PG2
IN8
IN
AGND
REG2 Power Ground. Connect PG1, PG2, PG3, PG4, and AGND together. Refer to the MAX8660 EV
kit data sheet for more information.
REG8 Input Power Connection. IN8 must be connected to IN.
Main Battery Input. This input provides power to the IC. Connect a 0.47μF ceramic capacitor from
IN to AGND.
Analog Ground. Connect PG1, PG2, PG3, PG4, and AGND together. Refer to the MAX8660 EV kit
data sheet for more information.
REG8 Always-On 3.3V LDO Output. REG8 is the first regulator that powers up in the
20
20
V8
MAX8660/MAX8661. REG8 is supplied from IN and supplies up to 30mA. V8 is internally pulled to
AGND through 1.5k ? during IN undervoltage or overvoltage lockout. Connect V8 to VCC_BBATT
on Marvell PXA3xx processors.
Low-Battery Detect Falling Input. The LBF threshold is 1.20V. Connect LBF to LBR for 50mV

LBF
hysteresis. Use a three-resistor voltage-divider for larger hysteresis. LBF sets the falling voltage at
which LBO goes low. See the Low-Battery Detector ( LBO , LBF, LBR) section for more information.
Low-Battery Detect Rising Input. The LBR threshold is 1.25V. Connect LBF to LBR for 50mV
22
22
LBR
hysteresis. Use a three-resistor voltage-divider for larger hysteresis. LBR sets the rising voltage at
which LBO goes high. See the Low-Battery Detector ( LBO , LBF, LBR) section for more
information.
Manual Reset Input. A low MR input causes RSO to go low and resets all serial programmed
23
23
MR
registers to their default values. See the Reset Output ( RSO ) and MR Input section for more
information.
24
24
RAMP
Ramp-Rate Input. Connect a resistor from RAMP to AGND to set the regulator ramp rates. See the
Ramp-Rate Control (RAMP) section for more information.
REG5 Enable Input. Drive EN5 high to turn on REG5. EN5 has hysteresis so an RC can be used to
25

EN5
implement manual sequencing with respect to other inputs. EN5 is typically driven by the SYS_EN
output of an Marvell PXA3xx processor.

PG3
LX3
PV3
REG3 Power Ground. Connect PG1, PG2, PG3, PG4, and AGND together. Refer to the MAX8660 EV
kit data sheet for more information.
REG3 Switching Node. Connect LX3 to the REG3 inductor. LX3 is high impedance when REG3 is
shut down.
REG3 Power Input. Connect a 4.7 μ F ceramic capacitor from PV3 to PG3. All PV pins and IN must
be connected together externally.
Open-Drain Reset Output. RSO typically connects to the nRESET input on an applications

29
RSO
processor. An output low from the MAX8660/MAX8661 RSO resets all serial programmed
registers to their default values and causes the processor to enter its reset state. See the Reset
Output ( RSO ) and MR Input section for more information.
REG3 Voltage Sense Input. Connect V3 directly to the REG3 output voltage. The output voltage is
30
30
V3
adjustable from 0.725V to 1.8V through the serial interface. V3 is internally pulled to AGND through
550 ? when REG3 is shut down. V3 connects to VCC_APPS on Marvell PXA3xx processors.
REG3 and REG4 Active-High Hardware Enable Input. Drive EN34 high to enable both REG3 and
REG4. Drive EN34 low to allow the serial interface to enable REG3 and REG4 independently.

EN34
EN34 has hysteresis so an RC can be used to implement manual sequencing with respect to
other inputs. EN34 is typically driven by the PWR_EN output of an Marvell PXA3xx processor. See
the REG3/REG4 Enable (EN34, EN3, EN4) section for more information.
