Quick Start

Required Equipment

Before you begin, the following equipment is needed:

•

Maxim MAX6876EVCMOD2 (contains MAX6876 EV

kit board and CMOD232 module)

•

DC power supply, 9V DC at 200mA (included with

CMOD232 module)

•

Windows 98/2000/XP computer with an available

serial (COM) port

•

Standard 9-pin female-to-male straight-through seri-

al cable

•

DC power supplies capable of providing 0 to 5V for

up to four channels of sequenced and/or tracked

power through the MAX6876 EV system. (Power-

supply current requirements depend on user con-

figuration and application.)

•

Test leads with 0.175in banana plugs to connect

the MAX6876 EV kit board to power supplies

Procedure

Do not turn on any power supplies until all connec-

tions are completed:

1) Set JMP1 to the 2-3 position for normal UVLO oper-

ation. See Table 1. If JMP1 is set to the 1-2 position,

install appropriate resistors at R1 and R2 to set the

desired UVLO voltage.

2) Set JMP2 to the 1-2 position to enable voltage

tracking/sequencing. Leaving JMP2 open allows

remote hardware control of the ENABLE pin

through the CMOD232 module. See Table 2.

3) Ensure JMP3 is not shorted for normal operation

(non-MARGIN functionality). See Table 3.

4) Ensure that shorting links at JMP4 and JMP5 are

tion software.
