAT for 1-cell and 7V

for 2-cell.

9. Turn on PS1. LED2 will turn on red indicating power good.

10. Turn on PS2 and E-load. LED1 will turn on green indicating

charging in progress.

11. Without shunts on JP8 and JP9, current meter I2 will measure

500mA ±10% charge current.

12. Insert a shunt on JP8. The resistance on the ISET1 pin

becomes 33.3kΩand I2 will measure 1.5A±10% charge

current.

13. Insert shunt on JP9. The resistance on the ISET1 pin becomes

25kΩand I1 will measure 2A±10% charge current.

14. Lower the voltage on PS2 until V2 measures 2.5V for 1-cell

and 5V for 2-cell. The charger will become trickle mode. I2 will

measure around 70mA trickle charge current.

15. Insert a shunt on JP10. I2 will measure around 140mA trickle

charge current. For Steps 11 to 15, you should see 1.2MHz

switching waveform on the scope.

16. Lower the voltage on PS2 until V2 measures less than 2.5V for

1-cell and less than 5V for 2-cell. The charger will charge in

LDO mode current. I2 will measure around 50mA LDO

current. The charge stops switching in this mode.

17. Slowly increase the voltage on PS2; the charge current into the

PS2 reduces. As current continues to reduce and reaches

around 100mA, the end-of-charge event happens and the

charger stops charging. At this point, V2 should measure 4.2V,

±1% for 1-cell and 8.4V, ±1% for 2-cell. STAT1 toggles high, and

LED2 turns off. Remove the shunt from JP10, the end-of-charge

current changes to 50mA.

18. Charging efficiency can be calculated by

(VO*IO)/(VIN*IIN)*100. The voltage and current can be read

from V1, I1, V2 and I2.

TABLE 2. DESCRIPTION OF JUMPERS

JUMPER DESCRIPTION

H1 The jumper installed to connect R3 and R4 to VBIAS pin as power supply to the LED1 and LED2

H2 The jumper installed to short ISET2 pin to ground

H3 The jumper to short ISET1 pin to ground

H4 If a shunt is inserted on H4, TIME pin is shorted to ground, and the TIMEOUT function will be disabled. If H4 is open, TIMEOUT function

will be enabled and timeout can be set with capacitor at the pin

H5 If a shunt is installed on H5, VBIAS will be scaled down to 2.5V at the RTH pin by the resistive divider of R12 and R13 and the charger

will operate in normal mode. If H5 is open, RTH pin will be pulled high, and the charger is in suspend mode

H6 It is a 3 pin jumper. If a shunt is inserted on the left two pins, the EN pin is connected to ground and the charger is enabled. If a shunt

is inserted on the right two pins, the EN pin is connected to VBIAS and the charger is disabled

JP8 Parallels an additional 50kΩresistor to ISET1 pin such that the charge current will be set at 1.5A with JP9 open

JP9 Parallels an additional 100kΩresistor to ISET1 pin such that the charge current will be set at 1A with JP8 open. If both JP8 and JP9

are inserted, the charge current will be 2A. If both JP8 and JP9 are open, the charge current will be 500mA

JP10 Parallels an additional 600kΩresistor to ISET2 pin to set a trickle charge current of 140mA
