MAX7500 Evaluation Kit
Detailed Description of Hardware
The MAX7500 evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount PCB that evaluates the
MAX7500 digital temperature sensor. The MAX7500
accurately measures temperature, provides an
overtemperature alarm/interrupt/shutdown output, fea-
tures three address select lines, and integrates a time-
out feature that offers protection against I 2 C bus
lockups.
The EV kit is self-powered from the on-board USB inter-
face and requires no external power. The MAX7500 EV
kit can also evaluate the MAX7501 –MAX7504 ICs.
Request free IC samples from the factory when order-
ing the MAX7500 EV kit.
The MAX7500 EV kit provides an on-board I 2 C/SMBus
interface and is connected to the computer through the
USB port. The EV kit includes Windows 2000/XP and
Windows Vista-compatible software that provides a
graphical user interface (GUI) for control of the
MAX7500 ’s programmable features and selects
between the eight available slave addresses of the
MAX7500 IC.
Power-Supply Options
Jumper JU1 selects between the MAX7500 EV kit ’s
power-up options; either on-board through the USB
interface or through an external user-supplied DC power
supply. The voltage from the USB interface is stepped
down to +3.3V through the MAX8512 LDO. To configure
these options, set JU1 as desired (see Table 1).
