CONDITION
CHARGING_CONTROLLED_STATE = 1 AND THERM_HOT
Changes from 0 to 1 AND THERM_UR = 0
ACTION
CHARGING_NONE_STATE = 1
The Charger_Controller Stops Charging the Battery. It Cannot
“Wake Up” Charge Again Until Condition 15 Is Met. It Can Supply
“Controlled Charge” to the Battery If Conditions 8 or 9 Are Met
CHARGING_NONE_STATE = 1
The Charger_Controller Stops Charging the Battery. It Cannot
“Wake Up” Charge Again Until Condition 15 Is Met. It Can Supply
“Controlled Charge” to the Battery If Conditions 8 or 9 Are Met
CHARGING_CONTROLLED_STATE = 1
INHIBIT_CHARGE Asynchronously Inhibits Charging Without
Affecting the Charger_Controller State Machine. This Means the Charger
Stops Charging the Battery but Continues to Accept New
ChargingCurrent() and ChargingVoltage() Commands, Continues to
Monitor the Battery Thermistor Input and Continues to Track the
Communication Time-Out. It Will Resume Charging the Battery If
INHIBIT_CHARGE Is Cleared to 0, Possibly at Different Current and
Voltage If New Commands Have Been Sent in the Interim
CHARGING_RESET_STATE= 1
The Charger_Controller Is Set to Its Power-On Default State
13
CHARGING_CONTROLLED_STATE = 1 AND THERM_UR
Changes from 1 to 0 AND THERM_HOT = 1
14
CHARGING_CONTROLLED_STATE = 1
AND INHIBIT_CHARGE Is Set to 1
15
ANY STATE
The Charger_Controller Is in Any State AND (the Battery Is Removed
OR AC_PRESENT = 0 OR a 1 Is Written to POR_RESET)
NOTE:
Condition 15 Takes Precedence Over Any Other Condition.
(CHARGING_CONTROLLED_STATE = 1) OR
CHARGING_WAKE-UP_STATE = 1) AND
A 1 Is Written to RESET_TO_ZERO
16
CHARGING_NONE_STATE = 1
The Charger_Controller Stops Charging the Battery. It Cannot
“Wake Up” Charge Again Until Condition 15 Is Met. It Can Supply
“Controlled Charge” to the Battery If Conditions 8 or 9 Are Met.
The Valid Charge Command Timer Is Cleared When RESET_TO_ZERO =
1. This Prevents Charging from Continuing Until After a Valid
ChargeCurrent() and ChargeVoltage() Pair Is Received
Alert SMHost of Change by Setting INTB = 0
18
ANY STATE AND
AC_PRESENT Transitions 0 to 1 or 1 to 0 OR
BATTERY_PRESENT Transitions 0 to 1 or 1 to 0
19
CHARGING_RESET_STATE = 1
CHGEN = 0
The Charger Is Not Charging
CHGEN = ~INHIBIT_CHARGE
The Charger Will Provide a Wake-Up Current When CHGEN = 1
CHGEN = ~INHIBIT_CHARGE
The Charger Will Provide Specified Charging Voltage and Current
When CHGEN = 1
A Zero Value for ChargingVoltage() Is Handled by Forcing CHGEN = 0
CHGEN = 0
The Charger Is Not Charging
20
CHARGING _WAKE-UP_STATE = 1
21
CHARGING_CONTROLLED_STATE = 1
