LM5050MK-1/NOPB Description

Short technical summary and product information.

The Texas Instruments LM5050MK-1/NOPB is a high-side OR-ing FET controller, suitable for applications requiring redundant power supplies. This device operates with an input voltage ranging from 5V to 75V, with a minimum of 1V when a VBIAS is applied.

 

Key electrical specifications include a typical quiescent current of 0.4mA and a maximum current rating of 250A. It features a fast 50ns response time to current reversal and a 2A peak gate turnoff current. The controller supports external N-channel MOSFETs and includes a charge pump gate driver.

 

Packaged in a SOT-23-6 Thin (TSOT-23-6) surface-mount package, the LM5050MK-1/NOPB is designed for efficient power management. Its operating temperature range is -40°C to 125°C, making it suitable for various environmental conditions. The controller also provides reverse current blocking and reverse polarity protection, enhancing system reliability.
