Product details
Overview
TLC393CPWRG4 from Texas Instruments is a dual micropower voltage comparator in TSSOP-8 package, featuring 110 µW typical supply power at 5 V, 2.5 µs typical propagation delay (tPLH) with 5-mV overdrive, and single-supply operation from 3 V to 16 V. It delivers rail-to-rail input common-mode range down to −0.2 V and supports open-drain CMOS outputs for flexible interfacing in battery-powered sensing and supervisory circuits.
For engineers reviewing the TLC393CPWRG4 datasheet, TLC393CPWRG4 pinout, TLC393CPWRG4 application, or TLC393CPWRG4 equivalent, this page provides verified electrical specs, temperature-rated performance (0°C to 70°C), LinCMOS™ process advantages including 1.4 mV typical input offset voltage and <1 pA input bias current, and real-world use cases such as motor speed control and supply supervision.
Technical Context
The TLC393CPWRG4 implements two independent comparators using Texas Instruments' LinCMOS™ process, enabling ultra-low power consumption without sacrificing speed or input impedance. Its open-drain output stage requires an external pull-up resistor and supports interfacing with TTL, CMOS, or microcontroller I/O pins across varying supply domains.
Designed as a functional upgrade to LM393, it achieves comparable response time at 1/20th the quiescent power. Input offset voltage remains stable under differential stress up to ±18 V, and common-mode rejection ratio holds ≥84 dB across the full operating temperature range (0°C to 70°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - Enables direct integration into 3.3 V, 5 V, and 12 V systems without level-shifting. |
| Quiescent Supply Current | 22–40 µA (both comparators, 25°C) - Supports multi-year battery life in always-on sensor nodes. |
| Propagation Delay (tPLH) | 2.5 µs typ @ 5-mV overdrive, VDD = 5 V - Sufficient for medium-speed threshold detection in motor control and power sequencing. |
| Input Offset Voltage | 1.4 mV typ (25°C), ≤6.5 mV max (0°C to 70°C) - Ensures accurate trip-point stability in precision voltage monitoring. |
| Input Bias Current | 5 pA typ (25°C), ≤0.6 nA max (70°C) - Minimizes error in high-impedance sensor interfaces (e.g., thermistors, photodiodes). |
| Common-Mode Input Range | −0.2 V to VDD − 1.5 V - Allows inputs below ground (e.g., current-sense shunt monitoring) and near VDD. |
| Output Type | Open-drain CMOS - Permits wired-OR logic, mixed-voltage interfacing, and programmable pull-up voltage selection. |

| 3 | IN1+ | Non-inverting input of comparator 1 - Accepts signals from −0.2 V to VDD − 1.5 V. |
| 4 | GND | Analog/digital ground reference - Must be low-impedance; decoupling capacitor recommended. |
| 5 | VDD | Positive supply rail - Supports 3 V to 16 V; internal ESD protection rated to 2000 V. |

|---|---|
|
Use Scenario: Monitoring Li-ion cell voltage during charge/discharge cycles in portable medical devices. IC Role / Device Role / Timing Role: Dual comparator detects upper (4.2 V) and lower (2.8 V) thresholds to trigger charge enable/disable and low-battery warning. Use Value: 110 µW quiescent power extends runtime; rail-to-rail input accommodates shunt-based sensing below ground. |
Use Scenario: Generating PWM duty cycle in brushed DC motor driver for HVAC actuators. IC Role / Device Role / Timing Role: One comparator compares ramp oscillator voltage against setpoint; second validates direction logic. Use Value: 2.5 µs propagation delay ensures tight PWM timing control; open-drain outputs interface directly with half-H drivers (e.g., SN75603). |
| Power Supply Supervisor | Two-Phase Clock Generator |
|
Use Scenario: Providing reset assertion and early power-fail warning for microcontrollers in industrial PLCs. IC Role / Device Role / Timing Role: First comparator monitors 5 V rail for brownout; second watches 12 V rail for pre-fail indication. Use Value: Stable 6.5 mV max input offset ensures consistent trip points across 0°C–70°C; CMRR ≥84 dB rejects supply ripple. |
Use Scenario: Generating non-overlapping clock phases for synchronous buck converter gate drivers. IC Role / Device Role / Timing Role: Two comparators form relaxation oscillator with precise dead-time control via RC network. Use Value: Low input bias current prevents timing drift in high-value RC networks; dual independent channels simplify layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Higher supply current (500 µA typ), slower response (tPLH ≈ 1.5 µs min but with higher power), no LinCMOS™ input stability. | Suitable for cost-sensitive, non-battery applications where power >100 µA is acceptable. | Select LM393DR only when legacy compatibility or lower unit cost outweighs micropower and precision requirements. |
| TLC3702CDR | Push-pull (not open-drain) outputs, higher supply current (120 µA typ), wider VDD range (3 V–16 V), same LinCMOS™ input specs. | Preferred when active-high outputs or elimination of external pull-ups is required in digital logic interfaces. | Choose TLC3702CDR when system design mandates push-pull drive without external components, accepting higher quiescent current. |
Compared with LM393DR and TLC3702CDR, the TLC393CPWRG4 uniquely balances ultra-low power (22 µA), precision (1.4 mV VIO), and open-drain flexibility-making it optimal for battery-constrained, high-accuracy threshold detection where external pull-up control is advantageous.

FAQ
What is the maximum input voltage range for TLC393CPWRG4?
The TLC393CPWRG4 supports a common-mode input voltage range from −0.2 V to VDD − 1.5 V at 25°C, and 0 V to VDD − 1.5 V across its full operating temperature range (0°C to 70°C). This allows inputs below ground (e.g., for current-sense amplifiers) and near the positive rail. Absolute maximum differential input voltage is ±18 V, and input voltage must remain within −0.3 V to VDD to avoid forward-biasing ESD diodes.
Does TLC393CPWRG4 require external pull-up resistors on its outputs?
Yes, TLC393CPWRG4 features open-drain CMOS outputs (OUT1 and OUT2), which require external pull-up resistors to define the high-level voltage and sink current. Typical values range from 2.2 kΩ to 10 kΩ depending on rise time and load requirements. The device itself does not provide internal pull-ups, and omitting them results in undefined high-state behavior.
What is the operating temperature range specified for TLC393CPWRG4?
The TLC393CPWRG4 is characterized for the commercial temperature range of 0°C to 70°C. This rating is confirmed in the datasheet's "recommended operating conditions" table and applies to all electrical specifications unless otherwise noted. It is distinct from the extended industrial (TLC393I) or automotive (TLC393Q) variants.
How does the LinCMOS™ process benefit TLC393CPWRG4 in precision applications?
The LinCMOS™ process used in TLC393CPWRG4 delivers extremely stable input offset voltage (<6.5 mV max over temperature), ultra-low input bias current (<0.6 nA at 70°C), and high common-mode rejection (≥84 dB). These traits minimize measurement error in high-impedance sensor interfaces and ensure reliable threshold detection across voltage and temperature variations-key for battery monitors and supply supervisors.
Can TLC393CPWRG4 replace LM393 in existing designs?
TLC393CPWRG4 is pin-compatible with LM393 in SOIC-8 and TSSOP-8 packages and shares identical pinout and basic functionality. However, due to its significantly lower supply current (22 µA vs. ~500 µA) and improved input specs, layout changes may be needed for decoupling and thermal management. System validation is recommended, especially for timing-critical or high-precision uses where the enhanced performance alters behavior.
