Pinout
The MAX4840AELT+T is a power switch device. It features a total of 6 pins. Here’s a concise breakdown of its pin functions:
1. IN: This is the supply voltage input pin. It connects to the source voltage that you want to manage or control.
2. OUT: This pin is the output of the switch. When the device is enabled, the voltage present at the IN pin is passed through to the OUT pin.
3. EN: This is the enable pin. A high signal on this pin enables the switch, allowing current to flow from IN to OUT. Conversely, a low signal disables the switch.
4. GND: This is the ground pin. It must be connected to the system ground.
5. SET: This pin is used to set the current limit. It allows for configuration of the maximum current that can pass through the switch, providing overcurrent protection.
6. FLAG: This is an output pin that signals fault conditions. It goes low to indicate an overcurrent, overtemperature, or other fault condition.
