... Rev 0; 8/97 P-Channel Switch with Thermal Shutdown _______________General Description The MAX869L P-channel load switch features an accu- rate user-set current limit and low on-resistance. This switch is designed to protect your power source from shorts and surges by limiting current and preventing the system supply from being pulled low. The input volt- age range is 2.7V to 5.5V. The MAX869L features a 2A, 45mΩ ...

... OUT _______________Detailed Description The MAX869L P-channel MOSFET power switch limits output current to a programmed level. When the output current passes through the main switch, a smaller cur- rent also passes through the replica switch (I and through R exceeds the trip voltage of 1.24V, the current-limit error ...

... R SET 1.24V Figure 2. Setting the Current Limit GND The MAX869L provides a fault output (FAULT). This open-drain output goes low when in current limit or when the die temperature exceeds 135°C. A 100kΩ pull-up resistor from FAULT to IN provides a logic- control signal. __________Applications Information To limit the input voltage drop during momentary output ≤ ...
