Texas Instruments bq25898CEVM Evaluation Module (EVM)
Texas Instruments bq25898CEVM Evaluation Module (EVM) is a complete charger module for evaluating the bq25989C. The Texas Instruments bq25898C is a highly-integrated switch-mode battery charge management and system power path management device in the WCSP package. This battery charge management device is for a single cell Li-Ion and Li-polymer battery in a wide range of smartphone and tablet applications.Features
- Input voltage range of 3.9V to 14V and charge current up to 4A
- I2C communication with input current limit initially set by D+/D- detection
- LED indication for status signals
- Test points for key signals available for testing purposes
- Jumpers for a different circuit configuration
Required Equipment
- Power Supplies
- Power supply #1 (PS#1): a power supply capable of supplying 5V at 1A is required
- While this part can handle larger voltage and current, it is not necessary for this procedure
- Load #1 (4-quadrant supply, constant voltage < 4.5V)
- A 0–20V/0–5A, > 30W system, dc electronic load and setting as constant voltage load mode or Kepco load: BOP 20–5M, DC 0 to ±20V, 0 to ±5A (or higher)
- Load #2 use in boost mode
- PMID to GND load, 10Ω, 5W, or greater
- Power supply #1 (PS#1): a power supply capable of supplying 5V at 1A is required
- Meters
- Six Fluke 75 multimeters (equivalent or better) or four equivalent voltage meters and two equivalent current meters, the existing meters must be capable of measuring 5A current
- Computer
- A computer with at least one USB port and a USB cable
- The bq25898xEVM evaluation software must be properly installed
- USB-to-GPIO communication kit EV2300/EV2400 USB-based PC interface board
