... The CM3202-02 supports Suspend-To-RAM (STR) and ACPI compliance with Shutdown Mode which tri- states VTT to minimize quiescent system current. The CM3202-02 is available in a space saving TDFN-8 and SOIC-8 surface mount packages. Low thermal resistance allows them to withstand high power dissipation at 85°C ambient. The CM3202-02 can operate over the industrial ambient temperature range of – ...
