Part Number: BQ24040
Dear TI staff
I am using BQ24040 to charge Li-Ion Battery on my application.
The below information is my configured.
IN PIN is connected 5V
OUT PIN is Vbatt
TS PIN --> connect 10k ohm to ground
ISET2 PIN --> 10k ohm to Vbatt
PRETERM PIN --> 2k ohm to ground
ISET PIN --> 1.1k ohm (Charge current should be between 463.6mA - 518.1mA relate to Kiset 510 Aohm - 560 Aohm; see Fast charge current factor, page 7 in datasheet)
When I connected 5V input, the charge current as I measure at input side is 0.45A, that the charge current out of my expectation.
Could you suggest me where I wrong?
Remark: Actually charge current as I expect is 540/1100 = 490mA
Best regards,
Narukom S.
