the battery is removed, the ChargingCurrent() register
returns to its power-on reset state.
ChargingVoltage() (POR: 0x4800)
The ChargingVoltage() command uses the write-word
protocol (Figure 3a). The command code for
ChargingVoltage() is 0x15 (0b00010101). The 16-bit
binary number formed by D15
–
D0 represents the volt-
age set point (V0) in millivolts; however, since the
MAX1645B has 16mV resolution in setting V0, the D0,
D1, D2, and D3 bits are ignored as shown in Table 5.
The ChargingVoltage() command is used to set the bat-
tery charging voltage compliance from 1.024V to
18.432V. All codes greater than or equal to 0b0100
1000 0000 0000 (18432mV) result in a voltage over-
range, limiting the charger voltage to 18.432V. All codes
below 0b0000 0100 0000 0000 (1024mV) terminate
charge. Figure 7 shows the mapping between V0
