Product details
Overview
TS882IYST from STMicroelectronics is an automotive-grade dual nanopower rail-to-rail 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 built-in input hysteresis (2.4 mV typ.), push-pull outputs, and AEC-Q100 qualification for use in battery-critical vehicle subsystems such as door module voltage monitoring and body control unit wake-up detection.
For engineers reviewing the TS882IYST datasheet, TS882IYST pinout, TS882IYST application, or TS882IYST equivalent, this page delivers verified electrical specs, MiniSO8 package details, automotive temperature range (-40 °C to +125 °C), ESD robustness (8 kV HBM), and real-world design context for ultra-low-power analog signal conditioning.
Technical Context
The TS882IYST implements a CMOS input stage with rail-to-rail common-mode input range extending 0.2 V beyond rails and push-pull output stage capable of sourcing/sinking ≥1 mA at 1.2 V supply. Its internal hysteresis (2.4 mV typ.) eliminates oscillation near threshold without external components.
It operates across 1.1–5.5 V supply with stable 220 nA/channel quiescent current over -40 °C to +125 °C, and maintains <6 mV input offset voltage and >68 dB CMRR under full temperature and supply variation - enabling reliable threshold detection in noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.1 V to 5.5 V - supports direct connection to single-cell LiFePO₄, alkaline, or automotive 12 V rail via LDO. |
| Quiescent current | 220 nA per channel typ. at 1.2 V - extends battery life in always-on vehicle sensors by >10× vs. µA-class comparators. |
| Propagation delay | 2 µs typ. at 100 mV overdrive - enables fast wake-up response for intrusion detection or ignition status sensing. |
| Input hysteresis | 2.4 mV typ. - suppresses noise-induced false triggering on slow-moving signals like thermistor or potentiometer outputs. |
| Input offset voltage | ±6 mV max over temperature - ensures consistent trip-point accuracy in cabin temperature monitoring circuits. |
| Output drive | Push-pull, VOH = 1.10 V min / VOL = 70 mV max at 0.2 mA - directly interfaces with 1.2 V logic or MCU GPIO without level-shifting. |
| ESD tolerance | 8 kV HBM - meets automotive system-level ESD immunity requirements for exposed sensor inputs. |
Pinout & Package
TS882IYST is housed in an automotive-qualified MiniSO8 package (3.0 mm × 4.9 mm, 0.65 mm pitch), featuring wettable flanks for automated optical inspection and thermal resistance of 190 °C/W (junction-to-ambient).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Push-pull active-high/low output; sinks up to 1.7 mA, sources up to 1.0 mA at 1.2 V. |
| 2 (IN1−) | Channel 1 inverting input | Rail-to-rail input; accepts voltages from V− −0.2 V to V+ +0.2 V. |
| 3 (IN1+) | Channel 1 non-inverting input | Same rail-to-rail range; differential input voltage limited to ±6 V. |
| 4 (V−) | Negative supply / ground | Reference node for both channels; must be connected to system ground or lowest supply rail. |
| 5 (V+) | Positive supply | Accepts 1.1–5.5 V; powers both comparators and output stage. |
| 6 (IN2+) | Channel 2 non-inverting input | Independent input with identical specs to IN1+; no crosstalk guaranteed. |
| 7 (IN2−) | Channel 2 inverting input | Independent input; supports separate reference or signal paths per channel. |
| 8 (OUT2) | Channel 2 output | Electrically isolated output; shares V+ and V− but has independent switching behavior. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power operation | 220 nA/channel typ. enables multi-year battery life in wireless tire pressure sensors and smart key fobs. |

Applications
| Door Module Voltage Monitor | Engine Coolant Level Sensor |
|---|---|
|
Use Scenario: Detects undervoltage condition in 12 V supply feeding power windows and locks during cold cranking. IC Role / Device Role / Timing Role: Dual comparator monitors VBAT and regulated 5 V rail simultaneously; one channel triggers low-V alert, the other validates regulator health. Use Value: 220 nA quiescent current prevents parasitic drain during vehicle sleep mode; 2 µs response ensures timely shutdown before microcontroller brownout. |
Use Scenario: Converts float-switch analog position into digital level indication for coolant reservoir. IC Role / Device Role / Timing Role: Single comparator compares float voltage against precision reference; hysteresis prevents chatter at fill/empty thresholds. Use Value: Rail-to-rail input accepts full 0–5 V sensor swing; push-pull output drives LED driver directly without pull-up resistor. |
| Body Control Unit Wake-Up | Smart Rearview Mirror Dimming |
|
Use Scenario: Detects door handle capacitance change to wake BCM from deep sleep. IC Role / Device Role / Timing Role: One comparator channel amplifies and thresholds AC-coupled sense signal; second channel validates supply stability before wake. Use Value: 1.1 V minimum supply allows operation during battery sag; 8 kV HBM withstands ESD from human touch. |
Use Scenario: Compares forward-facing ambient light sensor output against rear-facing glare sensor to trigger auto-dimming. IC Role / Device Role / Timing Role: Dual comparator implements differential light-level comparison with hysteresis to avoid flicker during transition zones. Use Value: Matched offset (<6 mV) ensures consistent dimming threshold across temperature; 125 °C rating supports dash-mounted placement. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7012DR | Higher ICC (600 nA typ.), no built-in hysteresis, 1.6 V min supply | Requires external hysteresis resistors; unsuitable for 1.2 V systems | Select only if higher speed (1.8 µs) and 3.3 V operation are prioritized over battery life and simplicity. |
| MAX9022ASA+ | Higher ICC (1.1 µA typ.), wider supply (1.8–5.5 V), no AEC-Q100 qualification | Lacks automotive temperature and reliability validation; not approved for safety-critical modules | Use only in industrial or consumer portable designs where AEC-Q100 is not mandated. |
Compared with TLV7012DR and MAX9022ASA+, TS882IYST uniquely combines AEC-Q100 Grade 1 qualification, 1.1 V operation, built-in hysteresis, and sub-250 nA current - making it the only drop-in solution for automotive battery-monitoring and wake-up functions requiring zero external components and extended shelf life.

FAQ
What is the maximum operating temperature for TS882IYST?
The TS882IYST is qualified for continuous operation from −40 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 1 requirements. Its thermal resistance (RθJA) is 190 °C/W in MiniSO8, and junction temperature must remain below 150 °C under all conditions.
Does TS882IYST require external hysteresis resistors?
No. The TS882IYST integrates 2.4 mV typical input hysteresis, eliminating the need for external positive feedback resistors. This simplifies PCB layout, reduces component count, and ensures consistent hysteresis across temperature and supply voltage variations.
Can TS882IYST operate from a single 1.2 V alkaline cell?
Yes. With a minimum supply voltage of 1.1 V and 220 nA typical current per channel at 1.2 V, the TS882IYST is explicitly designed for single-cell battery operation - including aging cells down to ~1.1 V - while maintaining full rail-to-rail input and push-pull output functionality.
Is the MiniSO8 package of TS882IYST compatible with standard SO8 footprints?
No. The MiniSO8 package (3.0 mm × 4.9 mm) is smaller than standard SO8 (3.9 mm × 4.9 mm) and uses 0.65 mm lead pitch versus 1.27 mm. It requires dedicated land pattern per ST's AN4285 footprint recommendation and is not mechanically or solder-reflow compatible with legacy SO8 layouts.
