TS880ICT

Overview

The TS880ICT is a single-channel analog comparator manufactured by STMicroelectronics, designed for ultra-low power applications. It features rail-to-rail input and output capabilities with an open-drain configuration. The device operates on a supply voltage range of 900 mV to 5.5 V, consuming only 250 nA of quiescent current. Key electrical specifications include a propagation delay of 2 µs, an input offset voltage of 5 mV, and an input bias current of 10 pA. It supports a maximum output sink current of 1.2 mA and offers a common-mode rejection ratio of 78 dB. The component is housed in a compact SC-70-5 package and functions reliably within a temperature range of -40°C to +125°C.

Feature Summary

• Ultra-low nanopower consumption suitable for battery-operated portable devices
• Rail-to-rail input and output capability for maximum dynamic range
• Open-drain output configuration allowing flexible interfacing
• Wide operating temperature range for industrial environments

Applications

• Portable consumer electronics requiring extended battery life
• Battery-powered sensor interfaces
• Low-voltage signal conditioning circuits
• General-purpose threshold detection in space-constrained designs

Procurement Notes

Verify the specific suffix 'ICT' corresponds to the SC-70-5 package and reel/cut-tape availability from authorized distributors. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Ensure design compatibility with the open-drain output requirement, which necessitates an external pull-up resistor for proper logic level translation. Validate that the 900 mV minimum supply voltage aligns with the target system's power architecture.

Selection Notes

Select the TS880ICT when minimizing static power consumption is critical, particularly for single-supply systems operating near 1 V. The open-drain output requires careful consideration of pull-up resistor values to balance speed and power dissipation. Compare against push-pull alternatives if direct drive capability without external components is required. Verify that the 2 µs propagation delay meets the timing requirements of the application, as faster comparators may consume more current.

Part Context

The TS880ICT belongs to the TS880x family of rail-to-rail nanopower comparators from STMicroelectronics. This series is engineered to minimize battery supply leakage, thereby enhancing the operational lifetime of portable equipment. Unlike the quad TS884IDT which features push-pull outputs and a 14-SOIC package, the TS880ICT provides a single channel in a smaller SC-70-5 footprint with an open-drain output, optimizing it for cost-sensitive and space-constrained low-power designs.
