ACT2861

30V Buck-Boost Charger with Integrated MOSFETs and OTG

REG 0x04: Temperature Status (Read Only) (VM)

Bit

Name

Description

Comment

POK_VOUT

0: Output below 90%

1: Output above 92%

Indicator for Power OK in OTG or CHG mode. Uses

OTG_VOUT setting and measures VIN Pin during OTG.

Uses VTERM setting and VBATS Pin during Charge

Mode.

TH_BAT_DETECT

0: No Battery detected

1: Battery detected

Uses the voltage on TH pin. Can be used to detect

battery or battery at very cold temperature. If DIS_TH=1,

then register is always 0 – No battery detected.

OTG_COLD_DIS /

CHRG DIS_JEITA=1

OTG Mode OR (Charge

Mode AND DIS_JEITA=1)

0: OK

1: Below 0°C / -10°C input

If this bit is 1, then OTG or Charger mode is disabled

caused by Battery Below 0C or -10C depending on

OTG_COLD Register

OTG_HOT_DIS /

CHRG DIS_JEITA=1

OTG Mode OR ( Charge

Mode AND

DIS_JEITA=1 )

0: OK

1: Above 55°C / 60°C /

65°C Threshold

If this bit is 1, then OTG or Charger mode is disabled

caused by Battery Above 55C/60C/65C depending on

OTG_HOT[1:0] Register

CHRG_COLD

0: Normal Charge Mode

OR DIS_JEITA=1

1: Charging has stopped

with DIS_JEITA=0

In charge mode, if DIS_JEITA=0, then this bit goes high

when the battery temperature is less than 0°C and the

device is always disabled.

CHRG_COOL

0: Normal Charge Mode

OR DIS_JEITA=1

1: Reduced current or

charge suspended

In charge mode, if DIS_JEITA=0, then this bit goes high

when battery temperature is between 10°C and 0°C. In

this mode, the device may be disabled, or reduced

current.

This is controlled by Register 0x1C Bit [1:0].

CHRG_WARM

0: Normal Charge Mode

OR DIS_JEITA=1

1: Reduced charge

voltage and/or current

In charge mode, if DIS_JEITA=0, then this bit goes high

when battery temperature is between 45°C and 60°C. In

this mode, the device may be have reduced current or

reduced VTERM. This is controlled by Register 0x1C Bit

[5:2].

CHRG_HOT

0: Normal Charge Mode

OR DIS_JEITA=1

1: Charging has stopped

In charge mode, if DIS_JEITA=0, then this bit goes high

when the battery temperature is greater than 60°C and

the device is always disabled.
