STMicroelectronics TS883IQ2T

Overview

TS883IQ2T from STMicroelectronics is a dual nanopower open-drain comparator in DFN8 2×2 mm package, designed for ultra-low-power signal threshold detection in battery-constrained systems. It delivers 250 nA typical supply current per channel, rail-to-rail input operation from 0.9 V to 5.5 V supply, and 2 µs typical propagation delay at 100 mV overdrive with 10 kΩ pull-up.

For engineers reviewing the TS883IQ2T datasheet, TS883IQ2T pinout, TS883IQ2T application, or TS883IQ2T equivalent, key selection criteria include its dual-channel nanopower operation, open-drain output compatibility with mixed-voltage logic, -40 °C to +125 °C industrial temperature range, and validated performance down to 0.9 V supply - critical for energy-harvesting sensors and implantable medical devices.

Technical Context

The TS883IQ2T integrates two independent comparators sharing no internal biasing; each operates with separate rail-to-rail inputs and open-drain outputs. Its input stage uses a low-leakage architecture enabling stable offset voltage (±5 mV max at 25 °C) and hysteresis (1.6–4.2 mV) across full temperature and supply range.

Propagation delay is load-dependent: 1.9–3.3 µs (low-to-high) and 1.7–3.5 µs (high-to-low) at 100 mV overdrive with 10 kΩ pull-up, scaling to ~24 µs with 1 MΩ pull-up. Output sink capability reaches 22 mA at VCC = 2.7 V, supporting direct LED drive or logic-level translation without external transistors.

Key Specifications

Pinout & Package

FAQ

What is the maximum sink current capability of TS883IQ2T at 1.2 V supply?

At VCC = 1.2 V, TS883IQ2T delivers 3.6 mA sink current (typical) with VOL ≤ 50 mV at ISINK = 0.2 mA. This is sufficient to drive small-signal MOSFET gates or low-current indicator LEDs without external buffers, preserving nanopower operation while enabling direct actuation.

Does TS883IQ2T require external hysteresis for noise immunity?

No. TS883IQ2T integrates 1.6–4.2 mV of built-in hysteresis across its operating range, eliminating the need for external positive feedback resistors. This simplifies PCB layout, reduces component count, and ensures consistent noise margin regardless of supply voltage or temperature - verified per DS12948 Table 3–6.

Can TS883IQ2T operate with asymmetric supply rails (e.g., VCC+ = 3.3 V, VCC− = -0.3 V)?

Yes. The device supports rail-to-rail inputs referenced to VCC−, allowing VCC− to be biased below ground (e.g., -0.3 V) as long as differential supply VCC remains within 0.9–5.5 V and input voltages stay within (VCC− −0.2 V) to (VCC+ +0.2 V), per Absolute Maximum Ratings Table 1.

Is the DFN8 2×2 mm package of TS883IQ2T RoHS and REACH compliant?

Yes. TS883IQ2T is manufactured in ST's ECOPACK2-compliant DFN8 package, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full compliance documentation, including material declarations and substance thresholds, is available via ST's official product page and ECOPACK portal.
