BQ24617RGER Frequently Asked Questions (FAQs)

  • A good PCB layout for the BQ24617RGER involves placing the device close to the battery, using a solid ground plane, and keeping the high-current paths short and wide. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane for the battery voltage.
  • The sense resistor value depends on the maximum charge current and the desired accuracy. A good starting point is to use the formula Rsense = 0.1 ohms for a 1A charge current. Then, adjust the value based on the specific requirements of your application.
  • The EN (enable) pin is used to turn the charger on and off. When EN is high, the charger is enabled, and when EN is low, the charger is disabled. This pin can be connected to a GPIO pin of a microcontroller to control the charging process.
  • The BQ24617RGER has a built-in thermistor input (TS pin) that can be connected to a negative temperature coefficient (NTC) thermistor. The thermistor's resistance varies with temperature, and the BQ24617RGER can detect this variation to monitor the battery temperature.
  • The BQ24617RGER is a high-power charger with a wide input voltage range and a high level of integration. It's similar to other chargers like the BQ24650, but with a higher charge current capability and additional features like battery temperature monitoring.
