Part Number: BQ25120A
The charger can enter shipmode by:
To enter shipmode on the BQ25120A, the device should be operating on battery-only mode (V IN < V UVLO ), and /CD and /MR must be high. Then you can:
Send the I2C command EN_SHIPMODE = 1 on the…
Part Number: BQ25120A The maximum discharge current you can pull from the PMID output depends on if adapter (VIN) is present or not. Operating on BAT only mode, the max current from PMID will be your Current Limit on Discharge Mode (IBAT_OCP). When the…
Part Number: BQ25120A The BQ25120A is a highly integrated power management unit which includes integrated power rails: a buck converter (SW/SYS) and a linear regulator (LDO/LS). The charger is also part of our power path family which includes the PMID…
Part Number: BQ25120A The BQ25120A implements a simple voltage battery monitor which can be used to determine the depth of discharge of your battery. A high-level representation of the circuit can be seen on Figure 17 of the datasheet. Table 2 provides…
Part Number: BQ25120A The dynamic power path management (DPPM) of the BQ25120A will separate the charging current from system current. When you have a valid IN source, current is shared at the PMID between charging the battery and providing system load…
