LTC1759
The Charger Controller Block
The LTC1759 charger operations are handled by the
charger controller block. This block is capable of charging
the selected battery autonomously or under host control.
The charger controller can request communications with
the system management host (SMHost) by asserting
INTB = 0; this will cause the SMHost, if present, to poll the
LTC1759.
The charger controller receives SMBus slave commands
from the SMBus controller block.
The charge controller allows the LTC1759 to meet the
following Smart Battery-controlled (Level 2) charger
requirements:
1. Implements the Smart Battery’s critical warning mes-
sages over the SMBus.
2. Operates as an SMBus slave device that responds to
ChargingVoltage() and ChargingCurrent() commands
and adjusts the charger output characteristics
accordingly.
OPERATIOU
The charger controller allows the LTC1759 to meet the
following host-controlled (Level 3) Smart Battery charger
requirements.
1. In a host-controlled system the host is able to operate
as an SMBus master device.
2. The host may determine the appropriate charging algo-
rithm by querying the battery or providing an alternative
special charging algorithm.
3. The host may control charging by disabling the Smart
Battery’s ability to transmit ChargingCurrent() and
ChargingVoltage() request functions and broadcasting
the charging commands to the LTC1759 over the SMBus.
4. The LTC1759 will still respond to Smart Battery critical
warning messages without host intervention.
The charger controller block uses the state machine of
Figure 3. The functional features for state transitions and
general control are detailed in Table 3.
