MaxLinear | SP2525A-1EN-L/TR

Exar’s state of the art solutions provide high efficiency, low quiescent current, small size and the industry’s best price/performance ratio.

Many of Exar’s most advanced power management ICs are offered in thermally enhanced, lead-free DFN or QFN packages for the best blend of low thermal impedance and minimal circuit board area. 

Exar power management products can be used as stand alone solutions but are designed to be used together to create a complete power management system. This product group includes low drop out linear regulators (LDOs), DC to DC switching regulators, PWM controllers, charge pumps, and microprocessor supervisors.

The SP2525A device is an integrated high-side power switch ideal for self-powered and bus-powered Universal Serial Bus (USB) applications. 

The high-side switches are MOSFETs with 70mΩ RDS(ON), which meets USB voltage drop requirements for maximum transmission wire length. Multi-purpose open-drain fault flag output indicates over-current limiting, thermal shutdown, or under voltage lockout. 

Output current is typically limited to 0.85A below the 5A safety requirement, and the thermal shutdown function shuts the switch off to prevent damage under over current conditions. Guaranteed minimum output rise time limits inrush current during hot plug-in, minimizing EMI and preventing the voltage at the upstream port from dropping excessively.
