Hi Dialog teams,

3V is the cut-off voltage of the battery(15mAH), but the battery voltage is discharged to 1.8V. Why？

The following is param.

 

/*Modify by philip for 15mA battery E*/
#define dg_configBATTERY_TYPE                   (BATTERY_TYPE_LICOO2)
#define dg_configBATTERY_CHARGE_CURRENT         1       // 10mA
#define dg_configBATTERY_PRECHARGE_CURRENT      20      // 2.1mA
#define dg_configBATTERY_CHARGE_NTC             1       // disabled
#define dg_configBATTERY_CHARGE_VOLTAGE         0xA     // 4.2V
#define dg_configPRECHARGING_THRESHOLD          (2462)  // 3.006V
#define dg_configCHARGING_THRESHOLD             (2498)  // 3.05V
#define dg_configPRECHARGING_TIMEOUT            (30 * 60 * 100)  // N x 10msec
#define dg_configBATTERY_LOW_LEVEL              2496    // 3.05v
/*Modify by philip for 15mA battery X*/

Hi There,

Hi There,

Please take a look at the AN-B-035 Application Note: DA1468x Battery Charging and see Table 5: Configuration Settings for Specific Battery Types. The charging voltage is 4.2 V. Can you please explain what is the issue you have?

Thanks, PM_Dialog
