LM5069

Positive High Voltage Hot Swap / Inrush Current Controller

with Power Limiting

General Description

The LM5069 positive hot swap controller provides intelligent

Adjustable current limit

■

Circuit breaker function for severe over-current events

Internal high side charge pump and gate driver for external

N-channel MOSFET

Adjustable under-voltage lockout (UVLO) and hysteresis

Adjustable over-voltage lockout (OVLO) and hysteresis

control of the power supply connections during insertion and

removal of circuit cards from a live system backplane or other

"hot" power sources. The LM5069 provides in-rush current

control to limit system voltage droop and transients. The cur-

rent limit and power dissipation in the external series pass N-

Channel MOSFET are programmable, ensuring operation

within the Safe Operating Area (SOA). The POWER GOOD

output indicates when the output voltage is within 1.25V of the

input voltage. The input under-voltage and over-voltage lock-

out levels and hysteresis are programmable, as well as the

initial insertion delay time and fault detection time. The

■

Initial insertion timer allows ringing and transients to

subside after system connection

Programmable fault timer avoids nuisance trips

Active high open drain POWER GOOD output

Available in latched fault and automatic restart versions

■

LM5069-1 latches off after a fault detection, while the Applications

LM5069-2 automatically restarts at a fixed duty cycle. The

LM5069 is available in a 10 pin MSOP package.
