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…
Part Number: BQ25120A What capacitor ratings should I pick?
For choosing the capacitor voltage we recommend looking into Pins Functions section of the BQ25120A datasheet, where the recommended capacitor value will be mentioned. For selecting the right…
Part Number: BQ25120A If using the BQ25120A as a standalone device, you should connect the ILIM/IPRETERM and ISET resistors to configure your current limit and fast charge parameter following the D/S recommendation.
If configuring the BQ25120A via I2C…
Part Number: BQ25120A Yes, you can change the system voltage (VSYS) and also disable the output on the SYS VOUT Control Register (0x06). The output can be programmable from 1.1V up to 3.3V.
Yes, you can also change the LDO/LS voltage and also disable…
Part Number: BQ25120A On the BQ25120A, both the /INT (Status Output) pin and /PG (Power Good) pins are an open-drain outputs, you can connect these pins via a pull up resistor or LED to the desired logic voltage. If monitoring the /INT or /PG pins via…
Part Number: BQ25120A Shipmode is the state of the device where is in the lowest power consumption. After manufacturing, the product will be on storage for a long time before reaching the consumers hands. Nowadays, we want to use the device out of the…
Part Number: BQ25120A Yes, you can configure the BQ25120A as a standalone device by configuring the current limit, fast charge current and termination current. To do so you will need to select the appropriate resistors for the ILIM, ISET and IPRETERM…
Part Number: BQ25120A Other Parts Discussed in Thread: BQ21061 The Manual Reset Input (/MR) is pulled up internally to BAT. To drive the signal with a microcontroller (MCU) you can use a N-Channel mosfet (nMOS) to mimic a "press" action from the MCU.…
Part Number: BQ25120A Other Parts Discussed in Thread: BQ25121A , BQ25120F3A In microcontroller applications, the watchdog timer is use to assure the host is still responsive and have not stopped operating. The BQ25120A has a 50-s watchdog timer that…
Part Number: BQ25120A On the BQ25120A the chip disable (/CD) input pin is used to disable the device and has dual functionality based on if the adapter (VIN) is present.
Battery Only Mode: When operating on battery only mode the /CD pin is used to…
