Maxim Integrated MAX4773EUT T
- Part Number:
- MAX4773EUT T
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3251548-MAX4773EUT T
- Description:
- IC SWITCH 1X1 SOT23-6
- Datasheet:
- MAX4773EUT T
Description
The MAX4772/MAX4773 are analog switches with selectable internal current limiting to prevent damage to host devices due to faulty load conditions. They feature a logic input to select a guaranteed 200mA or 500mA current limit, making them ideal for SDIO and other load-switching applications. These switches have a low 0.20 on-resistance and operate from a 2.0V to 4.5V input voltage range. When the switch is on and a load is connected to the port, a guaranteed blanking time of 14ms ensures that the transient voltage settles down. If, after this blanking time, the load current is greater than the current limit, the MAX4772 switch is turned off and issues a FLAG to the microprocessor. The switch can be turned on again by cycling the power or the ON input. The MAX4773 has an autoretry feature where the switch turns off and issues a FLAG to the microprocessor after the blanking time and then continuously checks to see if the overload condition is present. The switch remains on after the overload condition disappears and FLAG deasserts.
