Description
LTC2936
Programming Board for Programmable Hex
Voltage Supervisor with EEPROM
The DC2450A programming board contains the cir-
cuitry needed to program and verify the EEPROM of the
LTC
®
2936
. This is its sole purpose. The LTC2936 comes
in either a 24-pin SSOP or a 24-pin QFN package. The
DC2450A-A supports the QFN and the DC2450A-B sup-
ports the SSOP package.
The LTpowerPlay™ GUI stores configuration settings into
the LTC2936 EEPROM. Download and install the software
from this location:

The DC2450A communicates with LTpowerPlay through
a Linear Technology
®
DC1613 USB to I
2
C/SMBus/PMBus
Controller.
What Can You Do with the DC2450A
1. Compare the contents of the device’s EEPROM against
any Project File. (Verify)
2. Reprogram the contents of the device’s EEPROM using
any Project File. (Program and Verify)
