Product details
Overview
TS332IDT from STMicroelectronics is a dual micropower, rail-to-rail input comparator with open-drain output, 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 typical input offset voltage, and −40 °C to +125 °C temperature range-enabling use in battery-powered industrial sensors and automotive body control modules.
For engineers reviewing the TS332IDT datasheet, TS332IDT pinout, TS332IDT application, or TS332IDT equivalent, this device is selected for ultra-low-power voltage monitoring, precision threshold detection in portable medical devices, and rail-to-rail input signal comparison in space-constrained embedded systems where supply current below 30 µA and operation down to 1.6 V are mandatory.
Technical Context
The TS332IDT integrates two independent comparators sharing a common supply domain, each with rail-to-rail input stage enabling full-supply-range sensing without external level-shifting. Its open-drain outputs support wired-OR logic and flexible pull-up configuration across mixed-voltage domains.
Designed for micropower operation, it achieves 20 µA supply current at 1.8 V while maintaining 210 ns propagation delay under 100 mV overdrive-balancing speed and energy efficiency for wake-up and fault-detection circuits in always-on subsystems.
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 (3.0–3.7 V), LiFePO₄ (2.5–3.6 V), or 1.8/2.5/3.3 V logic rails. |
| Supply Current (Typ.) | 20 µA - enables >1-year battery life in coin-cell-powered IoT endpoints with 100 µA average system budget. |
| Propagation Delay (TPHL) | 210 ns at 100 mV overdrive - sufficient for 1 MHz window-compare timing in motor phase detection or ADC reference monitoring. |
| Input Offset Voltage (Typ.) | 5 mV - allows accurate 10 mV threshold discrimination in low-voltage battery fuel gauging applications. |
| Rail-to-Rail Inputs | Common-mode range extends 0.2 V beyond supply rails - eliminates need for input bias resistors in single-supply sensor interfaces. |
| Output Type | Open-drain - permits level translation to higher voltages (e.g., 5 V pull-up) and wired-OR fault-bus signaling. |
| ESD Rating | 2 kV HBM - meets IEC 61000-4-2 Level 2 for handheld device front-end protection. |
Pinout & Package
TS332IDT is supplied in SO8 package (8-pin small outline integrated circuit), with exposed pad not connected internally. Pin functions are validated per STMicroelectronics DocID17272 Rev 6, Figure 1 and Table 11.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Open-drain output of Comparator 1 - requires external pull-up; sinks up to 22 mA at 2.7 V. |
| 2 | IN1− | Inverting input of Comparator 1 - rail-to-rail capable; common-mode range includes VCC− and VCC+. |
| 3 | IN1+ | Non-inverting input of Comparator 1 - matched to IN1− for <6 mV offset; no internal hysteresis. |
| 4 | VCC− | Negative supply terminal - connects to ground or system reference; all inputs referenced to this node. |
| 5 | IN2+ | Non-inverting input of Comparator 2 - electrically isolated from Comparator 1; identical AC/DC specs. |
| 6 | IN2− | Inverting input of Comparator 2 - supports independent threshold setting; shares same supply domain as OUT1/OUT2. |
| 7 | OUT2 | Open-drain output of Comparator 2 - independently controllable; compatible with 1.8 V to 5 V pull-up rails. |
| 8 | VCC+ | Positive supply terminal - accepts 1.6–5.0 V; supplies both comparators and internal bias circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20 µA typical at 1.8 V - reduces standby power in battery-backed real-time clocks and security tamper detectors. |
| Rail-to-rail input stage | Operates with VICM = (VCC−) − 0.2 V to (VCC+) + 0.2 V - enables direct sensing of 0 V to VCC signals without resistor dividers. |
| Wide temperature range | −40 °C to +125 °C - qualified for under-hood automotive and industrial motor drive control environments. |
| Low propagation delay | 210 ns TPHL at 100 mV overdrive - supports fast response in overvoltage lockout and PWM fault detection circuits. |
| Open-drain output architecture | Supports mixed-voltage interfacing and wired-OR bus configurations - simplifies multi-sensor alarm aggregation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV393QDRQ1 | Higher supply current (48 µA typ.), wider offset (7 mV max), but AEC-Q100 Grade 1 qualified. | Preferred for automotive powertrain applications requiring extended qualification beyond TS332IDT's Grade 0. | Select when AEC-Q100 Grade 1 compliance is mandated and 28 µA extra supply current is acceptable. |
| TLV3702IP | Lower supply current (1 µA typ.), but limited 2.7–16 V supply range and no rail-to-rail inputs. | Suitable for ultra-long-life remote sensors where supply voltage exceeds 2.7 V and input swing stays within mid-rail. | Choose only if system operates ≥2.7 V and input signals avoid rail extremes; not drop-in for 1.6–2.5 V designs. |
Compared with LMV393QDRQ1 and TLV3702IP, TS332IDT uniquely delivers rail-to-rail input operation down to 1.6 V with 20 µA consumption-making it optimal for space- and energy-constrained portable and automotive body electronics where wide input range and minimal quiescent power are jointly required.

FAQ
What is the maximum sink current capability of TS332IDT outputs?
At VCC = 2.7 V and TA = +25 °C, TS332IDT can sink up to 47 mA per output (typical) with VOL ≤ 30 mV at ISINK = 1 mA. The absolute maximum sink current is 22 mA at 2.7 V per output under continuous DC conditions, as specified in Table 4 of the datasheet. Derating applies above 85 °C ambient.
Can TS332IDT operate with a single 1.6 V supply and still achieve rail-to-rail input performance?
Yes. TS332IDT guarantees rail-to-rail input common-mode range from (VCC−) − 0.2 V to (VCC+) + 0.2 V across its full 1.6–5.0 V supply range. At 1.6 V supply, inputs function correctly from −0.2 V to +1.8 V, enabling direct interface with sensors whose outputs swing near ground or VCC without external biasing.
Is the SO8 package of TS332IDT lead-free and RoHS compliant?
Yes. TS332IDT in SO8 package is manufactured per STMicroelectronics' ECOPACK2 standard, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The device carries the "E2" grade marking indicating halogen-free and lead-free construction with matte tin finish on leads.
Does TS332IDT include internal hysteresis, and how should external hysteresis be implemented?
No, TS332IDT has no internal hysteresis. To prevent oscillation near threshold, external positive feedback must be added: connect a resistor from OUTx to INx+ (for non-inverting configuration) or INx− (for inverting). Typical values range from 1 MΩ to 10 MΩ depending on required hysteresis width and source impedance, as detailed in ST Application Note AN2867.
