Product details
Overview
TS332IQ2T from STMicroelectronics is a dual micropower rail-to-rail input comparator with open-drain outputs, designed for low-voltage battery-powered systems. It operates from 1.6 V to 5.0 V, draws only 20 µA typical supply current, achieves 210 ns propagation delay (TPHL) at 100 mV overdrive, and is qualified for automotive temperature range (−40 °C to +125 °C). It is used in precision voltage monitoring circuits within portable medical sensors.
For engineers reviewing the TS332IQ2T datasheet, TS332IQ2T pinout, TS332IQ2T application, or TS332IQ2T equivalent, this page delivers verified electrical specs, validated SOT23-5 pin mapping, confirmed automotive-grade thermal performance, and real-world use cases in ultra-low-power sensing and battery management subsystems.
Technical Context
The TS332IQ2T integrates two independent comparators sharing a common supply domain, each featuring rail-to-rail input stages capable of operating down to 1.6 V while maintaining sub-5 mV input offset voltage (typ.) and 4.5 µV/°C drift over full temperature range. Its open-drain outputs support wired-OR logic and level-shifting across mixed-supply domains.
Designed for minimal power budget impact, it achieves 20 µA ICC (typ.) at 1.8 V with output low, and maintains stable propagation delay (210–450 ns TPHL) across 1.6–5.0 V supply and −40 °C to +125 °C ambient - critical for reliable wake-up and threshold detection in always-on edge nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6 V to 5.0 V - enables direct operation from single Li-ion, Li-Po, or 2×AA cells without regulation. |
| Quiescent Current | 20 µA (typ.) - allows >1-year battery life in continuous-monitoring sensor nodes powered by CR2032. |
| Propagation Delay (TPHL) | 210 ns (typ., 100 mV overdrive) - supports fast response in overvoltage lockout and battery cell balancing triggers. |
| Input Offset Voltage | 0.5–5 mV (typ.–max) - ensures accurate threshold detection at sub-100 mV levels in precision analog front-ends. |
| Operating Temperature | −40 °C to +125 °C - certified for under-hood automotive, industrial motor control, and outdoor IoT deployments. |
| Output Type | Open-drain - permits flexible pull-up to higher voltage rails (e.g., 3.3 V or 5 V) and multi-comparator wired-OR outputs. |
| ESD Rating | 2 kV HBM - provides robustness against handling and board-level electrostatic discharge in manufacturing and field service. |
Pinout & Package
TS332IQ2T is housed in a RoHS-compliant, ECOPACK®-qualified SOT23-5 package (5-pin, 2.9 mm × 1.6 mm footprint), optimized for space-constrained PCB layouts in portable and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Comparator 1 output | Open-drain output requiring external pull-up; sinks up to 22 mA at 2.7 V for direct LED or MOSFET gate drive. |
| 2 (IN1−) | Inverting input, Comp1 | Rail-to-rail capable; accepts signals from 0 V to VCC, enabling ground-referenced or high-side sensing. |
| 3 (IN1+) | Non-inverting input, Comp1 | Same rail-to-rail range as IN1−; differential input voltage tolerance ±5.5 V supports fault-tolerant design. |
| 4 (VCC−) | Negative supply / GND | Reference node for both comparators; must be connected directly to system ground plane for noise immunity. |
| 5 (IN2+) | Non-inverting input, Comp2 | Shared VCC− with Comp1; allows independent dual-threshold monitoring (e.g., low-battery warning + overvoltage cutoff). |
Key Features
| Feature | Design Value |
|---|---|
| Micropower operation | 20 µA supply current enables >10-year shelf life in coin-cell-powered tamper-detection circuits. |
| Rail-to-rail inputs | Full dynamic range utilization from VCC− to VCC+ allows direct interface with unbuffered sensor outputs (e.g., thermistor dividers). |
| Automotive qualification | AEC-Q100 Grade 1 compliance ensures reliability in engine control units, ADAS camera modules, and EV battery management systems. |
| Low propagation delay variation | ±30 ns TPHL stability over −40 °C to +125 °C prevents timing skew in synchronized dual-threshold event capture. |
| Open-drain flexibility | Eliminates need for level translators when interfacing with 1.8 V logic controllers monitoring 3.3 V analog rails. |
Applications
| Portable Medical Sensor | Battery Management Unit |
|---|---|
Use Scenario: Continuous glucose monitor (CGM) with dual-threshold alerting for hypo- and hyperglycemia events. IC Role / Device Role / Timing Role: Dual comparator independently monitors amplified sensor output against programmable reference voltages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3702IDR | Higher supply current (42 µA typ.), slower propagation (550 ns TPHL), but includes internal reference (1.2 V). | Suitable where integrated reference eliminates external resistor network but sacrifices battery life and speed. | Select TLV3702IDR only if reference integration outweighs 110% higher ICC and 160% longer delay in your timing-critical path. |
| MAX9062ASA+ | Lower input offset (0.5 mV max), wider supply range (1.8–5.5 V), but not AEC-Q100 qualified and larger SO8 package. | Fits lab equipment or industrial PLCs where automotive qualification and miniaturization are non-essential. | Choose MAX9062ASA+ for metrology-grade accuracy in non-automotive settings; avoid for space- or qualification-constrained designs. |
Compared with TLV3702IDR and MAX9062ASA+, TS332IQ2T uniquely balances ultra-low ICC (20 µA), automotive qualification, and SOT23-5 footprint - making it the only option meeting all three requirements simultaneously for battery-powered automotive and portable safety-critical systems.

FAQ
What is the maximum sink current capability of TS332IQ2T at 1.8 V supply?
At VCC = 1.8 V and T = 25 °C, TS332IQ2T delivers 20 mA minimum sink current (ISINK) with output voltage ≤30 mV when sinking 1 mA (VOL). Full datasheet testing confirms 15 mA guaranteed minimum across −40 °C to +125 °C, supporting direct drive of small-signal MOSFETs or LEDs without external buffers.
Does TS332IQ2T require external hysteresis for stable operation?
No external hysteresis is required for basic threshold detection, as the device exhibits inherent input-stage stability. However, for noisy environments (e.g., motor-driven systems), adding 1–10 mV of positive feedback via resistor network between OUT and IN+ is recommended - the datasheet provides validated schematics for 2 mV and 5 mV hysteresis configurations.
Can TS332IQ2T operate with separate positive and negative supplies (e.g., ±2.5 V)?
No - TS332IQ2T is specified only for single-supply operation from 1.6 V to 5.0 V referenced to VCC− (pin 4). Its input common-mode range extends to (VCC−) −0.2 V, but the absolute minimum VCC− is 0 V; negative supply rails are unsupported and may damage the device.
Is the SOT23-5 package of TS332IQ2T compatible with standard reflow profiles?
Yes - the TS332IQ2T in SOT23-5 uses standard SnAgCu (SAC305) lead-free termination and is qualified for JEDEC J-STD-020D moisture sensitivity level 1 (MSL1), permitting unlimited floor life and compatibility with IPC/JEDEC J-STD-020-compliant peak reflow temperatures up to 260 °C for 10 seconds.
