High-Frequency,
Low-Cost SMBus Chargers
Reading IINP Voltage
To read the digital version of the IINP voltage, issue the
SMBus command IINPVoltage() command using the 16
bit data format listed in Table 8. The command code for
IINPVoltage() is 0x3E (0b00111110). The IINPVoltage()
command uses the read-word protocol (see Figure 3).
Charger Timeout
The MAX17035/MAX17435/MAX17535 include a timer
to terminate charging if the charger has not received a
ChargeVoltage() or ChargeCurrent() command within
175s. If a timeout occurs, both ChargeVoltage() and
ChargeCurrent() commands must be sent again to
reenable charging.
