LTC4238

High Voltage High Current

Hot Swap Controller

FEATURES

DESCRIPTION

The LTC^®4238 is a high voltage high current Hot Swap

controller that allows a board to be safely inserted and

removed from a live backplane. Dual 12V gate drive is

well suited for high power applications to either share

safe operating area across parallel MOSFETs or support

a 2-stage start-up that first charges the load capacitance

followed by enabling a low on-resistance path to the load.

Allows Safe Board Insertion into Live Backplane

Wide Operating Voltage Range: 6.5V to 80V

Drives Two Gates for High Power Applications

Configurable Parallel, Staged Start or

Single MOSFET Modes

Adjustable Precision Current Limit: 6mV to 20mV

Current Foldback Limits MOSFET Power

SOA Timer Optimizes MOSFET Capability

The device features active current limiting (ACL) with two

foldback options as V increases. The constant power

profile limits the power dissipation to be no higher than

a fixed value, while the high power profile allows the part

to ride through large input steps during operation.

Monitors V and V for MOSFET Health

12V Gate Drive for Lower MOSFET R

DS(ON)

Parallelable Controllers for Very High Current Levels

Available in 24-Lead Narrow SSOP and 24-Pin

4mm × 5mm QFN Packages

The LTC4238 notifies when output power is good. In

addition, it has protection features that respond to input

undervoltage, overvoltage; and generate a fault when

there is an overcurrent or FET bad condition.
