STMicroelectronics TS882IST

Overview

TS882IST from STMicroelectronics is a dual rail-to-rail nanopower comparator with ultra-low 220 nA typical supply current per channel at 1.2 V, 2 µs typical propagation delay, and operation from 1.1 V to 5.5 V. It features push-pull outputs, built-in 2.4 mV typical input hysteresis, and operates across –40 °C to +125 °C - deployed in battery-powered medical sensors and portable instrumentation.

For engineers reviewing the TS882IST datasheet, TS882IST pinout, TS882IST application, or TS882IST equivalent, key selection criteria include nanoscale quiescent current stability over voltage/temperature, rail-to-rail input common-mode range down to V_CC– – 0.2 V, push-pull output drive capability up to 1.7 mA sink/source at 1.2 V, and MiniSO8 package compatibility with space-constrained PCB layouts.

Technical Context

The TS882IST implements a CMOS input stage with integrated hysteresis (1.5–4.2 mV) to prevent oscillation near threshold, enabling reliable single-supply level detection without external feedback. Its rail-to-rail input range extends from V_CC– – 0.2 V to V_CC+ + 0.2 V at full temperature range, supporting direct sensing of low-voltage battery rails or sensor outputs.

Push-pull output architecture delivers VOH = 1.10 V (min) and VOL = 70 mV (max) at 0.2 mA load with 1.2 V supply, eliminating need for external pull-ups. Propagation delay remains stable across 10 mV–100 mV overdrive and supply voltages from 1.1 V to 5.5 V, with TPLH/TPHL varying from 2.1–3.4 µs (typ) depending on conditions.

Key Specifications

Pinout & Package

TS882IST is housed in an 8-pin MiniSO8 package (3.0 mm × 4.9 mm, 0.65 mm pitch), optimized for thermal performance (R_THJA = 190 °C/W) and automated assembly. Pin 1 is marked with a dot; device orientation follows JEDEC MS-012 standard.

FAQ

What is the maximum recommended PCB trace length for TS882IST inputs in high-noise environments?

For optimal noise immunity, keep input traces under 10 mm and route differentially with ground guard traces. The built-in 2.4 mV hysteresis suppresses noise up to ~10 mV_PP at frequencies below 100 kHz; longer traces increase susceptibility to capacitive coupling and require local RC filtering per datasheet Figure 10.

Can TS882IST drive a 10 kΩ pull-down load directly at its output?

Yes - TS882IST's push-pull output sinks up to 1.7 mA at 1.2 V supply, delivering VOL ≤ 70 mV into 10 kΩ (0.12 mA load). This ensures valid logic-low levels for 1.2 V I/O standards; no external transistor buffer is needed for such light loads.

Does TS882IST require external decoupling capacitors, and what value is recommended?

A 100 nF X7R ceramic capacitor placed within 2 mm of pins 4 (V_CC–) and 5 (V_CC+) is mandatory per ST layout guidelines. This stabilizes the internal bias network during output transitions and prevents false triggering caused by supply rail sag during 220 nA-to-1.7 mA current step changes.

How does input offset voltage drift impact accuracy in a –40 °C to +125 °C temperature cycle?

ΔVIO is specified at 3 µV/°C max over full temperature range. Over 165 °C span, worst-case drift is ±495 µV - negligible versus 6 mV max VIO and 2.4 mV hysteresis, ensuring consistent trip-point behavior without calibration in most portable sensing applications.
