Charger Status1 Register (Address 05).

Charger Status2 Register (Address 06).

Addr: 05

Charger Status1

These bits show the status of the charger.

Bit

Bit Name

Default

Access

Bit Description

ChDet

Bit is set when charge adapter has been detected on pin VBUS

CCM

Bit is set when charger is in Constant current mode

Resume

Bit is set when battery voltage has dropped below resume level

Trickle

Bit is set when charger is in trickle charge mode

CVM

Bit is set when charger is in top-off charge mode (constant voltage

mode)

EOC

Bit is set when charging has been terminated. Bit is cleared

automatically when chg_en is cleared or charging is resumed.

Battemp_hi

Bit is set, if temperature is greater than 50 or 55°C. Bit is evaluated if

charger is detected.

NoBat

Bit is set when battery detection circuit indicates that no battery is

connected to the system. This is done by measuring the NTC value.

ntc_on has to be 1.

Addr: 06

Charger Status2

These bits show the status of the charger.

Bit

Bit Name

Default

Access

Bit Description

LowBat

Set, if VBAT<2V

OVBat

Set, if VBAT> 1.17*VCHARGE

LowBus

Set, if VBUS<3.8V

OVBus

Set, if VBUS>6.5V

UVLBus

Set, if VBUS<3.3V

Boost_act

Set, if boost mode active

Boost_err

Set, if boost error active. (Overcurrent of booster for more than

debounce time, VBAT<2.5V, VBUS>6.5V or current limit is active

Stop charging

Set if charger is stopped because of the following reason:

- Timeout timer expired

- NTC temperature error (Hightemp)

- OVBus set

- OVBat set

- UVLBus set

- Die temp>140deg (ov_temp_140 set)
