NCT3527U TR

Overview

The NCT3527U TR is an adjustable current-limited power distribution switch manufactured by Nuvoton Technology Corporation. It features a high-side N-channel output with a maximum load current of 2.5A and an on-resistance of 70mΩ. The device operates within a supply voltage range of 3.0V to 5.5V. Protection mechanisms include over-temperature shutdown, under-voltage lockout (UVLO), and adjustable fixed current limiting via an external resistor. The component is available in a SOT-23-5 surface-mount package.

Feature Summary

Adjustable current limiting capability controlled by an external resistor
Integrated thermal shutdown protection for overload safety
High-side switching configuration with low on-resistance

Applications

Power distribution in portable electronic devices
Load switching for USB peripheral hubs
Battery-powered IoT system power management

Procurement Notes

Verify the specific suffix designation to confirm operational mode. The standard NCT3527U variant utilizes latch-off protection upon fault detection, requiring system reset to recover. The NCT3527U-A variant employs auto-retry functionality, resuming operation after a delay period. Ensure the selected part number aligns with the required fault recovery strategy for the target application design.

Selection Notes

Select this component when adjustable current thresholds are required rather than fixed limits. The external resistor allows customization of the trip point to match specific load requirements. Consider the NCT3527U-A if automatic recovery from transient faults is necessary without manual intervention. Verify that the 70mΩ on-resistance meets the efficiency and thermal dissipation constraints of the high-side switch application.

Part Context

The NCT3527U belongs to the NCT352x series of high-side power switches designed for robust load protection. Unlike fixed-limit counterparts, this model offers flexibility through external programming of the current limit. It complements other Nuvoton PMIC solutions by providing precise control over power delivery paths in compact form factors suitable for space-constrained consumer electronics.
