Rev 1.1 DIO7231 5.5V Low Loss Power Distribution Switch Features Descriptions Input voltage: 2.7V to 5.5V The DIO7231 power distribution switch is Typical 135m on-resistance intended for applications where precision current Under voltage lockout limiting is required or heavy capacitive loads and Over current protection, short circuit short circuits are encountered. The power switch protection and over temperature protection rising and falling times are controlled to minimize Fault time 5ms typically with blanking current surges during turning on/off. Reverse blocking (no body diode) No reverse current when power ON or power The DIO7231 provide 275mA current level. OFF Compact SOT23 packages The DIO7231 device limits the output current under a safe level by using a constant current mode when the output load exceeds the current Applications limit threshold. USB Ports/Hubs Digital TV The DIO7231 is available in the SOT23 package. It Set-Top Boxes is rated over the -40C to +85C temperature VOIP Phones range.
