Texas Instruments bq25302EVM Charger Evaluation Module (EVM)

Texas Instruments bq25302EVM Charger Evaluation Module (EVM) is used to evaluate the bq25302 device. The Texas Instruments bq25302 is a highly integrated 2A standalone one cell, 5V, 1.2MHz synchronous switch-mode buck battery charger with programmable charge voltage.

Features

  • High-efficiency 1.2MHz synchronous switch-mode buck charger
  • Single input to support USB input adapters
  • Input voltage dynamic power management (VINDPM)
  • 1µA low battery leakage current with adapter unplugged
  • Supports 300mA to 2A charge current

Required Equipment

  • Power Supply #1 (PS1)
    • A power supply capable of supplying 5V at 3A is required
    • While this part can handle larger voltage and current, it is not necessary for this procedure
  • Power Supply #2 (PS2)
    • A power supply capable of supplying 5V at 1A is required
  • Loads
    • Load #1 (4-Quadrant Supply, Constant Voltage < 4.5V): a Kepco Load, BOP, 20-5M, DC 0 to ±20V, 0 to ±5A (or higher)
    • Alternative Option: A 0–20 V/0–5A, > 30W DC electronic load set in a constant voltage loading mode
  • Meters
    • 4x Fluke 75 multimeters (equivalent or better)
