TERMINAL FUNCTIONS TERMINAL I/O DESCRIPTION NAME NO. AC 4 I Charge input voltage from AC adapter ACPG (1) 18 O AC power-good status output (open-drain) BAT 5, 6 I/O Battery input and output. CE 9 I Chip enable input (active high) DPPM 13 I Dynamic power-path management set point (account for scale factor) ISET1 10 I/O Charge current set point for AC input and precharge and termination set point for both AC and USB Charge current set point for USB port. (High = 500 mA, Low = 100 mA) For bq24032, see half-charge ISET2 7 I current mode using ISET2. (bq24039 only) Boot-up (Low = enabled, High = disabled); TERM Detect (High = 250 nVm, Low = 100 ISET3(2) 8 I mV), USB MODE current multiplier (High = x2 of ISET2, Low = x1 of ISET2). LDO 1 O 3.3-V LDO regulator OUT 15, 16, 17 O Output terminal to the system PG (1) 18 O AC or USB power-good status output (open-drain) PSEL(2) 8 I Power source selection input (Low for USB, High for AC) STAT1 2 O Charge status output 1 (open-drain) STAT2 3 O Charge status output 2 (open-drain) TMR 14 I/O Timer program input programmed by resistor. Disable safety timer and termination by tying TMR to LDO. TS 12 I/O Temperature sense input USB 20 I USB charge input voltage USBPG (1) 19 O USB power-good status output (open-drain) VBSEL(3) 19 I Battery charge voltage selection Ground input (the thermal pad on the underside of the package) There is an internal electrical connection between the exposed thermal pad and VSS pin of the device. The exposed thermal pad must be VSS 11 – connected to the same potential as the VSS pin on the printed-circuit board. Do not use the thermal pad as the primary ground input for the device. VSS pin must be connected to ground at all times. (1) Pin 18 is PG for bq24038 and ACPG for bq24030/1/2/2A/5/9. (2) Pin 8 is PSEL for bq24030/1/2/2A/5/8 and ISET3 for bq24039. (3) Pin 19 is VBSEL for bq24038 and USBPG for bq24030/1/2/2A/5/9. 9 |
