Default Description

vout_hi_alert

[6]

Alert that indicates that vout is above the value set by vout_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_vout_hi_alert.

iin_hi_alert

[5]

Alert that indicates that iin is above the value set by iin_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_iin_hi_alert.

ibat_lo_alert

[4]

Alert that indicates that ibat is below the value set by ibat_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_ibat_lo_alert.

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_

[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.

charger_

suspended_alert

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.

ntc_pause_alert

[5]

Alert that indicates that the battery charger is in the ntc_pause 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_ntc_pause_alert.

timer_term_alert

[4]

Alert that indicates that the battery charge is in the timer_term 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_timer_term_alert.

Alert that indicates that the battery charge is in the c_over_x_term 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_c_over_x_term_alert.

max_charge_time_

fault_alert

[2]

Alert that indicates that the battery charge is in the max_charge_time_fault 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_max_charge_time_alert.
