7 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification,

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

7.1 Application Information

The 2N7002L device can be used in level-translation applications for interfacing between devices or systems

that are operating at different interface voltages. In the below example, the System Controller drives the gate of

the 2N7002L. When the controller outputs a high logic level, the MOSFET turns on and pulls the EN pin of the

system device low. When the controller output is low, the MOSTFET turns off and the pull-up resistor brings the

EN pin high to 5V. This creates a open-drain style interface for level shifting or for driving enable signals at a

higher voltage than the controller's logic domain.

7.2.1 Design Requirements

For proper operation of the 2N7002L, the design must remain within the limits defined in the Absolute Maximum

Ratings and Electrical Characteristics tables.

7.2.2 Detailed Design Procedure

Designing with the 2N7002L requires selecting appropriate operating conditions for gate drive, load current,

and switching behavior while ensuring all parameters remain within the limits defined in the Absolute Maximum

Ratings and Electrical Characteristics tables.

1. Select the operating VDS: ensure the supply voltage applied to the drain does not exceed the abs max

ratings.

2. Choose a valid VGS: use a logic-level gate voltage that falls within the recommended VGS limits.

3. Confirm load current capability: make sure the drain current is within the device's continuous current and

thermal capabilities.

4. Check switching capabilities: verify that the gate-drive strength and switching frequency are compatible with

the device's gate charge and capacitances.
