QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 536

HOT SWAP CONTROLLER WITH MULTIFUNCTION CURRENT CONTROL

LTC4211

DESCRIPTION

Demonstration circuit DC536 is a Hot Swap controller

with multifunction current control featuring the

LTC4211. The DC536 is configured to operate with up to

7A as populated by the factory. Optional component

pads are provided for a higher power pass FET and

sense resistor for operation up to 20A.

The DC536 permits evaluating the LTC4211 during

turn-on and turn-off transients as well as during steady

state conditions.

OPERATING PRINCIPLES

The LTC4211 is a low voltage hot swap controller that

has a 2.5V to 16.5V operating range and a 17V absolute

maximum operating voltage for the Vcc pin. This demo

circuit is populated for +5V operation, but it can easily

be re-adjusted for any voltage between 2.5V to 16.5V by

replacing R3 and R1 (top resistors in the feedback di-

vider and the ON pin signal divider). There are two as-

sembly options for load current. The DC536 as supplied

by the factory is populated with an Si4410 MOSFET in an

SO-8 package and a 7mΩ current sense resistor provid-

ing a minimum 5A load current. The DC536 has provi-

sion for an FDB8030L MOSFET in the DD package which

when used with a 2.5mΩ sense resistor provides a

minimum16A load current.
