UPD166032T1U-E1-AY

Overview

The UPD166032T1U-E1-AY is a single-channel N-channel high-side intelligent power device (IPD) from Renesas Electronics. It integrates a charge pump, voltage-controlled input, and proportional load current sensing for diagnostic feedback. The component features embedded protection mechanisms including short-circuit protection, overcurrent detection shutdown, overload detection with power limiting, absolute temperature cutoff, undervoltage lockout, and ground failure protection. It operates within a supply voltage range of 4.5 V to 28 V and supports an operating temperature range from -40 °C to +150 °C. The typical on-resistance is 12 mΩ at 25 °C junction temperature. It is housed in a TO-252-7 package.

Feature Summary

• Integrates a built-in charge pump and voltage-controlled input for reliable high-side switching operation.
• Provides proportional load current sensing to enable precise diagnostic feedback and monitoring.
• Includes comprehensive protection functions such as short-circuit protection, overcurrent detection, and absolute temperature cutoff.

Applications
