DESCRIPTION
The APE8935 is a small, ultra-low RON load switch
with controlled turn on. It contains one N-channel
MOSFET that can operate over an input voltage
range of 0.8V to 5.5V and support maximum
continuous current up to 6A. The switch is controlled
by an on/off input (EN), which is capable of
interfacing directly with low-voltage control signals.
Additional features include a 330Ω on-chip load
resistor is added for output quick discharge when
switch is turned off.
The APE8935 is available in 8-pin DFN 3x3-8L
package with smallest components.

APPLICATION INFORMATION
On/Off Control
The load switch is controlled by the EN pin. The EN pin is active high and has a low threshold making it
capable of interfacing with low voltage signals. The EN pin can be used with standard 1.5V, 1.8V, 2.5V or 3.3V
GPIO logic threshold. Do not leave the EN pin float.
Input Capacitor
An input capacitor is recommended to be placed between VIN and GND to limit the voltage drop on the input
supply during high current application.
Output Capacitor
Setting a CIN greater than the COUT is highly recommended. Since the internal body diode is in the NMOS
switch, this prevents the current flows through the body diode from VOUT to VIN when the system supply is
removed.
Layout Considerations
Follow the below guidelines for PCB layout to achieve stable operation. Take below figure for reference.
1. Keep the high current paths (VIN, VOUT and GND) wide and short to obtain the best effect.
2. The input and output capacitors should be close to the device as possible to minimize the parasitic trace
inductances.
3. Place the thermal vias under the exposed pad. This help for thermal diffusion away from the device.
