Hi, I am interesting in use the BQ24038EVM with 12 Vdc input. I have the next configuration:
JMP1: to GND [0.1 mA]
JMP2, pin2 tied to 3.3 Volts of LDO. [AC selection]
JMP3, pin2 tied to 3.3 Volts of LDO. [charger enabled]
JMP5, POP jumper in 1-2 position. [STAT1 led D2 (green) activated]
JMP4, POP jumper in 1-2 position. [STAT2 led D3 (red) activated]
JMP7, NOPOP (selected 4.2 Volts)
JMP6, POP jumper in 1-2 position. [PG led D5 (green) activated]
I connect to the power input 12 Vdc but I notice that the BQ24038 heated too.
Is this normal?
I've read in the data sheet of BQ2403X, than the supply voltage from AC input is min: 4.35 Volts and max: 16 Volts, then I can use a input supply of 12 Vdc.
Than you very much.
