Product details
Overview
TS3022IYST from STMicroelectronics is a rail-to-rail input, push-pull output dual high-speed comparator qualified for automotive applications (AEC-Q100 Grade 1). It delivers 38 ns propagation delay at 2 V supply, consumes only 73 µA quiescent current, operates from 1.8–5 V, and supports –40 °C to +125 °C ambient temperature - enabling use in engine control unit voltage monitoring and battery management signal conditioning.
For engineers reviewing the TS3022IYST datasheet, TS3022IYST pinout, TS3022IYST application, or TS3022IYST equivalent, key selection considerations include its micropower/high-speed tradeoff (73 µA @ 38 ns), rail-to-rail input common-mode range up to VCC + 0.2 V, push-pull output drive capability (±26 mA at 3.3 V), and AEC-Q100 qualification for under-hood automotive systems.
Technical Context
The TS3022 employs a fully differential input stage with rail-to-rail common-mode input range extending from VCC– – 0.2 V to VCC+ + 0.2 V at 25 °C, degrading to VCC– to VCC+ above +85 °C. Its internal architecture enables fast overdrive recovery and low input offset drift (3–20 µV/°C).
It features complementary push-pull CMOS outputs capable of sourcing 26 mA and sinking 24 mA at 3.3 V, eliminating external pull-up resistors. The device achieves 79 dB CMRR and 73 dB supply voltage rejection across 2–5 V supply variation, supporting stable operation in noisy automotive power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 38 ns typical at 2 V, 100 mV overdrive - enables >10 MHz comparator-based sampling in portable telecom front-ends. |
| Supply voltage range | 1.8–5 V - supports direct interface with 1.8 V logic, 3.3 V microcontrollers, and 5 V analog sensors without level-shifting. |
| Quiescent current | 73 µA typical at 2 V - allows continuous operation in always-on automotive subsystems with sub-150 µA total budget. |
| Input offset voltage | 0.2–6 mV typical (25 °C), ≤7 mV over full temperature range - ensures <10 mV decision error in precision threshold detection. |
| Output type | Push-pull CMOS - drives 10 kΩ loads directly; no external pull-up needed, reducing BOM count and PCB area in space-constrained modules. |
| Operating temperature | –40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood placement in ADAS camera power supervisors and motor phase comparators. |
| ESD tolerance | 5 kV HBM, 300 V MM - provides robustness against handling and board-level ESD events in automotive manufacturing environments. |
Pinout & Package
TS3022IYST is supplied in MiniSO-8 package (3.0 × 4.9 mm, 0.65 mm pitch), optimized for high-density automotive PCB layouts. Thermal resistance junction-to-ambient is 90 °C/W, enabling reliable operation at 125 °C ambient with minimal copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN–A) | Inverting input, Channel A | Rail-to-rail capable; accepts signals from 0 V to VCC + 0.2 V - enables direct sensing of battery voltage or sensor output without clamping diodes. |
| 2 (IN+A) | Non-inverting input, Channel A | Matches IN–A characteristics; differential input voltage range ±5 V - supports large-signal transient detection in fault-monitoring circuits. |
| 3 (OUTA) | Push-pull output, Channel A | Sources/sinks up to 26 mA at 3.3 V - directly drives LED indicators, logic inputs, or small MOSFET gates without buffering. |
| 4 (V–) | Negative supply / ground reference | Connected to system GND; all voltages referenced to this node - requires low-impedance ground plane to maintain 38 ns timing accuracy. |
| 5 (V+) | Positive supply | Accepts 1.8–5 V; decoupling with 100 nF + 10 nF + 1 nF capacitors recommended per application note DS6029 - suppresses supply noise-induced false triggering. |
| 6 (IN–B) | Inverting input, Channel B | Electrically identical to IN–A; independent channel allows dual-threshold detection (e.g., overvoltage + undervoltage) in single-package solution. |
| 7 (IN+B) | Non-inverting input, Channel B | Matches IN–B; enables synchronous comparison of two independent analog signals - used in window comparators for battery cell balancing. |
| 8 (OUTB) | Push-pull output, Channel B | Independent of OUTA; supports OR'ed logic outputs or separate interrupt signaling - reduces need for external logic gates in safety-critical monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Common-mode range extends to VCC + 0.2 V at 25 °C - eliminates input attenuation networks when monitoring 5 V sensor rails with 3.3 V supplies. |
| Push-pull output architecture | No external pull-up required; 40 mV VOL at 1 mA sink (3.3 V) - ensures clean TTL/CMOS-compatible logic transitions without rise-time degradation. |
| AEC-Q100 Grade 1 qualification | Tested per stress conditions including HTOL, TC, UHAST, and ESD - certifies suitability for engine control, transmission, and body electronics modules. |
| Low-input-bias-current design | IIB = 86–160 nA typical - minimizes voltage error across high-impedance divider networks (e.g., 1 MΩ dividers add <0.2 mV error). |
| Wide supply rejection | SVR = 58–73 dB across 2–5 V - maintains stable trip points despite ±100 mV ripple on 3.3 V domain powering microcontroller peripherals. |
Applications
| Engine Control Unit Voltage Monitor | Automotive Camera Power Supervisor |
|---|---|

Use Scenario: Real-time monitoring of 5 V MCU supply and 12 V battery rail in engine control units to trigger fail-safe shutdown during brownout or overvoltage. IC Role / Device Role / Timing Role: Dual comparator configured as window detector; Channel A monitors low threshold (4.75 V), Channel B monitors high threshold (5.25 V). Use Value: 38 ns response ensures detection of <100 ns supply glitches; push-pull outputs directly assert MCU reset pin without RC delay. |
Use Scenario: Validating stable 3.3 V and 1.8 V power rails before enabling image sensor and ISP in ADAS forward-facing cameras. IC Role / Device Role / Timing Role: Independent channels verify both rails simultaneously; outputs feed OR gate to generate single "power OK" signal. Use Value: Rail-to-rail inputs accept full 0–3.3 V range without attenuation; 73 µA ICC enables always-on supervision with <1 µA system standby impact. |
| EV Battery Cell Balancing Controller | Portable Medical Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3502IDR | 3.5 ns propagation delay, 85 µA ICC, 2.7–5.5 V supply - faster but higher power and narrower supply range. | Not AEC-Q100 qualified; suited for industrial test equipment, not automotive under-hood use. | Select when nanosecond response is critical and automotive qualification is unnecessary. |
| LMH7322MA/NOPB | 2.5 ns delay, 7.5 mA ICC, 2.7–12 V supply - significantly faster but 100× higher current draw. | Designed for RF/IF signal chain applications; lacks rail-to-rail inputs and automotive screening. | Choose only for high-frequency instrumentation where speed outweighs power and input range constraints. |
Compared with TLV3502IDR and LMH7322MA/NOPB, TS3022IYST uniquely balances sub-40 ns speed, micropower operation (73 µA), rail-to-rail inputs, and AEC-Q100 qualification - making it the only viable option for automotive power monitoring where thermal and supply constraints prohibit higher-current alternatives.

FAQ
What is the maximum input common-mode voltage for TS3022IYST at +125 °C?
At +125 °C, the input common-mode voltage range is VCC– to VCC+ (0 V to VCC), per Table 2 of DS6029 Rev 6. This is reduced from VCC– – 0.2 V to VCC+ + 0.2 V at 25 °C to ensure stability and avoid input stage saturation at extreme temperatures.
Can TS3022IYST drive a 50 Ω transmission line directly?
No. TS3022IYST outputs are rated for 10 kΩ loads (per electrical characteristics tables); driving 50 Ω would exceed its 26 mA source/24 mA sink capability at 3.3 V and cause excessive VOL/VOH shift and potential thermal stress. A dedicated line driver IC is required for 50 Ω termination.
Does TS3022IYST require external hysteresis for noise immunity?
Not inherently - its 38 ns propagation delay and 79 dB CMRR provide inherent noise rejection for moderate EMI environments. However, external hysteresis (e.g., 10 MΩ feedback resistor) is recommended for noisy automotive power rails or high-impedance sensor inputs to prevent multiple toggling near threshold.
Is the MiniSO-8 package of TS3022IYST RoHS and REACH compliant?
Yes. TS3022IYST carries ECOPACK2 compliance per STMicroelectronics' environmental program, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound as documented in DS6029 Section 5.
