Hot Swap Controller

FEATURES

DESCRIPTION

TheLTC^®4218isaHotSwap™controllerthatallowsaboard

to be safely inserted and removed from a live backplane.

An internal high side switch driver controls the gate of an

externalN-channelMOSFETforsupplyvoltagesfrom2.9V

to 26.5V. A dedicated 12V version (LTC4218-12) contains

preset12Vspeciﬁcthresholds,whilethestandardLTC4218

allows adjustable thresholds.

■

Wide Operating Voltage Range: 2.9V to 26.5V

■

Adjustable, 5% Accurate (15mV) Current Limit

■

Current Monitor Output

Adjustable Current Limit Timer Before Fault

Powergood and Fault Outputs

Adjustable Inrush Current Control

2% Accurate Undervoltage and Overvoltage

Protection

■

The LTC4218 provides an accurate (5%) current limit with

current foldback limiting. The current limit threshold can

be adjusted dynamically using an external pin. Additional

features include a current monitor output that ampliﬁes

the sense voltage for ground referenced current sensing.

Overvoltage, undervoltage and powergood monitoring

are also provided.
