Figure 8 shows the mapping between V0 (the voltage-
regulation-loop set point) and the ChargingVoltage( )
data.
The power-on reset value for the ChargingVoltage( )
register is 0xFFF0; thus, the first time a MAX1647 is
powered on, the BATT voltage regulates to 16.368V
with V
REF
= 4.096V. Any time the BATTERY_PRESENT
status bit is clear, the ChargingVoltage( ) register
returns to its power-on reset state.
ChargingCurrent( )
The ChargingCurrent( ) command uses Write-Word
protocol. The command code for ChargingCurrent( ) is
0x14; thus, the CMD7–CMD0 bits in Write-Word proto-
col should be 0b00010100. The 16-bit binary number
formed by D15–D0 represents the current-limit set point
(I0) in milliamps. Tying SEL to AGND selects a 1.023A
maximum setting for I0. Leaving SEL open selects a
2.047A maximum setting for I0. Tying SEL to VL selects
a 4.095A maximum setting for I0.
