MP5991GLU-Z Description

Short technical summary and product information.

The MP5991GLU-Z from Monolithic Power Systems is a hot swap controller designed for robust power management in networking applications. This device supports a wide input voltage range from 4V to 16V and can deliver a maximum output current of 50A. It features an integrated switch and offers programmable functions such as auto-retry, current limit, fault timeout, and slew rate control.

 

Key electrical characteristics include a typical supply current of 2.3 mA and an RDS(ON) of 1 MΩ. The operating temperature range is from -40°C to 125°C (TJ), ensuring reliable performance in various environments. The controller includes essential features like fault timeout, latched fault protection, PMBus communication, thermal shutdown, and undervoltage lockout (UVLO).

 

This hot swap controller is available in a 32-VFQFN exposed pad package, designed for surface mounting. Its compact size and surface mount capability make it suitable for integration into space-constrained designs. The device also supports tape and reel packaging for automated assembly processes.
