STMicroelectronics TS884IPT

Overview

TS884IPT from STMicroelectronics is a quad nanopower rail-to-rail comparator with 220 nA typical supply current per channel, 2 µs typical propagation delay, and operation from 1.1 V to 5.5 V. It features push-pull outputs, -40 °C to +125 °C operating range, and 8 kV HBM ESD rating. Used in battery-powered medical sensors and automotive body control modules for ultra-low-power voltage monitoring.

For engineers reviewing the TS884IPT datasheet, TS884IPT pinout, TS884IPT application, or TS884IPT equivalent, key selection criteria include input offset voltage (±6 mV), hysteresis (1.5–4.2 mV), output drive capability at 1.2 V supply, and TSSOP14 package thermal resistance (100 °C/W).

Technical Context

The TS884IPT integrates four independent comparators with built-in hysteresis (1.5–4.2 mV), rail-to-rail input common-mode range extending 0.2 V beyond rails, and push-pull outputs capable of sourcing/sinking up to 1.7 mA at 1.2 V. Its architecture minimizes supply current across temperature (-40 °C to +125 °C) and supply voltage (1.1–5.5 V) without external biasing.

Each comparator exhibits 3 µV/°C input offset drift, 50–78 dB CMRR over full temperature range, and propagation delay variation under 10% across 10 mV to 100 mV overdrive. Power-up time remains stable at 1.1–1.7 ms regardless of supply voltage or load.

FAQ

What is the maximum input common-mode voltage range for TS884IPT at 1.2 V supply?

At VCC = 1.2 V, the input common-mode voltage range is (VCC−) to (VCC+) + 0.2 V, i.e., 0 V to 1.4 V. This rail-to-rail capability allows direct interfacing with resistive dividers referenced to the same supply, eliminating level-shifting circuitry in low-voltage sensor front-ends.

Can TS884IPT drive a 10 kΩ load directly at 1.2 V supply?

Yes - with VOL ≤ 70 mV at 0.2 mA sink current and VOH ≥ 1.10 V at 0.2 mA source current (VCC = 1.2 V), the TS884IPT can reliably drive 10 kΩ loads across its full temperature range. Output swing remains within 10% of rails, supporting clean logic-level signaling into high-impedance MCU inputs.

Does TS884IPT require external hysteresis for noise immunity?

No - the TS884IPT includes internal hysteresis of 1.5–4.2 mV, which suppresses output oscillation caused by slow-moving or noisy input signals. This eliminates the need for external positive feedback resistors, simplifying layout and improving reliability in EMI-prone environments like automotive cabins.

Is the TSSOP14 package of TS884IPT RoHS-compliant and lead-free?

Yes - the TS884IPT in TSSOP14 packaging meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations. ST's ECOPACK® documentation confirms full compliance, including halogen-free substrate and matte tin plating per JEDEC J-STD-020 moisture sensitivity level 1.
