LM5067
Negative Hot Swap / Inrush Current Controller with Power
Limiting
General Description
The LM5067 negative hot swap controller provides intelligent
control of the power supply connections during insertion and
removal of circuit cards from a live system backplane or other
“hot” power sources. The LM5067 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). In addition, the
LM5067 provides circuit protection by monitoring for over-
current and over-voltage conditions. The POWER GOOD
output indicates when the output voltage is close to the input
voltage. The input under-voltage and over-voltage lockout
levels and hysteresis are programmable, as well as the fault
detection time. The LM5067-1 latches off after a fault detec-
tion, while the LM5067-2 automatically attempts restarts at a
fixed duty cycle. The LM5067 is available in a 10 pin MSOP
and a 10 pin LLP package.
Features
■ Wide operating range: -9V to -80V
■ In-rush current limit for safe board insertion into live power
sources
■ Programmable maximum power dissipation in the external
pass device
■ Adjustable current limit
■ Circuit breaker function for severe over-current events
■ Adjustable under-voltage lockout (UVLO) and hysteresis
■ Adjustable over-voltage lockout (OVLO) and hysteresis
■ 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
Applications
■ Server Backplane Systems
■ In-Rush Current Limiting
■ Solid State Circuit Breaker
■ Transient Voltage Protector
■ Solid State Relay
■ Under-voltage Lock-out
■ Power Good Detector/Indicator
Package
■ MSOP-10
