TMUX7213PWR

Overview

The TMUX7213PWR is a four-channel, low on-resistance (RON), precision analog switch featuring latch-up immunity and 1.8-V logic compatibility. It supports bidirectional signal flow across source and drain pins ranging from VSS to VDD. The device operates with a single supply voltage between 4.5 V and 44 V, or dual supplies from ±4.5 V to ±22 V. It provides an on-resistance of 2 Ω at 25°C, with a maximum continuous current of 220 mA in the TSSOP package. The component includes integrated pull-down resistors on logic pins for fail-safe operation and functions within an ambient temperature range of -40°C to +125°C.

Feature Summary

• Latch-up immune design prevents high-current parasitic events during overvoltage conditions.
• Integrated pull-down resistors on logic control inputs ensure fail-safe operation.
• Supports rail-to-rail bidirectional analog and digital signal transmission.

Applications

• EV charging station power modules
• Advanced driver assistance systems (ADAS)
• Automotive gateway and head unit applications

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm the exact package type and tape-and-reel specifications. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Cross-reference the manufacturer part number with the latest datasheet revision history to confirm compliance with current manufacturing standards.

Selection Notes

Select the TMUX7213PWR when both logic high and logic low control states are required for independent channel switching. This variant differs from the TMUX7211 and TMUX7212 by supporting full logic level compatibility. Evaluate the thermal dissipation requirements based on the TSSOP-16 package limitations and the expected continuous current load under the target operating temperature conditions.

Part Context

The TMUX7213PWR belongs to the TMUX721x family of precision switches manufactured by Texas Instruments. It shares the same core architecture as the TMUX7211 and TMUX7212 but is distinguished by its logic input configuration. All variants in this series offer identical electrical performance regarding on-resistance, leakage, and voltage ratings, differing only in how the SELx pins interpret logic levels.

Replacement Considerations

The TMUX7211PWR and TMUX7212PWR are direct functional substitutes within the same package. The TMUX7211 requires logic low to activate channels, while the TMUX7212 requires logic high. Verify that the system logic interface matches the replacement part's activation requirement before swapping.

FAQ

What distinguishes the TMUX7213 from the TMUX7211?

The TMUX7213 supports both logic high and logic low inputs to turn on the switches, whereas the TMUX7211 requires a logic low signal to activate the channels.

Does the TMUX7213PWR support asymmetric supply voltages?

Yes, the device supports asymmetric supplies, such as VDD = 12V and VSS = –5V, provided the differential voltage remains within the specified operating range.

How does the device handle overvoltage events?

The TMUX7213 features latch-up immunity, which prevents undesirable high-current events between parasitic structures typically caused by overvoltage conditions.
