hysteresis
• Adjustable overvoltage 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
• 10-Pin VSSOP packag
Applications
• Server backplane systems
• Base station power distribution systems
• Solid state circuit breaker
• 24-V and 48-V Industrial systems
Description
The ZCC5069 positive 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 ZCC5069 provides  in-rush current control to limit system voltage droop and transients. The current  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 1.25 V of the input voltage. The input undervoltage and  overvoltage lockout levels and hysteresis are programmable, as well as the initial insertion delay  time  and  fault  detection  time.
The ZCC5069-1  latches  off  after a fault detection,
while the  ZCC5069-2 automatically restarts at a fixed duty cycle. ZCC5069 is available in a 10-pin VSSOP
package.
