SP2526A
SP2526A is Dual Channel USB Power Distribution Switch manufactured by Exar.
DESCRIPTION
The SP2526A device is a dual +3.0V to +5.5V USB Supervisory Power Control Switch ideal for self-powered and bus-powered Universal Serial Bus (USB) applications.
Each switch has low on-resistance (110mΩ typical) and can supply 500m A minimum. The fault currents are limited to 1.0A typical and the flag output pin for each switch is available to indicate fault conditions to the USB controller. The thermal shutdown feature will prevent damage to the device when subjected to excessive current loads. The undervoltage lockout feature will ensure that the device will remain off unless there is a valid input voltage present.
The SP2526A is offered in a Ro HS pliant “green”/halogen free 8-pin NSOIC package.
