PI3PD22920GBEX

Overview

The PI3PD22920GBEX is a low-side power load switch manufactured by Diodes Incorporated, designed for power distribution applications. It features an integrated N-channel MOSFET capable of handling up to 4 A output current with an ultra-low on-resistance. The device operates within a supply voltage range of 750 mV to 3.6 V and supports controlled turn-on timing with a maximum run time of 970 µs and idle time of 3 µs. It functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in an 8-CSP package measuring 1.95x0.95 mm, suitable for surface-mount installation.

Feature Summary

• Integrates an N-channel MOSFET for efficient power switching with ultra-low on-resistance characteristics.
• Provides controlled turn-on functionality to manage inrush current during activation.
• Supports low-voltage operation starting from 750 mV for compatibility with various power rails.

Applications

• Power distribution circuits requiring compact load switching solutions
• Portable electronic devices utilizing low-voltage power management
• System-level power sequencing and protection interfaces

Procurement Notes

Verify the obsolete status of this component before integration into new designs, as manufacturers may discontinue production. Confirm availability through authorized distributors or secondary markets if immediate procurement is required. Ensure that the 8-CSP package dimensions align with existing PCB footprints. Check RoHS compliance documentation for environmental regulations relevant to the target market. Validate electrical parameters against specific application requirements prior to finalizing the bill of materials.

Selection Notes

Select this component when a small form factor is critical due to its 8-CSP packaging. Consider the 4 A current rating and low on-resistance for efficient power delivery in space-constrained designs. Evaluate the controlled turn-on feature if inrush current management is necessary. Ensure the input voltage range of 750 mV to 3.6 V matches the system power rail. Verify thermal performance within the specified -40°C to +85°C operating temperature range.
