Instructions for BQ24133RGYR

1. Power Supply Connection:

   • Connect the input power supply to the VIN pin. Ensure the input voltage is within the specified range (4.0V to 5.5V).

2. Battery Connection:

   • Connect the battery to the BAT pin. Make sure the battery type and chemistry are compatible with the charger's regulation voltage.

3. Setting Charge Current:

   • The charge current can be set using an external resistor connected between the PROG pin and GND. Refer to the datasheet for specific resistor values corresponding to desired charge currents.

4. Monitoring Charging Status:

   • Use the STAT pin to monitor the charging status. This pin will indicate whether the IC is actively charging or if charging has been completed.

5. Thermal Considerations:

   • Ensure adequate heat dissipation as the device may enter thermal shutdown if the junction temperature exceeds 150°C.

6. Quiescent Current:

   • When not charging, the quiescent current should remain low (typically around 80μA) to minimize power consumption.

7. Safety Features:

   • The device includes over-temperature protection and will automatically shut down if the internal temperature exceeds the threshold.

For detailed design considerations and advanced configurations, refer to the full datasheet provided by the manufacturer.
