Product details
Overview
TS3011IYQ3T from STMicroelectronics is a rail-to-rail input, high-speed comparator with 8 ns propagation delay, 470 μA typical supply current at 5 V, and operation from 2.2 V to 5 V across –40 °C to 125 °C. It features push-pull output, built-in 2 mV hysteresis, and automotive qualification (AEC-Q100) for on-board chargers and telecom signal conditioning.
For engineers reviewing the TS3011IYQ3T datasheet, TS3011IYQ3T pinout, TS3011IYQ3T application, or TS3011IYQ3T equivalent, key selection criteria include propagation delay vs. overdrive, rail-to-rail input common-mode range (–0.2 V to VCC+0.2 V), output drive capability (64 mA sink/source at 5 V), and DFN8 2×2 wettable flanks package for automated optical inspection.
Technical Context
The TS3011IYQ3T implements a high-gain, low-offset comparator core with internal hysteresis (2 mV) to prevent oscillation near threshold. Its input stage supports rail-to-rail common-mode voltage from (VCC– – 0.2 V) to (VCC+ + 0.2 V), enabling direct sensing of battery voltages or DAC outputs without level-shifting.
Push-pull output delivers full rail swing - VOH = 4.84 V (min, 4 mA source, 5 V supply), VOL = 90 mV (typ, 4 mA sink) - eliminating external pull-ups and simplifying interface to MCU GPIOs or logic gates. Propagation delay remains stable across temperature (6–11 ns at 50 mV overdrive, VCC = 5 V) and supply voltage (2.2–5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 8 ns typ. at 50 mV overdrive, VCC = 5 V - enables sampling of >100 MHz signals in high-speed data acquisition. |
| Supply current | 470 μA typ. at 5 V - supports always-on monitoring in battery-powered instrumentation with <1 μA standby when disabled. |
| Input offset voltage | ±7 mV max (–40 °C to 125 °C) - ensures reliable detection of small analog thresholds (e.g., 10 mV battery fault flags). |
| Common-mode range | VCC– – 0.2 V to VCC+ + 0.2 V - accepts inputs down to ground or up to supply rail, eliminating need for bias resistors. |
| Output drive | 64 mA sink/source (min) at 5 V - directly drives LEDs, MOSFET gates, or 50 Ω transmission lines without buffering. |
| Hysteresis | 2 mV built-in - suppresses chatter on noisy inputs (e.g., motor current sense, relay feedback) without external components. |
| ESD rating | 2 kV HBM / 200 V MM - meets industrial I/O robustness requirements without additional protection circuitry. |
Pinout & Package
TS3011IYQ3T is packaged in DFN8 2×2 mm with wettable flanks (exposed pad optional to ground), optimized for automated optical inspection and thermal performance (RTHJC = 26 °C/W). Pin functions are validated per DS8604 Rev 9 Figure 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 6, 7 | No-connect (NC) | Unused terminals; must be left floating or tied to ground per layout guidelines - no electrical function. |
| 5 | VCC+ | Positive supply input - requires local 100 nF + 10 nF + 1 nF decoupling per application note to maintain 8 ns timing stability. |
| 8 | VCC– | Negative supply input (GND reference) - connects to system ground plane; low-inductance path critical for noise immunity. |
| OUT | Output | Push-pull digital output - drives high/low actively; compatible with 1.8 V, 3.3 V, and 5 V logic families without level shifters. |
| IN+ | Non-inverting input | Rail-to-rail analog input - accepts signals from 0 V to VCC+ + 0.2 V; 1 pA bias current minimizes loading on high-Z sources. |
| IN– | Inverting input | Rail-to-rail analog input - matched to IN+ for precision differential sensing; 5 µV/°C offset drift ensures stability over temperature. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Supports direct interface to sensors, DACs, and battery monitors without external biasing or level-shifting networks. |
| 8 ns propagation delay | Enables real-time overvoltage/undervoltage detection in fast-switching power converters (e.g., GaN-based OBCs). |
| 470 μA supply current at 5 V | Reduces quiescent power in always-on monitoring circuits - e.g., 12 V to 5 V buck converter supervision draws <2.4 mW. |
| DFN8 2×2 wettable flanks | Enables solder joint inspection via AOI and improves thermal dissipation (RTHJA = 57 °C/W) in compact automotive modules. |
| AEC-Q100 Grade 1 qualified | Validated for automotive applications including on-board chargers, battery management systems, and ADAS power rails. |
Applications
| On-Board Charger (OBC) Supervision | High-Speed Data Acquisition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3501DBVR | 1.9 ns propagation delay, but 2.5 mA supply current - 5× higher quiescent power than TS3011IYQ3T. | Optimized for ultra-high-speed test equipment; unsuitable for battery-powered or thermally constrained OBC modules. | Select when speed >5 ns is mandatory and power budget allows ≥2 mA per channel. |
| MAX961ESA+ | 4.5 ns delay, ±1.5 mV offset, but only 2.7–5.5 V operation and no AEC-Q100 qualification. | Lacks automotive qualification and rail-to-rail input - requires input biasing for ground-referenced signals. | Prefer for industrial bench instruments where qualification and rail-to-rail input are non-critical. |
Compared with TLV3501DBVR and MAX961ESA+, TS3011IYQ3T uniquely balances nanosecond-speed response (8 ns), micropower operation (470 μA), rail-to-rail input, and AEC-Q100 compliance - making it optimal for space- and power-constrained automotive and portable systems requiring robust, low-latency threshold detection.

FAQ
What is the maximum operating supply voltage for TS3011IYQ3T?
The absolute maximum supply voltage (VCC) is 5.5 V, but the device is specified for reliable operation from 2.2 V to 5.0 V. Operation above 5.0 V risks exceeding safe junction temperature and invalidates AEC-Q100 qualification - sustained use at 5.5 V is not recommended.
Does TS3011IYQ3T require external hysteresis resistors?
No. The TS3011IYQ3T integrates 2 mV of internal hysteresis, eliminating the need for external positive feedback resistors. This simplifies PCB layout, reduces component count, and ensures consistent hysteresis across temperature and process variation.
Can TS3011IYQ3T drive a 50 Ω transmission line directly?
Yes. With 64 mA sink/source capability at 5 V, the push-pull output can drive a 50 Ω load to within 120 mV of rail (VOL = 120 mV max at 4 mA sink), supporting clean 100 Mbps LVDS-like signaling without external buffers - verified in DS8604 Figure 6–9.
Is the exposed pad on the DFN8 package electrically connected?
No. The exposed pad on TS3011IYQ3T's DFN8 2×2 package is thermally conductive but electrically isolated. Per DS8604 Rev 9 Figure 2, it may be left floating or connected to ground for improved thermal performance - no electrical connection to internal circuitry exists.
