UPD166033T1U(1)-E1-AY

Overview

The UPD166033T1U(1)-E1-AY is an intelligent power device (IPD) manufactured by Renesas Electronics Corporation, designed for high-side power distribution applications. It features a single output channel with a maximum on-state resistance of 12 mΩ and operates within a supply voltage range of 4.5 V to 28 V. The component supports a maximum operating temperature of +150 °C and is housed in a TO-252-7 surface-mount package. Key timing specifications include a maximum turn-on time and standby time of 200 µs each. This device integrates robust protection mechanisms suitable for automotive and industrial environments.

Feature Summary

• Integrates built-in charge pump circuitry for efficient high-side switching operation without external bootstrap components.
• Provides embedded protection functions including current limitation and over-temperature shutdown to prevent device destruction.
• Features low on-state resistance to minimize power loss and thermal generation during conduction.
• Supports linear solenoid driving capabilities through integrated differential amplifier functionality.

Applications

• High-side power distribution in automotive electronic control units
• Linear solenoid driver circuits requiring precise current monitoring
• Industrial power management modules needing high-temperature reliability

Procurement Notes

Verify the exact part number suffix against official Renesas documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Check for any recent product change notices or end-of-life announcements that may affect long-term availability. Ensure compatibility with existing PCB footprint and thermal management design constraints.

Selection Notes

Select this IPD when a single-channel high-side switch with integrated diagnostics and protection is required. Consider the 12 mΩ on-resistance for efficiency needs and the 150 °C junction temperature rating for harsh environments. Evaluate the TO-252-7 package size against board space limitations. Compare against other UPD166xx series variants if multiple channels or different resistance values are needed.

Part Context

This component belongs to the µPD166033 series of intelligent power devices from Renesas Electronics. These devices are part of a family designed for robust power switching in automotive and industrial applications. The series typically includes variants with different on-resistances, channel counts, and package options to suit diverse system requirements while maintaining standardized pinouts and protection features.

Replacement Considerations

Consult official Renesas cross-reference guides for verified substitute part numbers. Direct replacements must match the TO-252-7 package, single-channel configuration, and similar electrical characteristics. Verify that any alternative maintains equivalent protection thresholds and thermal performance ratings.
