STMicroelectronics TS880ICT

Overview

TS880ICT from STMicroelectronics is a nanopower, rail-to-rail input, open-drain output comparator in SC70-5 package. It delivers 250 nA typical supply current, 2 µs typical propagation delay (at 100 mV overdrive, VCC = 1.2 V), and operates from 0.9 V to 5.5 V across –40 °C to +125 °C. It enables ultra-low-power voltage monitoring in battery-critical portable medical sensors.

For engineers reviewing the TS880ICT datasheet, TS880ICT pinout, TS880ICT application, or TS880ICT equivalent, key selection criteria include its sub-µA quiescent current at 0.9 V supply, built-in 2.5–3.1 mV hysteresis, rail-to-rail input common-mode range, open-drain output compatibility with I²C-level pull-ups, and guaranteed operation at automotive-grade temperature extremes.

Technical Context

The TS880ICT implements a CMOS input stage with rail-to-rail input capability spanning (VCC−) −0.2 V to (VCC+) +0.2 V at low supply (0.9 V), and full rail-to-rail at ≥1.1 V. Its internal hysteresis (typ. 2.5–3.1 mV) suppresses noise-induced output oscillation without external feedback.

It uses a single-supply dual-rail architecture where VCC+ and VCC− define the supply differential; inputs operate referenced to both rails, and the open-drain output sinks up to 22 mA at VCC = 2.7 V while requiring an external pull-up for logic-high assertion.

FAQ

What is the minimum operating supply voltage for TS880ICT?

The TS880ICT operates down to 0.9 V (VCC+ − VCC−), verified across –40 °C to +125 °C. At this voltage, rail-to-rail input range is maintained as (VCC−) −0.2 V to (VCC+) +0.2 V, and supply current remains ≤480 nA. This enables direct integration with primary lithium and alkaline cells without pre-regulation.

Does TS880ICT require external hysteresis components?

No. TS880ICT integrates 2.5–4.2 mV of input hysteresis across temperature, eliminating the need for external resistors. This is confirmed in Tables 3–6 of DS12948 Rev 2, where hysteresis is specified as a guaranteed parameter-not a typical value-and functions independently of external circuitry.

Can TS880ICT drive an LED directly?

Yes. With VCC = 2.7 V, TS880ICT sinks up to 22 mA (Table 5), sufficient to drive standard indicator LEDs at ~2 mA with series resistor. The open-drain output requires an external pull-up to the LED anode supply; sinking current through the LED cathode to VCC− completes the path.

How does TS880ICT handle input voltages beyond the supply rails?

Per Absolute Maximum Ratings (Table 1), input voltage must stay within (VCC−) −0.3 V to (VCC+) +0.3 V. Exceeding this risks latch-up or damage. Input bias current stays ≤100 pA across temperature, but external clamping diodes are recommended if overvoltage risk exists-especially in portable ESD-prone environments.
