Default Description

charger_state

0x34

[12:0]

256

Real time battery charger state indicator. Individual bits are mutually exclusive.

Enums: bat_detect_failed_fault = 4096,

battery_detection = 2048,

absorb_charge = 512,

charger_suspended = 256,

cc_cv_charge = 64,

ntc_pause = 32,

timer_term = 16,

c_over_x_term = 8,

max_charge_time_fault = 4,

bat_missing_fault = 2,

bat_short_fault = 1

charge_status

0x35

[5:0]

Charge status indicator. Individual bits are mutually exclusive and are only active in

charging states.

Enums: ilim_reg_active = 32,

thermal_reg_active = 16,

vin_uvcl_active = 8,

iin_limit_active = 4,

constant_current = 2,

constant_voltage = 1,

charger_off = 0

LIMIT_ALERTS_

REG

0x36

[15:0]

Limitalertregister.Thisinput/outputregisterindicatesthatanenabledalerthasoccurred.

Individual alerts are enabled in EN_LIMIT_ALERTS_REG. Writing 0 to any bit clears that

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

telemetry_valid_

alert

[15]

Alert that indicates that the telemetry system warm-up time has expired and valid

telemetry data is available from the serial port. 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_telemetry_valid_alert.

bsr_done_alert

[14]

Alert that indicates that the battery equivalent-series-resistance measurement is finished

and a result is available in bsr. This alert bit is cleared by writing it back to 0 with the

remainingbitsinthisregistersetto1s.Itcanalsobeclearedbyclearingen_bsr_done_alert.

vbat_lo_alert

[11]

Alert that indicates that vbat is below the value set by vbat_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_vbat_lo_alert.

vbat_hi_alert

[10]

Alert that indicates that vbat is above the value set by vbat_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_vbat_hi_alert.

vin_lo_alert

[9]

Alert that indicates that vin is below the value set by vin_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_vin_lo_alert.

vin_hi_alert

[8]

Alert that indicates that vin is above the value set by vin_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_vin_hi_alert.

vout_lo_alert

[7]

Alert that indicates that vout is below the value set by vout_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_vout_lo_alert.
