Product details
Overview
TS862AIPT from STMicroelectronics is a dual rail-to-rail micropower BiCMOS comparator operating from 2.7 V to 10 V, consuming only 6 µA per channel at 2.7 V, featuring push-pull outputs, 500 ns propagation delay at 100 mV overdrive, and rail-to-rail CMOS inputs - deployed in battery-powered smoke detectors and portable communication systems.
For engineers reviewing the TS862AIPT datasheet, TS862AIPT pinout, TS862AIPT application, or TS862AIPT equivalent, key selection criteria include ultra-low supply current, push-pull output eliminating external pull-ups, input common-mode range extending to both rails, and TSSOP8 package suitability for space-constrained portable designs.
Technical Context
The TS862AIPT implements two independent high-precision comparators with rail-to-rail CMOS inputs enabling full-supply-range sensing, and push-pull CMOS outputs capable of sourcing/sinking 2.5 mA while delivering logic-compatible voltage levels (VOH ≥ 2.35 V, VOL ≤ 0.45 V at 2.7 V). Its BiCMOS process ensures low input bias current (≤600 pA) and low input offset voltage drift (6 µV/°C).
Designed for operation across -40 °C to +85 °C, it maintains stable performance with 65–75 dB common-mode rejection (CMR) and 80 dB supply voltage rejection (SVR) over 2.7–10 V supply, supporting reliable threshold detection in noisy, wide-voltage battery systems without external level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports direct connection to single-cell Li-ion (3.0–4.2 V), two-cell alkaline (2.7–3.6 V), or regulated 5 V/10 V rails. |
| Supply Current per Comparator | 6 µA typical at 2.7 V - enables multi-year operation on coin-cell batteries in always-on sensor wake-up circuits. |
| Propagation Delay | 500 ns at 100 mV overdrive, 2.7 V - provides fast response for dynamic threshold detection in portable alarm triggers. |
| Input Offset Voltage | 3–18 mV over temperature - ensures accurate low-voltage window comparisons (e.g., battery undervoltage lockout at 2.8 V). |
| Output Type | Push-pull CMOS - eliminates need for external pull-up resistors, reducing BOM count and PCB area in microcontroller interface designs. |
| Input Common-Mode Range | Rail-to-rail (VCC− −0.3 V to VCC+ +0.3 V) - allows direct sensing of signals near ground or supply without resistor dividers. |
| ESD Protection | 2 kV HBM - provides robustness against handling discharge in handheld device assembly and field service. |
Pinout & Package
TSSOP8 package: 3 mm × 4.4 mm body, 0.65 mm pitch, 1.2 mm height, lead-free ECOPACK® compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Comp 1) | Accepts reference or sensed signal; rail-to-rail CMOS input enables direct connection to battery or sensor output. |
| 2 | Non-inverting Input (Comp 1) | Accepts variable signal (e.g., thermistor divider); matched input impedance minimizes offset error. |
| 3 | Output (Comp 1) | Push-pull CMOS output drives MCU GPIO directly; no pull-up required for active-high logic interface. |
| 4 | VCC− | Negative supply terminal; connects to system ground in single-supply configurations. |
| 5 | VCC+ | Positive supply terminal; accepts 2.7–10 V; decoupling capacitor recommended at pin. |
| 6 | Output (Comp 2) | Independent push-pull output for second threshold comparison; compatible with same MCU port as Comp 1. |
| 7 | Non-inverting Input (Comp 2) | Second independent input; enables dual-threshold detection (e.g., low-battery warning + critical shutdown). |
| 8 | Inverting Input (Comp 2) | Second reference input; supports differential or single-ended configuration per comparator. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Enables accurate comparison of signals from 0 V to VCC without attenuation or level-shifting circuitry. |
| Push-pull output architecture | Reduces component count by eliminating external pull-up resistors in microcontroller interrupt or enable lines. |
| 6 µA per comparator quiescent current | Extends battery life in always-on applications such as smoke detector standby mode (>5 years on CR2032). |
| 500 ns propagation delay at 100 mV overdrive | Supports rapid response to fault conditions (e.g., gas concentration spike) without compromising power efficiency. |
| Latch-up immunity (Class A) | Guarantees robust operation under transient overvoltage or ESD events in unregulated portable environments. |
Applications
| Smoke Detector Threshold Sensing | Portable Computer Battery Monitoring |
|---|---|
|
Use Scenario: Detecting smoke particle density via optical chamber photodiode current crossing preset thresholds. IC Role / Device Role / Timing Role: Dual comparator performs window comparison - one channel triggers alarm at medium smoke level, second initiates hysteresis-latched shutdown at critical level. Use Value: Ultra-low 6 µA supply current extends CR123A battery life beyond 10 years in standby; rail-to-rail inputs interface directly with transimpedance amplifier output. |
Use Scenario: Monitoring lithium-ion cell voltage during charge/discharge cycles in ultrabooks and tablets. IC Role / Device Role / Timing Role: Comp 1 detects undervoltage lockout (2.8 V), Comp 2 flags overvoltage (4.3 V); push-pull outputs drive MCU GPIOs without external components. Use Value: Eliminates two 10-kΩ pull-up resistors per comparator, saving 0.5 mm² PCB area and reducing BOM cost in high-volume portable designs. |
| Wireless Sensor Node Wake-Up | Gas Detector Alarm Logic |
|
Use Scenario: Waking an ultra-low-power MCU from sleep when ambient light or temperature crosses programmable thresholds. IC Role / Device Role / Timing Role: Comparator output asserts interrupt line; propagation delay <500 ns ensures timely wake-up before sensor data drifts. Use Value: 6 µA total quiescent current (both channels) keeps average system current below 10 µA - compatible with energy-harvesting power budgets. |
Use Scenario: Triggering audible/visual alarms when electrochemical gas sensor output exceeds toxic exposure limits. IC Role / Device Role / Timing Role: Dual comparators implement fail-safe redundant detection - one compares raw sensor output, second validates reference stability. Use Value: Class A latch-up immunity prevents false resets during ESD-prone field deployment; 2 kV HBM rating meets IEC 61000-4-2 Level 2 requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV393IDR | Higher supply current (20 µA/ch), open-drain outputs requiring pull-ups, wider offset (±7 mV), no rail-to-rail inputs. | Suitable for non-battery-critical industrial controls where board space and power are less constrained. | Select if legacy design uses open-drain logic or requires higher drive strength; avoid for coin-cell applications. |
| TLV3702IPWR | Lower supply current (1 µA/ch), rail-to-rail inputs/outputs, but slower propagation (3 µs), limited supply range (2.7–16 V). | Better for multi-year energy harvesting nodes where speed is secondary to ultra-low power. | Prefer for sub-µA systems; not suitable where <1 µs response is required (e.g., fast fault detection). |
Compared with LMV393IDR and TLV3702IPWR, TS862AIPT uniquely balances sub-µA-class power (6 µA), 500 ns speed, rail-to-rail inputs, and push-pull outputs - making it optimal for space- and battery-limited portable safety devices requiring both precision and responsiveness.

FAQ
What is the maximum operating temperature range for TS862AIPT?
The TS862AIPT is specified for operation from -40 °C to +85 °C ambient temperature, validated across this full industrial range with guaranteed electrical performance including input offset voltage, propagation delay, and supply current. Thermal resistance (RθJA) is 120 °C/W in TSSOP8, enabling safe operation up to +85 °C ambient with typical power dissipation below 100 µW.
Does TS862AIPT require external pull-up resistors on its outputs?
No. TS862AIPT features push-pull CMOS outputs capable of sourcing 2.5 mA and sinking 2.5 mA at 2.7 V, delivering VOH ≥ 2.35 V and VOL ≤ 0.45 V. This allows direct connection to 3.3 V or 5 V microcontroller GPIO pins without external pull-up resistors - confirmed in the datasheet Figure 14 and Table 3.
Can TS862AIPT operate from a single 1.8 V supply?
No. TS862AIPT has a minimum supply voltage of 2.7 V, as stated in Table 2 (Operating Conditions) and validated in all electrical characteristics tables (VCC = 2.7 V, 5 V, and 10 V). Operation below 2.7 V is outside specification and may result in undefined output behavior or increased propagation delay.
Is the TS862AIPT pinout compatible with other dual comparators in TSSOP8 packages?
No. TS862AIPT uses a proprietary pinout optimized for dual independent comparators: Pins 1/2/3 serve Comp 1, Pins 6/7/8 serve Comp 2, with shared VCC+ (Pin 5) and VCC− (Pin 4). It is not pin-compatible with LM393 or TLV3702 in TSSOP8 - verified against ST's official package drawing (Figure 27) and pin function table in Section 3.4 of Doc ID 6422 Rev 3.
