BQ2579x/BQ25792/BQ25798 - Buck-boost battery charger
This library supports several Bq2579x devices, namely:
- The BQ25798 is an I²C controlled, 1-4-cell, 5-A buck-boost solar battery charger with dual-input selector and MPPT.
- The BQ25792 is an I²C controlled, 5-A, 1-4 cell buck-boost charger with dual-input selector and USB PD 3.0 OTG output.

Usage
Warning: If using an ESP32, make sure to properly setup the I2C pins before creating the
I2cDevice
. Add a reference tonanoFramework.Hardware.ESP32
NuGet package and add the following code lines:
//////////////////////////////////////////////////////////////////////
// when connecting to an ESP32 device, need to configure the I2C GPIOs
// used for the bus
Configuration.SetPinFunction(21, DeviceFunction.I2C1_DATA);
Configuration.SetPinFunction(22, DeviceFunction.I2C1_CLOCK);
For other devices like STM32, please make sure you're using the preset pins for the I2C bus you want to use.
Hardware Required
- BQ25798 EVM
- Male/Female Jumper Wires
Circuit
- SCL - SCL
- SDA - SDA
- VCC - 5V
- GND - GND
Code
The following code creates an I2C configuration and instantiates a Bq25798 object. Then it prints the Minimum System Voltage detected by the device at boot. Last it enters a loop where it prints the current Vbus voltage each second.
I2cConnectionSettings settings = new I2cConnectionSettings(1, Bq25798.DefaultI2cAddress);
I2cDevice device = I2cDevice.Create(settings);
using (Bq25798 charger = new Bq25798(device))
{
Debug.WriteLine("");
Debug.WriteLine($"BQ25798 connected to I2C{device.ConnectionSettings.BusId}");
Debug.WriteLine("");
Debug.WriteLine($"Minimum System Voltage is config @ {charger.MinimalSystemVoltage.VoltsDc:N3}V");
while (true)
{
Debug.WriteLine($"Current Vbus: {charger.Vbus.VoltsDc:N3}V");
Debug.WriteLine("");
Thread.Sleep(1000);
}
}
