AX8701
AX8701 is Power Multiplexer manufactured by AXElite.
DESCRIPTION
The AX8701 is a current limited power multiplexer acting as a high side switch for USB applications where heavy capacitive loads and short-circuits is likely to be encountered. It switches output voltage to 5VSB at S3/S4/S5 states with 200mΩ switch and 500m A capacity; to 5VCC at S0/S1/S2 states with 80mΩ switch and 1.5A capacity.
This device features an active-high enable control input. Soft start function limits the inrush current from supply input when enabled. Disabling the device reduces its standby current down to less than 1u A.
Optimal switch logic according to S3# and 5VCC status ensures seamless output voltage transition.
When the output load exceeds the current-limit threshold or a short is present, the AX8701 asserts overcurrent protection and limits the output current to a safe level by driving the power switches into saturation mode.
Other features include soft-start to limit inrush current during...
