MAX4628EUT-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4628EUT-T is a low-on-resistance, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +1.8V to +5.5V single supply and features normally open contacts with two control inputs. The device provides fast switching speeds with a maximum turn-on time of 50ns and a maximum turn-off time of 30ns at +5V. It includes overcurrent protection to prevent damage from short circuits. Packaged in a SOT23-6 format, it supports continuous currents up to ±400mA.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Features integrated overcurrent protection circuitry that activates when the voltage drop across the switch reaches approximately 0.6V, providing current-limiting and thermal-shutdown capabilities to protect against sustained overloads and direct short circuits.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component designation matches the specific ordering code for the MAX4628 variant. Confirm the package type corresponds to the six-pin configuration required for the dual-input control logic. Ensure the temperature range meets the operational requirements of the target environment before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally open SPST switch with dual control inputs is required. It is suitable for applications needing low on-resistance and high-speed switching within a single-supply voltage range. Consider the SOT23-6 footprint constraints and the specific logic input compatibility for the system design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4626/MAX4627/MAX4628 family of low-voltage analog switches. While the MAX4626 and MAX4627 are pin-compatible with older industry-standard devices like the MAX4514 and MAX4515 respectively, the MAX4628 utilizes a distinct six-pin layout to accommodate its additional inverted digital control input.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4626 is explicitly noted as pin compatible with the MAX4514, and the MAX4627 is pin compatible with the MAX4515. Direct substitution for the MAX4628 requires verifying the availability of a component with matching dual-control input functionality and the SOT23-6 package.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the overcurrent protection mechanism function?

The internal circuitry activates when the voltage drop across the on-switch reaches 0.6V. For sustained overcurrent conditions, the switch turns off; if the overload persists, it cycles off and on to produce a pulsed output.

What is the maximum continuous current rating?

The continuous current rating from NO/NC to COM is ±400mA.

Can the logic inputs be driven above the supply voltage?

Yes, the logic inputs can be driven up to +5.5V regardless of the supply voltage, allowing compatibility with higher voltage logic levels even when operating at lower supply voltages.
