SLG7NT4081V

Specialty Logic Overview

The SLG7NT4081V is a specialized power management IC functioning as a PWROK generator and startup latching circuit. It operates on a 3.3V supply voltage (range 3.0V to 3.6V) with a quiescent current of 1 µA. The device features four digital inputs and four outputs, including two push-pull and two open-drain configurations. Key electrical parameters include a high-level input voltage threshold of 1.8V, a low-level threshold of 1.1V, and a maximum output voltage of 2.1V for push-pull logic. It provides a startup time of 7 ms after VDD reaches 1.6V and a delay time of 10 ms. The component is housed in a 12-lead TDFN package measuring 2.5mm x 2.5mm.

Specialty Logic Feature Summary

• Integrates power good generation and startup latching functions within a single system-on-chip architecture.
• Provides flexible output configurations with both push-pull and open-drain logic levels.
• Designed for low-power applications with minimal quiescent current consumption.
• Supports digital input control for system power sequencing and shutdown management.

Specialty Logic Applications

• Power sequencing circuits for portable electronic devices

• Startup latch mechanisms for embedded systems

Specialty Logic Procurement Notes

Verify the specific package variant required, as the part is available in both tape-and-reel and cut-tape formats. Confirm that the design accommodates the 12-TDFN footprint dimensions. Ensure input voltage levels align with the specified logic thresholds before integration. Check for any RoHS compliance documentation requirements relevant to your manufacturing region.

Specialty Logic Selection Notes

Select this component when a dedicated power good generator and startup latch are needed in a compact package. It is suitable for designs requiring low quiescent current and precise timing delays. Consider the available input and output configurations to match the system's logic levels. Evaluate the thermal performance of the exposed pad if operating near temperature limits.

Specialty Logic Part Context

This device belongs to Renesas' GreenPAK family of programmable mixed-signal system-on-chips. These components are designed to replace multiple discrete logic and analog components, reducing board space and complexity. The SLG7NT4081V specifically targets power management applications where size and power efficiency are critical constraints.

Specialty Logic Replacement Considerations

No direct public substitute part numbers are documented in the provided datasheet. Designers should evaluate other GreenPAK series devices or dedicated PMICs from Renesas if pin compatibility is not required.
