MAX5900NNEUT+T

The MAX5900NNEUT+T is a -100V, simple swapper hot swap controller in 6 pin SOT-23 package. It allows a circuit card to be safely hot plugged into a live backplane without causing a glitch on the power supply rail. This device operates from -9V to -100V and provides the simplest hot swap solution by eliminating all external components except an external N-channel MOSFET. The MAX5900 includes an undervoltage lockout (UVLO) function, ON/OFF control input and a power good status output. Typical applications include telecom line cards, network routers, base station line cards, network switches and servers.

• Active-low power good logic
• Built-in thermal shutdown feature is also included to protect external MOSFET in case of overheating
• Default UVLO is -31.5V
• Requires no external sense resistor
• Drives external N-channel MOSFET, limits inrush current
• Less than 1mA quiescent current
• ON/active-low OFF input permits load power supply control and sequencing
• Adjustable undervoltage lockout, power good output with 100V rating
• Operating temperature range from -40°C to +85°C
