S-816A42AMC-BART2U

Overview

The S-816A42AMC-BART2U 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 0.35 µA at VDD = 2.0 V, ensuring minimal power drain in battery-operated devices. The device offers a fixed output delay time of 200 ms (typical) and supports multiple output polarities. It operates within a wide voltage range of 1.0 V to 5.5 V and includes a built-in hysteresis function to prevent output fluctuations during voltage transitions.

Feature Summary

• Ultra-low current consumption for extended battery life
• Built-in hysteresis function prevents output chattering
• Fixed output delay time ensures stable reset generation
• Wide operating voltage range suitable for various logic families

Applications

• Battery-powered portable electronic devices
• Microcontroller system reset circuits
• Voltage monitoring in embedded systems
• Power management units requiring low standby current

Procurement Notes

Verify the specific suffix 'BART2U' corresponds to the required tape-and-reel packaging and output polarity configuration. Confirm the detection voltage matches the application requirement, as this model specifies a fixed threshold. Ensure compatibility with the target system's logic levels and operating temperature range before finalizing procurement.

Selection Notes

Select this component when ultra-low quiescent current is critical for battery efficiency. Verify that the fixed output delay meets the system's startup timing requirements. Consider the available package options and whether the integrated hysteresis eliminates the need for external components in noise-sensitive environments.

Part Context

This part belongs to the S-816 series of voltage detectors from ABLIC Inc., known for high precision and low power consumption. The series is widely used in consumer electronics and industrial applications where reliable voltage supervision is essential. The specific model indicates a particular detection voltage and packaging variant within this established product line.

Replacement Considerations

Check for direct pin-compatible alternatives from ABLIC or other manufacturers offering similar detection voltages and current specs. Ensure substitute parts maintain the same output delay characteristics and hysteresis values to avoid redesigning the reset circuitry.
