1.2MHz, Low-Cost,
High-Performance Chargers
Setting Charge Voltage
The VCTL input adjusts the battery-output voltage,
V BATT , and determines the number of cells. For 3- and
4-cell applications, use the MAX17005B; for 2- and
3-cell applications, use the MAX17006B. Use the
MAX17015B to adjust the cell number and set the cell
voltage with a resistive voltage-divider from the output.
Based on the version of the part, the number of cells
and the level of VCTL should be set as in Table 1.
Table 1. Cell Configuration
There are two constraints in choosing R7 and R8. The
resistors cannot be too small since they discharge the
battery, and they cannot be too large because FB pin
consumes less than 1μA of input bias current. Pick R8
to be approximately 10k ? and then calculate R7.
FB regulation error (±0.5% max) and the tolerance of R7
and R8 both contribute to the error on the battery volt-
age. Use 0.1% feedback resistors for best accuracy.
Figure 3 shows the MAX17015B charge-voltage regula-
tion feedback network.

Setting Charge Current
The voltage at ISET determines the voltage across cur-
rent-sense resistor RS2. ISET can accept either analog
or digital inputs. The full-scale differential voltage
between CSIP and CSIN is 80mV (8A for RS2 = 10m ? )
for the analog input, and 60mV (6A for RS2 = 10m ? ) for
the digital PWM input.
When the MAX17005B/MAX17006B/MAX17015B power
up and the charger is ready, if there is no clock edge
The MAX17005B/MAX17006B support from 4.2V/cell to
4.4V/cell, whereas the MAX17015B supports minimum
2.1V. The maximum voltage is determined with the
dropout performance of IC. When the required voltage
within 20ms, the circuit assumes ISET is an analog
input, and disables the PWM filter block. To configure
the charge current, force the voltage on ISET according
to the following equation:

for 3-cell selection of MAX17005B and MAX17006B,
4.2V > VCTL > 2.4V:
The input range for ISET is from 0 to V AA /2. To shut
down the charger, pull ISET below 26mV.
If there is a clock edge on ISET within 20ms, the PWM
filter is enabled and ISET accepts digital PWM input.
The PWM filter has a DAC with 8-bit resolution that cor-
responds to equivalent V CSIP-CSIN steps.
