Not used.
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 MAX17435/MAX17535 include a timer to
terminate charging if the charger has not received a
ChargeVoltage() or ChargeCurrent() command within
140s (min). If a timeout occurs, both ChargeVoltage()
and ChargeCurrent() commands must be sent again to
reenable charging.
