NCP305LSQ16T1

Supervisors Overview

The NCP305LSQ16T1 is a supervisory circuit manufactured by onsemi, functioning as a voltage detector with a fixed threshold of 1.6V. It features an open-drain or open-collector output configuration and operates within a single channel architecture. The device is housed in a compact SC-82AB package, which corresponds to a four-terminal surface-mount footprint. Designed for power supply support applications, it provides undervoltage detection capabilities essential for system reset control in portable microprocessor-based environments.

Supervisors Feature Summary

• Fixed threshold voltage detection for precise monitoring
• Open-drain or open-collector output interface
• Compact surface-mount packaging for space-constrained designs

Supervisors Applications

• Portable microprocessor system reset control
• Power supply support circuits
• Undervoltage detection in battery-operated devices

Supervisors Procurement Notes

Verify the specific suffix 'T1' against official datasheets to confirm tape-and-reel packaging specifications. Ensure compatibility with the SC-82AB footprint dimensions during PCB layout. Confirm lead-free compliance status if required by assembly standards. Cross-reference the 1.6V threshold requirement with system voltage rails to ensure proper triggering levels are met.

Supervisors Selection Notes

Select this component when a fixed 1.6V undervoltage detection threshold is required for system supervision. The open-drain output allows for flexible logic level interfacing. Consider the SC-82AB package size constraints relative to available board space. Verify that the single-channel architecture meets the monitoring needs without requiring additional channels.

Supervisors Part Context

Part of the NCP304/NCP305 series of ultra-low current voltage detectors designed for extended battery life in portable systems. These second-generation devices feature highly accurate undervoltage detectors with hysteresis to prevent erratic reset operation. The series includes complementary output options, with the NCP305 variant specifically offering active low reset outputs suitable for various microprocessor architectures.

Supervisors Replacement Considerations

NCP305LSQ16T1G is a verified lead-free equivalent within the same product family.
