UPD166033T1U-E1-AY

Overview

The UPD166033T1U-E1-AY is a single-channel N-channel high-side intelligent power device (IPD) manufactured by Renesas Electronics. It operates within a supply voltage range of 4.5 V to 28 V and features a maximum on-state resistance of 12 mΩ. The component supports a maximum operating junction temperature of +150 °C and includes built-in protection mechanisms such as overcurrent detection shutdown and overtemperature protection. Packaged in a TO-252-7 surface-mount format, it integrates a charge pump circuit for efficient high-side switching control.

Feature Summary

• Integrates an N-channel MOSFET with a built-in charge pump circuit for high-side driving capability.
• Provides embedded safety features including current limitation, overtemperature protection, and ground failure protection.
• Offers diagnostic feedback through proportional load current sensing and defined fault signals during load anomalies.

Applications

• Automotive electronic/electrical architecture power distribution modules
• Solid-state power distribution units replacing traditional fuses or mechanical relays
• High-side switching applications requiring robust short-circuit and thermal protection

Procurement Notes

Verify the specific suffix E1-AY against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the TO-252-7 package dimensions align with your PCB footprint requirements. Cross-reference the part number with official Renesas distributors to confirm current availability and authenticity before finalizing procurement plans.

Selection Notes

Select this component when a single-channel high-side switch with integrated diagnostics is required. The 12 mΩ on-resistance suits moderate current loads while minimizing conduction losses. Consider the TO-252-7 package for thermal management needs and verify that the 4.5 V to 28 V input range matches your system's power supply specifications.
