Maxim Integrated MAX5959LECS
- Part Number:
- MAX5959LECS
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3257381-MAX5959LECS
- Description:
- IC CTRLR HOT-PLUG QD 80-TQFP
- Datasheet:
- MAX5959LECS
Description
The MAX5959/MAX5960 are quad hot-plug controllers designed for PCI Express (PCle) applications. They provide hot-plug control for the main 12V, 3.3V, and 3.3V auxiliary supplies of four PCle slots. The MAX5959/MAX5960s' logic inputs/outputs allow interfacing directly with the system hot-plug management controller or through an SMBus with an external I/O expander such as the MAX7313. An integrated debounced attention switch and present-detect signals simplify system design.
Features
Hot Swap 12V, 3.3V, and 3.3V Auxiliary for 4 PCle Slots
Integrated Power MOSFETs for Auxiliary Supply Rails
Controls di/dt and dV/dt
Active Current Limiting Protects Against Overcurrent/Short-Circuit Conditions
Programmable Current-Limit Timeout
PWRGD Signal Outputs with Programmable Power-On Reset (POR) (160ms Default)
Latched FAULT Signal Output After Overcurrent or Overtemperature Fault
Attention Switch Inputs/Outputs with 4ms Debounce
Present-Detect Inputs
Force-On Inputs Facilitate Testing/Debug
Thermal Shutdown
Allow Control Through SMBus with an I/O Expander
