Product details
Overview
TLV2352IPWR from Texas Instruments is a dual low-voltage differential comparator IC designed for single-supply operation with 2.7V to 8V supply range, 200ns typical response time (TTL-level step, 3V/5V), 120µA typical supply current at 3V, and N-channel open-drain outputs requiring external pullup - used in battery-powered voltage monitoring and precision threshold detection circuits.
For engineers reviewing the TLV2352IPWR datasheet, TLV2352IPWR pinout, TLV2352IPWR application, or TLV2352IPWR equivalent, this page delivers verified electrical specs, TSSOP-8 package details, real-world use cases, and two validated alternative comparators with documented functional and thermal differences.
Technical Context
The TLV2352IPWR implements two independent CMOS-based comparators with rail-to-rail input common-mode range including ground, enabling direct sensing of signals referenced to system ground. Its high input impedance (>10¹²Ω) and ultra-low input bias current (5pA typical) minimize loading on high-impedance sources like sensor bridges or photodiode amplifiers.
Each comparator features an N-channel open-drain output stage compatible with TTL, MOS, and CMOS logic families when paired with an external pullup resistor. The device is fully characterized across –40°C to +85°C and supports wired-AND configurations via shared pullup, making it suitable for multi-input logic arbitration and window comparator topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 8V - enables operation from single Li-ion cell (3.0–3.7V) up to industrial 5V/8V rails without level-shifting. |
| Typical Supply Current | 120µA at 3V - supports >1-year battery life in always-on low-power monitoring nodes. |
| Response Time | 200ns (TTL-level input step, 3V/5V) - sufficient for fast overvoltage/undervoltage fault detection in DC-DC converters. |
| Input Offset Voltage | 5mV max at 25°C - ensures reliable 10mV-level threshold discrimination in precision sensing applications. |
| Input Bias Current | 5pA typical - preserves signal integrity when interfacing with megohm-range sensors or RC timing networks. |
| Common-Mode Input Range | Includes ground (0V to VDD–1.25V at 3V) - allows direct comparison of signals referenced to system ground without input biasing. |
| ESD Rating | 1000V HBM - meets basic handling robustness requirements for assembly in non-ESD-controlled environments. |
Pinout & Package
TSSOP-8 (PW) package: 3.0mm × 4.4mm body, 0.65mm pitch, thin-profile surface-mount design optimized for space-constrained PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Comparator A) | Accepts reference or threshold voltage; high-impedance node minimizes source loading. |
| 2 | Non-inverting input (Comparator A) | Connects to sensed signal; common-mode range includes ground for single-supply compatibility. |
| 3 | Output (Comparator A) | N-channel open-drain - requires external pullup to define logic-high level and enable wired-AND logic. |
| 4 | GND | Ground reference for both comparators and internal circuitry; must be low-impedance return path. |
| 5 | Output (Comparator B) | Independent open-drain output; electrically isolated from Output A for separate logic functions. |
| 6 | Non-inverting input (Comparator B) | Second sensing channel; identical electrical characteristics to Pin 2. |
| 7 | Inverting input (Comparator B) | Second reference input; matches Pin 1 performance and layout sensitivity. |
| 8 | VDD | Positive supply rail (2.7V–8V); decoupling capacitor required near pin for noise immunity. |
Key Features
| Feature | Design Value |

| –40°C to +85°C operating range | Validated for industrial temperature environments including automotive cabin and factory automation equipment. |
Applications
| Battery Voltage Monitor | Power Supply Sequencing |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage during charging/discharging to trigger under-voltage lockout (UVLO) and over-voltage protection (OVP). IC Role / Device Role / Timing Role: Dual comparator configured as window detector - one channel compares against 2.5V UVLO threshold, the other against 4.3V OVP threshold. Use Value: 120µA quiescent current extends battery runtime; 200ns response ensures immediate shutdown before cell damage occurs. |
Use Scenario: Enforcing strict power-up order across multiple rails (e.g., 1.2V core before 3.3V I/O) in FPGA or ASIC systems. IC Role / Device Role / Timing Role: Comparator A monitors 1.2V rail and enables 3.3V regulator only after stable; Comparator B verifies 3.3V before releasing system reset. Use Value: Rail-to-rail input range allows direct sensing without resistor dividers; open-drain outputs interface cleanly with enable pins and reset generators. |
| Sensor Threshold Detector | Industrial Level Shifter |
Use Scenario: Converting analog output from a 10MΩ thermistor network into digital alarm signal at 25°C ±2°C. IC Role / Device Role / Timing Role: Single comparator compares thermistor divider voltage against precision reference; second comparator unused or configured for hysteresis. Use Value: 5pA input bias current prevents measurement error from thermistor self-heating; 5mV offset ensures <±0.5°C detection accuracy. |
Use Scenario: Translating 0–2.5V analog sensor output to 0–5V logic-compatible signal for microcontroller ADC input. IC Role / Device Role / Timing Role: Comparator acts as rail-to-rail level translator - reference set to 2.5V, input drives IN+; output pulled to 5V via external resistor. Use Value: Ground-referenced input range accepts unbuffered sensor signals; open-drain output avoids contention with existing 5V bus drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV393IDR | Higher supply current (125µA typ @ 3V), slower response (300ns), wider supply range (2.7V–5.5V only) | Limited to ≤5.5V systems; less suitable for 8V industrial rails | Choose LMV393IDR only if 5.5V max supply and lower cost are prioritized over speed and rail flexibility. |
| TLV3702IPWR | Lower input offset (1.5mV max), faster response (170ns), same TSSOP-8 package and 2.7V–16V supply range | Extended voltage range supports 12V/15V systems; improved accuracy benefits precision thresholds | Choose TLV3702IPWR when tighter offset spec or higher supply voltage headroom is required; pinout-compatible drop-in upgrade. |
Compared with TLV2352IPWR, LMV393IDR trades speed and voltage range for marginally lower cost, while TLV3702IPWR offers superior accuracy and speed within the same footprint - making it a direct performance upgrade for new designs requiring tighter thresholds or broader supply compatibility.

FAQ
What is the maximum supply voltage rating for TLV2352IPWR?
The absolute maximum supply voltage for TLV2352IPWR is 8V, as specified in Section 5.1 of the datasheet. Operation beyond this limit risks permanent damage. The recommended operating range is 2.7V to 8V - distinct from other variants like TLV2352IDR which share this extended range, unlike earlier versions rated down to 2V.
Does TLV2352IPWR support rail-to-rail input operation?
Yes, TLV2352IPWR supports rail-to-rail input common-mode voltage range including ground (0V), verified across its full operating temperature range (–40°C to +85°C). At VDD = 3V, the valid input range is 0V to 1.75V; at VDD = 5V, it extends to 0V to 3.75V - enabling direct interfacing with ground-referenced sensors without level-shifting circuitry.
Can TLV2352IPWR outputs drive TTL logic directly?
No - TLV2352IPWR features N-channel open-drain outputs that require an external pullup resistor to establish a defined logic-high voltage. When properly pulled up to a compatible rail (e.g., 3.3V or 5V), the output is TTL-, MOS-, and CMOS-compatible per datasheet Section 1. This architecture enables wired-AND logic but prohibits direct push-pull TTL driving without external components.
What is the typical input bias current of TLV2352IPWR at 25°C?
The typical input bias current of TLV2352IPWR is 5pA at 25°C, as confirmed in Section 5.3 Electrical Characteristics. This ultra-low value results from TI's CMOS process and ensures minimal loading on high-impedance sources such as photodiodes, piezoelectric sensors, or RC timing networks - preserving signal fidelity and measurement accuracy.
Is TLV2352IPWR pin-compatible with TLV2352IDR?
Yes, TLV2352IPWR (TSSOP-8) and TLV2352IDR (SOIC-8) share identical pin configuration and electrical functionality, but differ in package type, thermal performance, and board area. Both use the same 8-pin dual-in-line arrangement with matching signal assignments - however, PCB layout must accommodate TSSOP's narrower body (3.0mm × 4.4mm) versus SOIC's wider footprint (3.9mm × 4.9mm).
