APPLICATION INFORMATION
ON/OFF Control
The ON pin controls the state of the switch. Asserting ON high enables the switch. ON is active high and has a
low threshold, making it capable of interfacing with low-voltage signals. The ON pin is compatible with standard
GPIO logic threshold. It can be used with any microcontroller with 1.2-V, 1.8-V, 2.5-V or 3.3-V GPIOs.
Input Capacitor
To limit the voltage drop on the input supply caused by transient in-rush currents when the switch turns on into a
discharged load capacitor or short-circuit, a capacitor needs to be placed between V IN and GND. A 1- μ F ceramic
capacitor, C IN , placed close to the pins is usually sufficient. Higher values of C IN can be used to further reduce
the voltage drop.
Output Capacitor
Due to the integral body diode in the NMOS switch, a C IN greater than C L is highly recommended. A C L greater
than C IN can cause V OUT to exceed V IN when the system supply is removed. This could result in current flow
through the body diode from V OUT to V IN . A C IN to C L ratio of 10 to 1 is recommended for minimizing V IN dip
caused by inrush currents during startup.
Output Pulldown
The output pulldown is active when the user is turning off the main pass FET. The pulldown discharges the
output rail to approximately 10% of the rail, then the output pulldown is automatically disconnected to optimize
the shutdown current.
Board Layout
For best performance, all traces should be as short as possible. To be most effective, the input and output
capacitors should be placed close to the device to minimize the effects that parasitic trace inductances may have
on normal and short-circuit operation. Using wide traces for V IN , V OUT , and GND helps minimize the parasitic
electrical effects along with minimizing the case to ambient thermal impedance.
