Battery voltage and current sense input. Bypass it with a ceramic capacitor (minimum 0.1 μF) to PGND if CSOUT E4 I there are long inductive leads to battery. Charger input voltage. Bypass it with a 1- μF ceramic capacitor from VBUS to PGND. It also provides power VBUS A1, A2 I/O to the load during boost mode (bq24153A/8 only) . Connection point between reverse blocking FET and high-side switching FET. Bypass it with a minimum of PMID B1, B2, B3 I/O 3.3- μF capacitor from PMID to PGND. SW C1, C2, C3 O Internal switch to output inductor connection. Bootstrap capacitor connection for the high-side FET gate driver. Connect a 10-nF ceramic capacitor (voltage BOOT A3 I/O rating ≥ 10 V) from BOOT pin to SW pin. PGND D1, D2, D3 Power ground Charge current-sense input. Battery current is sensed across an external sense resistor. A 0.1- μF ceramic CSIN E1 I capacitor to PGND is required. SCL A4 I I2C interface clock. Connect a 10-k Ω pullup resistor to 1.8V rail (VAUX= VCC_HOST) SDA B4 I/O I2C interface data. Connect a 10-k Ω pullup resistor to 1.8V rail (VAUX= VCC_HOST) Charge status pin. Pull low when charge in progress. Open drain for other conditions. During faults, a 128- μs STAT C4 O pulse is sent out. STAT pin can be disabled by the EN_STAT bit in control register. STAT can be used to drive a LED or communicate with a host processor. Internal bias regulator voltage. Connect a 1 µF ceramic capacitor from this output to PGND. External load on VREF E3 O VREF is not recommended. Charge disable control pin. CD=0, charge is enabled. CD=1, charge is disabled and VBUS pin is high CD E2 I impedance to GND. In 15min mode, Setting CD=1 resets the 15min timer; while in 32s mode, Setting CD=1 will NOT reset the 32-second timer. Boost mode enable control or input current limiting selection pin. When OTG is in active status, bq24153A/8 is forced to operate in boost mode. It has higher priority over I2C control and can be disabled using the OTG D4 I control register. At POR while in 15-min mode, the OTG pin is default to be used as the input current limiting (bq24153A/8 only) selection pin. The I2C register is ignored at startup. When OTG=High, IIN_LIMIT=500mA and when OTG=Low, IIN_LIMIT=100mA. Safety limit register reset control. When SLRST=0, bq24156A/9 resets all the safety limits (06H) to default SLRST D4 I values, regardless of the write actions to safety limits registers (06H). When SLRST=1, bq24156A/9 can (bq24156A/9 only) program the safety limit register until any write action to other registers locks the programmed safety limits.
