Product details
Overview
TS334IYPT from STMicroelectronics is a quad micropower, rail-to-rail input comparator with open-drain outputs, operating from 1.6 V to 5 V supply and consuming only 20 µA typical supply current. It features 210 ns propagation delay (high-to-low), ±5 mV input offset voltage, and operates across –40 °C to +125 °C - enabling use in battery-powered industrial sensors and automotive body control modules.
For engineers reviewing the TS334IYPT datasheet, TS334IYPT pinout, TS334IYPT application, or TS334IYPT equivalent, key selection criteria include its ultra-low quiescent current, rail-to-rail input range down to 1.6 V, open-drain output compatibility with mixed-voltage logic interfaces, and AEC-Q100 qualification for automotive environments.
Technical Context
The TS334IYPT integrates four independent comparators sharing a common supply domain, each with rail-to-rail input stage enabling full dynamic range utilization at low voltages. Its open-drain outputs support wired-OR configurations and level-shifting without external pull-ups in many cases.
Designed for micropower operation, it uses a CMOS input stage with <100 nA max input bias current and achieves 210 ns propagation delay at 100 mV overdrive with 5.1 kΩ load and 50 pF capacitance - balancing speed and energy efficiency for wake-up and threshold-detection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6 V to 5.0 V - supports direct connection to single-cell Li-ion, LiFePO₄, or 3.3 V/5 V rails without regulation. |
| Quiescent Current | 20 µA typical per comparator - enables multi-comparator monitoring in always-on systems with sub-100 µA total budget. |
| Input Offset Voltage | ±5 mV max at 25 °C - ensures reliable detection of small analog thresholds (e.g., battery voltage sag or temperature trip points). |
| Propagation Delay | 210 ns (TPHL) at 100 mV overdrive - sufficient for fast edge detection in power sequencing or fault latching. |
| Input Common-Mode Range | Rail-to-rail (VCC− to VCC+) - allows direct sensing of signals near supply rails, critical in low-voltage battery monitoring. |
| Output Type | Open-drain - enables flexible pull-up to higher or lower voltage domains and wired-OR logic for alarm aggregation. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial control applications. |
Pinout & Package
TS334IYPT is packaged in a TSSOP14 (Thin Shrink Small Outline Package, 14-pin), 5.0 mm × 4.4 mm × 1.2 mm body, with 0.65 mm lead pitch and wettable flank capability for automated optical solder-joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | IN+ (Non-inverting Input) | Positive input for Comparator 1–4; rail-to-rail capable, accepts signals from VCC− to VCC+. |
| 2, 6, 10, 14 | IN− (Inverting Input) | Negative input for Comparator 1–4; same rail-to-rail range as IN+. |
| 3, 7, 11, 12 | OUT (Open-Drain Output) | Active-low output; requires external pull-up; sinks ≥20 mA at VCC = 2.7 V for direct LED or MOSFET gate drive. |
| 4 | VCC+ | Positive supply pin; accepts 1.6–5.0 V; decoupling capacitor recommended within 1 cm. |
| 8 | VCC− | Ground reference; must be connected directly to system GND plane for stable common-mode rejection. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower Operation | 20 µA per comparator enables 4-channel threshold detection in battery-critical designs (e.g., coin-cell IoT nodes). |
| Rail-to-Rail Inputs | Supports full-supply-range signal comparison without attenuation or level-shifting circuitry. |
| Automotive Qualification | AEC-Q100 Grade 1 qualified - validated for reliability in automotive body electronics and ADAS subsystems. |
| Low Propagation Delay | 210 ns TPHL at 100 mV overdrive ensures timely response in power-fail detection and overvoltage lockout. |
| ESD Robustness | 2 kV HBM - reduces need for external protection in handheld and portable equipment interfaces. |
Applications
| Overvoltage Protection Circuit | Battery Fuel Gauge Interface |
|---|---|
Use Scenario: Monitors DC bus voltage in automotive infotainment power supplies to trigger shutdown before regulator damage. IC Role / Device Role / Timing Role: Quad comparator configures three independent overvoltage thresholds (e.g., 3.6 V, 4.2 V, 4.8 V) with one channel reserved for undervoltage lockout. Use Value: Eliminates discrete Zener + transistor solutions, reducing BOM count by 4× while maintaining <10 µs response time. | Use Scenario: Detects cell voltage crossing predefined thresholds (e.g., 3.0 V, 3.3 V, 3.6 V) in multi-cell Li-ion packs for state-of-charge estimation. IC Role / Device Role / Timing Role: Each comparator independently compares a scaled cell voltage against a precision reference, driving separate GPIOs on an MCU. Use Value: Enables accurate fuel gauging with <±5 mV offset error, supporting 1% SOC resolution without ADC oversampling. |
| Industrial Sensor Wake-Up Logic | Motor Phase Current Monitoring |
Use Scenario: Activates microcontroller sleep mode exit when ambient light, temperature, or pressure crosses preset limits in smart building sensors. IC Role / Device Role / Timing Role: One comparator monitors sensor output; remaining three implement hysteresis and enable timing windows to suppress noise-induced false triggers. Use Value: Reduces average system current to <1 µA in deep sleep while maintaining <1 ms wake latency. | Use Scenario: Detects overcurrent conditions in BLDC motor phase legs using shunt voltage amplification and comparison. IC Role / Device Role / Timing Role: Two comparators monitor high-side and low-side shunt signals; third implements blanking window; fourth drives fault latch. Use Value: Achieves <250 ns total fault detection latency (including propagation + latch setup), meeting IEC 61800-5-2 functional safety timing requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339QDRQ1 | Higher supply range (2–36 V), 1.3 mA supply current, push-pull output - no open-drain flexibility. | Suitable for 12 V automotive systems but incompatible with 1.8 V logic domains due to minimum 2 V supply. | Select when interfacing with legacy 5 V/12 V logic and higher-speed response (>1 µs) is acceptable. |
| TLV3704IPW | Lower offset (±3 mV), 850 nA supply current, rail-to-rail output - lacks AEC-Q100 qualification. | Valid for consumer portables but not approved for automotive production due to missing stress-test validation. | Choose for cost-sensitive, non-automotive applications requiring tighter offset and lower power than TS334IYPT. |
Compared with LM339QDRQ1 and TLV3704IPW, TS334IYPT uniquely combines AEC-Q100 qualification, 20 µA ultra-low quiescent current, and open-drain outputs in a single TSSOP14 package - making it the only option qualified for automotive-grade, battery-constrained, multi-threshold detection systems.

FAQ
What is the maximum sink current capability of TS334IYPT at 1.8 V supply?
At VCC = 1.8 V and Tamb = 25 °C, TS334IYPT delivers a minimum sink current of 20 mA with output voltage ≤30 mV (ISINK test condition: VOUT = 1.5 V). This enables direct driving of LEDs or small-signal MOSFET gates without external buffers in low-voltage applications.
Can TS334IYPT operate with a single 1.6 V supply and still achieve rail-to-rail input performance?
Yes - the datasheet confirms rail-to-rail input common-mode range (VCC− to VCC+) across the full 1.6 V to 5.0 V supply range. At 1.6 V, inputs accept signals from 0 V to 1.6 V, verified per Table 2 (VICM specification) and Figure 7 (input bias current vs. common-mode voltage).
Is the TSSOP14 package of TS334IYPT compatible with standard reflow profiles for lead-free assembly?
Yes - the TS334IYPT TSSOP14 package is RoHS-compliant and qualified for JEDEC J-STD-020D moisture sensitivity level 3. Peak reflow temperature is 260 °C (10 s), matching standard Pb-free profiles; thermal resistance RθJA is 100 °C/W per Table 1.
Does TS334IYPT require external hysteresis resistors for stable operation in noisy environments?
No - internal hysteresis is not provided, but the device supports external positive feedback via resistor networks from OUT to IN+. Typical hysteresis values (e.g., 10–50 mV) can be implemented with two resistors per comparator, leveraging its rail-to-rail input and open-drain output for predictable threshold shifting.
