• Manufacturer Part Number: MAX1586AEVCMAXQU
• Description: Power Management IC Development Tools MAX1586A Evaluation Kit/Evaluation System
• Manufacturer: Maxim Integrated
• Series: MAX1586A, MAX1586B, MAX1586C, MAX1587A, MAX1587Cr

The SMBus dialog boxes accept numeric data in bina-
ry, decimal, or hexadecimal form. Hexadecimal num-
bers should be prefixed by $ or 0x. Binary numbers
must be exactly eight digits. See Figure 2 for an exam-
ple of this tool.
Note: In places where the slave address asks for an
8-bit value, it must be the 7-bit slave address of the
MAX1586A as determined by SRAD with the last bit set
to 1 for a read operation or zero for a write. Refer to the
MAX1586A data sheet for a complete list of registers
and functions.
The MAX1586A EV kit is a fully assembled and tested
surface-mount PCB that evaluates the MAX1586A
PMIC. The MAX1586A integrates three high-perfor-
mance, 1MHz, synchronous step-down DC-DC power
supplies, three low-dropout regulators, and a battery
backup supply.
The power outputs consist of a 3.3V at 1.3A I/O
(VCC_I/O) step-down output, a 2.5V at 900mA memory
(VCC_MEM) step-down output, a software-adjustable
0.7V to 1.475V at 500mA core (VCC_CORE) step-down
output, a 1.3V at 35mA phase-locked loop (VCC_PLL)
LDO, a 1.1V at 40mA SRAM (VCC_SRAM) LDO, and a
software-adjustable 0 to 3.0V at 35mA (VCC_USIM)
LDO. An additional 30mA backup battery (VCC_BATT)
output is also available.
Power-management functions include a power-OK
(POK) output, a manual reset input, multiple output-
enable inputs, a sleep function, and a reset output.
Activate the manual reset input by pressing the switch
labeled SW1.
Power sequencing is also available through component
placeholders R1–R6 and C1–C6. See the Optional
Power-Sequencing Circuitry section in the document
for more details.

Address (JU9)
Table 2. Sleep Selection (JU7)
Jumper JU9 sets the MAX1586A slave address. The
default address is 0010 1000 (SRAD = GND). See
Table 1 for a complete list of addresses.
Jumper JU7 controls the sleep function of the
MAX1586A EV kit. Removing the shunt from JU7 allows
the sleep function to be controlled by an external signal
source connected to the
sleep shunt positions.
