Default Description

die_temp_hi_alert

[3]

Alert that indicates that die_temp is above the value set by die_temp_hi_alert_limit. This

alert bit is cleared by writing it back to 0 with the remaining bits in this register set to

1s. It can also be cleared by clearing en_die_temp_hi_alert.

bsr_hi_alert

[2]

Alert that indicates that bsr is above the value set by bsr_hi_alert_limit. This alert bit is

cleared by writing it back to 0 with the remaining bits in this register set to 1s. It can

also be cleared by clearing en_bsr_hi_alert.

thermistor_voltage_

hi_alert

[1]

Alert that indicates that thermistor_voltage is above the value set by thermistor_voltage_

hi_alert_limit. This alert bit is cleared by writing it back to 0 with the remaining bits in

this register set to 1s. It can also be cleared by clearing en_thermistor_voltage_hi_alert.

thermistor_voltage_

lo_alert

[0]

Alert that indicates that thermistor_voltage is below the value set by thermistor_voltage_

lo_alert_limit. This alert bit is cleared by writing it back to 0 with the remaining bits in

this register set to 1s. It can also be cleared by clearing en_thermistor_voltage_lo_alert.

CHARGER_STATE_

ALERTS_REG

0x37

[12:0]

Alert that indicates that charger states have occurred. Individual bits are enabled by

EN_CHARGER_STATE_ALERTS_REG. Writing 0 to any bit while writing 1s to the

remaining bits clears that alert. Once set, alert bits remain high until cleared or disabled.

bat_detect_failed_

fault_alert

[12]

Alert that indicates a bat_detect_failed_fault. This alert bit is cleared by writing it back

to 0 with the remaining bits in this register set to 1s. It can also be cleared by clearing

en_bat_detect_failed_fault_alert.

battery_detection_

alert

[11]

Alert that indicates the battery charger is performing battery_detection. This alert bit is

cleared by writing it back to 0 with the remaining bits in this register set to 1s. It can

also be cleared by clearing en_battery_detecttion_alert.

equalization_charge_

alert

[10]

Alert that indicates that the battery charger is in the equalize_charge phase. This alert

bit is cleared by writing it back to 0 with the remaining bits in this register set to 1s. It

can also be cleared by clearing en_equalize_charge_alert.

absorb_charge_alert

[9]

Alert that indicates that the battery charger is in the absorb_charge phase. This alert bit

is cleared by writing it back to 0 with the remaining bits in this register set to 1s. It can

also be cleared by clearing en_absorb_charge_alert.

charger_suspended_

alert

[8]

Alert that indicates the battery charger is in the charger_suspended state. This alert bit

is cleared by writing it back to 0 with the remaining bits in this register set to 1s. It can

also be cleared by clearing en_charger_suspended_alert.

cc_cv_charge_alert

[6]

Alert that indicates that the battery charge is in the cc_cv_charge phase. This alert bit

is cleared by writing it back to 0 with the remaining bits in this register set to 1s. It can

also be cleared by clearing en_cc_cv_charge_alert.

bat_missing_fault_

alert

[1]

Alert that indicates that a bat_missing_fault has been detected. This alert bit is cleared

by writing it back to 0 with the remaining bits in this register set to 1s. It can also be

cleared by clearing en_bat_missing_fault_alert.

bat_short_fault_alert

[0]

Alert that indicates that a bat_short_fault has been detected. This alert bit is cleared

by writing it back to 0 with the remaining bits in this register set to 1s. It can also be

cleared by clearing en_bat_short_fault_alert.

CHARGE_STATUS_

ALERTS_REG

0x38

[5:0]

Alerts that charge_status indicators have occurred. Individual bits are enabled by

EN_CHARGE_STATUS_ALERTS_REG. Writing 0 to any bit clears that alert. Once set,

alert bits remain high until cleared or disabled.

[5]

Alert that indicates that charge_status is ilim_reg_active. This alert bit is cleared by

writing it back to 0 with the remaining bits in this register set to 1s. It can also be cleared

by clearing en_ilim_reg_active_alert.

thermal_reg_active_
