S-1701A3331-M5T1G

Overview

The S-1701A3331-M5T1G is a voltage detector manufactured by ABLIC Inc., designed to monitor supply voltages and generate reset signals. It features an ultra-low current consumption of typically 200 nA, ensuring minimal impact on battery-operated systems. The device offers a fixed output delay time of 20 ms to prevent false triggering during power-up transients. It operates within a wide supply voltage range of 1.2 V to 5.5 V and provides an active-low output signal when the monitored voltage drops below the specified threshold.

Feature Summary

• Ultra-low current consumption for extended battery life in portable devices
• Fixed output delay time prevents erroneous resets during power transitions
• Active-low output signal configuration for direct interface with microcontrollers

Applications

• Battery-powered portable electronics requiring low standby current
• Microcontroller system reset circuits
• Voltage monitoring in embedded systems

Procurement Notes

Verify the specific suffix M5T1G corresponds to the desired tape-and-reel packaging and marking code. Confirm the operating temperature range matches your application requirements. Ensure the input voltage does not exceed the absolute maximum ratings to prevent device damage. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines.

Selection Notes

Select this component when a fixed delay time is sufficient for the system's power-up sequence. Consider the 200 nA typical current draw for critical power budgeting. Verify that the active-low output polarity aligns with the target microcontroller's reset input logic. Evaluate the 1.2 V minimum operating voltage against the lowest expected battery level.

Part Context

This part belongs to the S-1701 series of voltage detectors from ABLIC Inc. The series is characterized by high precision and low power consumption. The 'A' in the model number indicates a specific output type or accuracy class within the family. The '3331' denotes the specific detection voltage threshold.

Replacement Considerations

Check for pin-compatible alternatives from other manufacturers offering similar 200 nA current consumption and 20 ms delay times. Verify that substitute parts support the same 1.2 V to 5.5 V input range. Ensure the replacement maintains the active-low output configuration.
