SP2526A-2EN-L/TR 电源开关IC

SP2526A-2EN-L/TR

Dual Channel USB Power Distribution Switch

GENERAL DESCRIPTION

The SP2526A-2EN-L/TR 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 500mA 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.
