TPS22961DNYT

Power Distribution Switches, Load Drivers Overview

The TPS22961DNYT is a single-channel load switch from Texas Instruments designed for power distribution applications. It operates within an input voltage range of 0.8 V to 3.5 V and supports a maximum continuous output current of 6 A. The device features an ultra-low on-resistance of 4.4 mΩ (maximum) and 6.5 mΩ (typical), minimizing power loss and heat generation. Key electrical parameters include a maximum turn-on time of 10 µs and a maximum turn-off time of 3.5 µs. It incorporates controlled slew rate functionality to limit inrush current during startup. The component is housed in an 8-pin WSON (DNY) surface-mount package, suitable for space-constrained designs.

Power Distribution Switches, Load Drivers Feature Summary

• Ultra-low on-resistance minimizes conduction losses and thermal impact
• Integrated output discharge capability ensures rapid voltage decay when disabled
• Controlled slew rate limits inrush current to protect upstream power sources
• Non-inverting logic control simplifies interface with system controllers

Power Distribution Switches, Load Drivers Applications

• Portable consumer electronics requiring efficient power management
• Peripheral power switching in mobile devices
• Battery-powered systems needing low quiescent current operation
• Industrial equipment with strict inrush current limitations

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix DNYT corresponds to the WSON-8 package and tape-and-reel or cut-tape packaging options as listed by authorized distributors. Confirm moisture sensitivity level (MSL) requirements for soldering processes. Ensure the operating temperature range (-40°C to +125°C junction) aligns with your system's thermal design constraints. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single-channel switch with high current capacity (6 A) and minimal voltage drop is required. The 3.5 V maximum input rating makes it suitable for 3.3 V and 5 V systems where the latter is operated within safe limits or stepped down. Consider the integrated discharge feature if fast shutdown times are critical. Compare against the TPS22962 series if higher voltage tolerance (up to 5.5 V) or lower resistance is needed, noting that the TPS22961 offers a balance of performance and cost for standard voltage rails.

Power Distribution Switches, Load Drivers Part Context

The TPS22961 belongs to Texas Instruments' TPS229xx family of load switches, which are designed for portable and battery-operated applications. This family emphasizes low on-resistance and small footprint solutions. The TPS22961 specifically targets applications requiring 6 A current handling with a 3.5 V input limit, distinguishing it from higher-voltage variants like the TPS22962. It complements other power management ICs in TI's portfolio for complete system power sequencing and protection.

Power Distribution Switches, Load Drivers Replacement Considerations

The TPS22962DNYT is a pin-compatible alternative offering a higher input voltage range up to 5.5 V and lower on-resistance (5 mΩ max). However, verify that the 3.5 V limit of the TPS22961 is sufficient for your supply rail. Other family members like TPS22961DSGT share similar electrical characteristics but differ in package type (DSGT vs DNY). Ensure any substitute matches the WSON-8 footprint and electrical ratings precisely.
