AAT4292中文资料Seven Channel High-Side I/O Expander数据手册Skyworks规格书

描述 Description

The AAT4292 SmartSwitch™ is a member of AnalogicTech’s Application Specific Power MOSFET™ (ASPM™) product family. The AAT4292 has seven P-channel MOSFETs configured for use as a high side microprocessor GPIO expander powered from a common supply source. Operating over a 1.8V to 5.5V range, the AAT4292 is ideal for portable Li-Ion/Polymer powered products. The state of each output channel is controlled with a single GPIO line via the EN/SET pin using AnalogicTech’s Simple Serial Control™ (AS²Cwire™) interface.
The switch states are controlled by AnalogicTech’s Simple Serial Control (AS²Cwire) interface which permits ease of control and efficiency of size. The quiescent supply current is very low, typically 6.3μA. In shutdown mode, the supply current is reduced to less than 1μA.
The AAT4292 is offered in a Pb-free, 10-pin SC70JW package specified over the -40°C to +85°C temperature range.
