LTC4100
OPERATION
Description of Supported Battery Charger Functions
The functions are described as follows (see Table 1 also):
FunctionName() ‘hnn (command code)
Description: A brief description of the function.
Purpose: The purpose of the function, and an example
where appropriate.
? SMBus Protocol: Refer to Section 5 of the Smart
Battery Charger specification for more details.
Input, Output or Input/Output: A description of the data
supplied to or returned by the function.
ChargerSpecInfo() (‘h11)
Description: The SMBus Host uses this command to read
the LTC4100’s extended status bits.
Purpose: Allows the System Host to determine the
specification revision the charger supports as well as
other extended status information.
? SMBus Protocol: Read Word.
Output: The CHARGER_SPEC indicates that the LTC4100
supports Version 1.1 of the Smart Battery Charger
Specification. The SELECTOR_SUPPORT indicates that
the LTC4100 does not support the optional Smart Battery
Selector Commands.
ChargerMode() (‘h12)
Description: The SMBus Host uses this command to set
the various charger modes. The default values are set to
allow a Smart Battery and the LTC4100 to work in concert
without requiring an SMBus Host.
Purpose: Allows the SMBus Host to configure the charger
and change the default modes. This is a write only function,
but the value of the “mode” bit, INHIBIT_CHARGE may be
determined using the ChargerStatus() function.
? SMBus Protocol: Write Word.
Input: The INHIBIT_CHARGE bit allows charging to be
inhibited without changing the ChargingCurrent() and
ChargingVoltage() values. The charging may be resumed
by clearing this bit. This bit is automatically cleared when
power is reapplied or when a battery is reinserted.
The ENABLE_POLLING bit is not supported by the LTC4100.
Values written to this bit are ignored.
The POR_RESET bit sets the LTC4100 to its power-on
default condition.
The RESET_TO_ZERO bit sets the ChargingCurrent()and
ChargingVoltage() values to zero. This function ALWAYS
clears the ChargingVoltage() and ChargingCurrent() values
to zero even if the INHIBIT_CHARGE bit is set.
ChargerStatus() (‘h13)
Description: The SMBus Host uses this command to read
the LTC4100’s status bits.
Purpose: Allows the SMBus Host to determine the status
and level of the LTC4100.
? SMBus Protocol: Read Word.
Output: The CHARGE_INHIBITED bit reflects the status
of the LTC4100 set by the INHIBIT_CHARGE bit in the
ChargerMode() function.
The POLLING_ENABLED, VOLTAGE_NOTREG, and
CURRENT_NOTREG are not supported by the LTC4100.
The LTC4100 always reports itself as a Level 2 Smart
Battery Charger.
CURRENT_OR bit is set only when ChargingCurrent()
is set to a value outside the current regulation range of
the LTC4100. This bit may be used in conjunction with
the INHIBIT_CHARGE bit of the ChargerMode() and
ChargingCurrent() to determine the current capability of
the LTC4100. When ChargingCurrent() is set to the I LIM
+ 1, the CURRENT_OR bit will be set.
VOLTAGE_OR bit is set only when ChargingVoltage()
is set to a value outside the voltage regulation range of
the LTC4100. This bit may be used in conjunction with
the INHIBIT_CHARGE bit of the ChargerMode() and
ChargingVoltage() to determine the voltage capability of
the LTC4100. When ChargingVoltage() is set to the V LIM ,
the VOLTAGE_OR bit will be set.
The RES_OR bit is set only when the SafetySignal resis-
tance value is greater than 95kΩ. This indicates that the
SafetySignal is to be considered as an open circuit.
