LM5069
Overview
The LM5069 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 LM5069 provides in-rush current control to limit system voltage droop and transients.
- 1 Wide operating range: 9 V to 80 V
- 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 overcurrent events
- Internal high side charge pump and gate driver for external N-channel MOSFET
- Adjustable undervoltage lockout (UVLO) and 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
