MP4835AGRD-T

Overview

The MP4835AGRD-T is a high-voltage analog switch featuring 32 single-pole, single-throw (SPST) channels. It operates with an on-state resistance of 24 ohms and includes integrated output bleed resistors for signal discharge. The device supports operating supply voltages of 3.3 V and 5 V, with a power dissipation rating of 6.7 W. It is housed in a 72-VFQFN package suitable for surface mount installation. The component functions within a temperature range of -25°C to +125°C, ensuring reliability in demanding environments.

Feature Summary

Integrates 32 SPST analog switches with high-voltage capability
Includes built-in output bleed resistors for rapid signal discharge
Supports standard 3.3 V and 5 V logic supply levels
Rated for extended industrial temperature operation up to 125°C

Applications

High-density data acquisition systems requiring multiple channel switching
Signal routing in test and measurement instrumentation
Industrial control panels with extensive sensor inputs
Medical equipment signal multiplexing applications

Procurement Notes

Verify the specific suffix GRD-T against official Monolithic Power Systems documentation to confirm pinout compatibility and thermal performance specifications. Ensure that the 72-VFQFN footprint matches the target PCB design constraints. Confirm that the 24-ohm on-resistance meets the signal integrity requirements of the intended application circuit before finalizing procurement orders.

Selection Notes

Select this component when a high-channel-count analog switch is required for signal routing. The integrated bleed resistors simplify circuit design by eliminating external discharge components. Consider the 6.7 W power dissipation limit when designing thermal management solutions for dense layouts. Verify that the 3.3 V or 5 V supply voltage aligns with the system's available power rails.

Part Context

This part belongs to the MP4835A family of analog switches from Monolithic Power Systems. The series is designed for applications requiring multiple independent signal paths within a compact form factor. The MP4835AGRD-T variant specifically denotes the tape-and-reel packaging configuration and the 72-VFQFN package type, distinguishing it from other package options within the same functional family.

Replacement Considerations

Consult official MPS substitution guides for direct equivalents. Verify pin-to-pin compatibility and electrical parameters such as on-resistance and leakage current. Ensure that any substitute part maintains the 32-channel count and high-voltage specifications required by the original design.

FAQ

What is the function of the integrated output bleed resistors?

The integrated bleed resistors provide a path for discharging stored charge at the output nodes, ensuring rapid signal settling and preventing floating states.
