STMicroelectronics TS882IQ2T

Overview

TS882IQ2T from STMicroelectronics is a dual rail-to-rail nanopower comparator with 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 hysteresis, and operates across –40 °C to +125 °C - enabling ultra-low-power voltage monitoring in battery-powered medical sensors.

For engineers reviewing the TS882IQ2T datasheet, TS882IQ2T pinout, TS882IQ2T application, or TS882IQ2T equivalent, key selection criteria include its sub-µA quiescent current at 1.1 V supply, guaranteed rail-to-rail input common-mode range, push-pull output drive capability without external pull-up, and DFN8 (2 × 2 mm) package compatibility with space-constrained portable designs.

Technical Context

The TS882IQ2T integrates two independent comparators with internal hysteresis (1.5–4.2 mV), rail-to-rail input stages that function down to 1.1 V supply, and push-pull CMOS outputs capable of sourcing/sinking ≥1 mA at 1.2 V. Its input bias current remains ≤100 pA over temperature, minimizing leakage-induced errors in high-impedance sensing nodes.

Propagation delay is specified at 2.1–4.2 µs (depending on overdrive and supply), with power-up time under 1.7 ms and supply voltage rejection ratio of 65–80 dB - supporting stable threshold detection in noisy, low-voltage automotive and industrial sensor interfaces.

Key Specifications

Pinout & Package

TS882IQ2T is housed in a thermally enhanced DFN8 (2 × 2 mm, 0.5 mm pitch) package with exposed thermal pad. This 8-terminal leadless package supports high-density PCB layouts and improved thermal performance (R_θJA = 57 °C/W) versus MiniSO8.

FAQ

What is the minimum supply voltage for reliable operation of TS882IQ2T?

The TS882IQ2T is fully specified to operate down to 1.1 V supply voltage across –40 °C to +125 °C, with all key parameters including propagation delay, input offset, and output drive guaranteed per datasheet Table 3. Below 1.1 V, functionality is not characterized and may be unstable.

Does TS882IQ2T require external hysteresis components?

No. The TS882IQ2T includes built-in input hysteresis of 1.5–4.2 mV (typ. 2.4 mV), eliminating the need for external positive feedback resistors. This is confirmed in datasheet Section 3 Electrical Characteristics and Figure 10/12, which show hysteresis vs. temperature and supply.

Can TS882IQ2T drive a standard CMOS logic input directly?

Yes. Its push-pull output delivers VOH ≥1.10 V and VOL ≤70 mV at 0.2 mA load with 1.2 V supply, meeting standard 1.2 V logic thresholds. At 2.7 V and 5 V supplies, output swing exceeds 2.4 V and 4.75 V respectively - compatible with 1.8 V, 3.3 V, and 5 V logic families.

Is TS882IQ2T qualified for automotive applications?

No - TS882IQ2T is the industrial-grade variant in DFN8. For automotive use, ST specifies TS882IYST (MiniSO8, AEC-Q100 qualified). TS882IQ2T shares identical electrical specs but lacks automotive screening and qualification documentation per AEC-Q100 Rev D.
