LTC4101
OPERATION
Controlled Charging Algorithm Overview
The following conditions must be met in order to allow
controlled charging to start on the LTC4101:
1. The ChargingVoltage() AND ChargingCurrent() function
must be written to non-zero values.
2. The SafetySignal must be RES_COLD, RES_IDEAL, or
RES_UR.
3. AC must be present. This is quali?ed by DCDIV > V ACP .
The following conditions will stop the Controlled Charging
Algorithm and will cause the Battery Charger Controller
to stop charging:
1. The ChargingCurrent() AND ChargingVoltage() func-
tions have not been written for T TIMEOUT .
2. The SafetySignal is registering RES_OR.
3. The SafetySignal is registering RES_HOT.
4. The AC power is no longer present. (DCDIV < V ACP )
5. ALARM_INHIBITED is set in the ChargerStatus()
function.
6. INHIBIT_CHARGE is set in the ChargerMode() function.
Clearing INHIBIT_CHARGE will cause the LTC4101 to
resume charging using the previous ChargingVoltage()
AND ChargingCurrent() function values.
7. RESET_TO_ZERO is set in the ChargerMode() function.
8. CHGEN pin is pulled low by an external device. The
LTC4101 will resume charging using the previous
ChargingVoltage() AND ChargingCurrent() function
values, if the CHGEN pin is released by the external
device.
9. Insuf?cient DCIN voltage to charge the battery. The
LTC4101 will resume charging using the previous
ChargingVoltage() AND ChargingCurrent() function
values, when there is suf?cient DCIN voltage to charge
the battery.
10. Writing a zero value to ChargingVoltage() function.
11. Writing a zero value to ChargingCurrent() function.
The SafetySignal Decoder Block
This block measures the resistance of the SafetySignal and
features high noise immunity at critical trip points. The low
power standby mode supports only battery presence SMB
charger reporting requirements when AC is not present.
The SafetySignal decoder is shown in Figure 4. The value
of R THA is 1.13k and R THB is 54.9k.
SafetySignal sensing is accomplished by a state machine
that recon?gures the switches of Figure 4 using THA_SELB
and THB_SELB, a selectable reference generator, and two
comparators. This circuit has two modes of operation
based upon whether AC is present.
