Product details
Overview
TS9001-2IJ5T from Silicon Laboratories is an ultra-low-power open-drain analog comparator with integrated 1.252 V ±1% voltage reference, guaranteed operation down to +1.6 V supply, 600 nA supply current, and input voltage range extending 200 mV beyond rails. It serves as a precision threshold detector in battery-powered sensing systems where rail-to-rail input tolerance and minimal quiescent power are critical.
For engineers reviewing the TS9001-2IJ5T datasheet, TS9001-2IJ5T pinout, TS9001-2IJ5T application, or TS9001-2IJ5T equivalent, key selection considerations include its open-drain output stage for level-shifting across supply domains, internal 4 mV hysteresis for noise immunity, −40°C to +85°C operating range, SC70-5 package footprint, and compatibility with 2-cell alkaline, NiMH, and Li-ion battery monitoring circuits.
Technical Context
The TS9001-2IJ5T implements a robust input stage tolerant of voltages from VEE −0.2 V to VCC +0.2 V and features internal 4 mV hysteresis to prevent oscillation near trip points. Its open-drain output supports pull-up to voltages up to +6 V relative to VEE, enabling interoperability with higher-voltage logic domains.
It integrates a low-drift 1.252 V reference with 10 ppm/°C max temperature coefficient and 0.2 mVRMS noise (10 Hz–100 kHz, 1 nF bypass), while maintaining 0.1 mV/V line regulation and ±0.2 mV/nA load regulation. Propagation delay is 12 µs (high-to-low) and 21 µs (low-to-high at VCC = 1.6 V, RPULLUP = 100 kΩ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6 V to 5.5 V - enables direct operation from single Li-ion or dual alkaline cells without regulation. |
| Supply Current | 600 nA typical at +25°C - extends battery life in multi-year sensor deployments. |
| Reference Voltage | 1.252 V ±1% - provides stable, factory-trimmed threshold without external components. |
| Input Offset Voltage | 2–10 mV over temperature - ensures accurate trip-point stability in precision detection. |
| Hysteresis | 4 mV internal - eliminates false triggering from EMI or signal noise without external feedback. |
| Propagation Delay | 12 µs (tPD−), 21 µs (tPD+ at 1.6 V) - supports sub-50 kHz event detection in low-power wake-up circuits. |
| Output Leakage | 0.002–1 µA at VO = 5.5 V - preserves pull-up network efficiency in high-impedance interface designs. |
Pinout & Package
TS9001-2IJ5T is housed in a 5-pin SC70 package (JEDEC MO-203 AA), measuring 2.0 mm × 1.25 mm × 0.9 mm, with gull-wing leads and 0.65 mm pitch. The package supports reflow soldering and is lead-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Open-drain output | Sinks current only; requires external pull-up for logic-high assertion; supports voltage translation up to +6 V above VEE. |
| 2 - VEE | Negative supply | Ground reference (0 V typical); defines lower rail for input/output voltage ranges and hysteresis centering. |
| 3 - IN+ | Noninverting input | Accepts signals from VEE −0.2 V to VCC +0.2 V; bias current <1 nA enables high-impedance sensor interfacing. |
| 4 - REF/IN− | Reference output / inverting input | Provides 1.252 V reference for threshold setting; doubles as comparator inverting input when reference is not used. |
| 5 - VCC | Positive supply | Supplies core logic and reference; PSRR of 1 mV/V minimizes supply ripple impact on trip accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 600 nA enables >2.5 million hours of operation on a 2000 mAh AA battery pair (alkaline, 1.8 V cutoff). |
| Rail-to-rail input capability | Inputs tolerate VEE −0.2 V to VCC +0.2 V - eliminates need for external level shifters in ground- or supply-referenced sensing. |
| Integrated voltage reference | 1.252 V ±1%, 10 ppm/°C TC - replaces discrete reference ICs and reduces BOM count in portable threshold detectors. |
| No phase reversal | Guaranteed correct output polarity even when inputs exceed supply rails - prevents erroneous system state transitions. |
| Crowbar-current-free switching | Eliminates supply current surges during output transitions - reduces required bypass capacitance and improves battery efficiency. |
Applications
| 2-Cell Battery Monitoring | Medical Instrument Threshold Detection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9118ASA+ | Same pinout, push-pull output (not open-drain); 1.25 V reference; 1 µA supply current; no internal hysteresis. | Requires external hysteresis network; unsuitable for wired-OR or multi-supply logic interfacing. | Select MAX9118ASA+ only if push-pull drive into CMOS loads is required and external hysteresis is acceptable. |
| TLV3691IDCKR | Open-drain output; 320 nA supply current; no internal reference; 1.8 V min supply; 3.5 mV offset. | Requires external reference; better quiescent current but lacks integrated 1.252 V source for simplified design. | Choose TLV3691IDCKR when lowest possible current dominates and reference can be sourced externally or shared. |
Compared with TS9001-2IJ5T, MAX9118ASA+ offers higher drive strength but lacks open-drain flexibility and built-in hysteresis, while TLV3691IDCKR achieves lower ICC but increases system complexity by omitting the reference - making TS9001-2IJ5T optimal for space- and BOM-constrained battery-monitoring designs requiring self-contained thresholding.

FAQ
What is the maximum allowable voltage on the TS9001-2IJ5T OUT pin?
The TS9001-2IJ5T OUT pin is open-drain and rated for voltages up to +6 V relative to VEE, per Absolute Maximum Ratings. This allows safe interfacing with higher-voltage logic families (e.g., 3.3 V or 5 V MCUs) using an external pull-up resistor, independent of the device's VCC supply level. Exceeding +6 V risks permanent damage.
Does the TS9001-2IJ5T require external hysteresis for stable operation?
No - the TS9001-2IJ5T includes 4 mV of internal hysteresis, sufficient for most low-noise environments. External hysteresis may be added via positive feedback resistors if greater noise immunity is needed, but it is not required for basic functionality. The internal hysteresis eliminates oscillation near trip points without additional components.
Can the TS9001-2IJ5T operate from a single 1.6 V supply?
Yes - the TS9001-2IJ5T is fully specified to operate from +1.6 V to +5.5 V supply (VCC to VEE). At 1.6 V, it delivers 600 nA supply current, 12 µs high-to-low propagation delay, and maintains full input voltage range (VEE −0.2 V to VCC +0.2 V), making it ideal for direct connection to aging alkaline or Li-ion cells.
How is the internal reference used in the TS9001-2IJ5T?
The TS9001-2IJ5T provides its 1.252 V ±1% reference on Pin 4 (REF/IN−), which serves dual function: as a buffered reference output or as the comparator's inverting input. When used as a reference, it drives external circuitry with ≤200 kΩ output impedance and supports capacitive bypassing; when used as IN−, it sets the fixed threshold against which IN+ is compared.
What is the input bias current specification for TS9001-2IJ5T?
The TS9001-2IJ5T has an input bias current of 0.15–2 nA over temperature. This ultra-low value enables direct interfacing with high-impedance sensors (e.g., thermistors, photodiodes) without significant voltage error or loading effects, preserving measurement accuracy in precision threshold detection circuits.
