GENERAL 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 (110m ?
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.
The SP2526A is offered in a RoHS compliant
“green”/halogen free 8-pin NSOIC package.
Rev. 2.1.0
