Product details
Overview
LMV393IDDURG4 from Texas Instruments is a dual low-voltage comparator IC designed for precision voltage comparison in space-constrained, battery-powered systems. It operates from 2.7V to 5.5V, draws 50μA typical supply current, features rail-to-rail input common-mode range including ground, and delivers 150mV typical output saturation voltage with open-collector outputs - enabling flexible logic-level interfacing in server PSU monitoring circuits.
For engineers reviewing the LMV393IDDURG4 datasheet, LMV393IDDURG4 pinout, LMV393IDDURG4 application, or LMV393IDDURG4 equivalent, key selection criteria include its dual-channel open-drain architecture, −40°C to +125°C operating temperature, SOIC-8 package compatibility, and verified performance at both 2.7V and 5V supply rails.
Technical Context
The LMV393IDDURG4 implements a PNP-input differential pair enabling input common-mode operation down to ground (VICR = −0.1V to VCC−0.7V), critical for single-supply 3.3V/5V systems. Its open-collector NPN output stage supports wired-AND logic and external pull-up voltage translation up to 5.5V.
Propagation delay is supply- and overdrive-dependent: at VCC = 2.7V and 100mV overdrive, tPHL = 350ns and tPLH = 400ns; at VCC = 5V and same overdrive, tPHL = 200ns and tPLH = 300ns. Input offset voltage remains ≤7mV (typ) across −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V - supports direct integration into 3.3V and 5V logic domains without level-shifting circuitry. |
| Supply Current (typ) | 50μA - enables multi-year battery life in portable vacuum robots and cordless power tools. |
| Input Offset Voltage (max) | 9mV over −40°C to +125°C - ensures reliable threshold detection in factory automation sensors. |
| Output Saturation Voltage (typ) | 150mV at 1.5mA sink - guarantees clean logic-low signaling even under moderate load conditions. |
| Propagation Delay (tPHL) | 200ns at 5V/100mV overdrive - meets timing requirements for fast-response PSU fault detection. |
| Common-Mode Input Range | −0.1V to VCC−0.7V - allows direct sensing of ground-referenced signals like battery voltage or motor current shunts. |
| ESD Rating (HBM) | ±2000V - provides robustness during automated PCB assembly and field handling. |
Pinout & Package
LMV393IDDURG4 is housed in an 8-pin SOIC (D) package measuring 3.91mm × 4.90mm, with standard JEDEC MS-012AC footprint and RoHS-compliant NiPdAu lead finish. Thermal resistance RθJA = 168°C/W enables operation up to +125°C ambient without forced airflow.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Open-collector output of Comparator 1 - requires external pull-up to define logic-high level and sink current when IN1− > IN1+. |
| 2 | IN1− | Inverting input of Comparator 1 - accepts reference or feedback signal; common-mode range includes ground. |
| 3 | IN1+ | Non-inverting input of Comparator 1 - connects to sensed voltage (e.g., battery terminal or sensor output). |
| 4 | GND | Analog ground reference - must be low-impedance and separated from noisy digital return paths. |
| 5 | VCC+ | Positive supply pin - requires 0.1μF bypass capacitor to GND for stable high-speed operation. |
| 6 | IN2+ | Non-inverting input of Comparator 2 - used for independent second threshold (e.g., overvoltage and undervoltage detection). |
| 7 | IN2− | Inverting input of Comparator 2 - pairs with IN2+ to form second independent comparison channel. |
| 8 | OUT2 | Open-collector output of Comparator 2 - enables dual-threshold monitoring with shared or separate pull-ups. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-ground input common-mode range | Enables direct interface with 0V-referenced sources (e.g., current-sense resistors, thermistors) without level-shifting components. |
| Open-collector outputs | Supports wired-AND logic, mixed-voltage interfacing (e.g., 3.3V comparator driving 5V MCU interrupt), and configurable pull-up voltage. |
| Low quiescent current (50μA typ) | Reduces standby power in always-on building automation controllers and extends runtime in portable appliances. |
| Wide temperature range (−40°C to +125°C) | Validates reliable operation in automotive cabin modules, industrial motor drives, and outdoor server enclosures. |
| Fast propagation delay (200ns @ 5V) | Meets real-time response requirements for overcurrent protection in cordless power tool battery packs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Wider supply range (2V–36V), higher ICC (500μA typ), no guaranteed ground-sensing capability below 1.5V common-mode. | Suitable for industrial 24V systems but less optimal for 3.3V battery monitoring due to input range limitation. | Select LM393DR only when legacy 24V designs require drop-in replacement and ground-referenced inputs are not required. |
| TLV3702IDR | Lower ICC (8μA typ), rail-to-rail inputs, push-pull output (no external pull-up needed), but higher VIO (3.5mV max) and cost. | Better for ultra-low-power IoT nodes; push-pull eliminates pull-up resistor but prevents wired-AND functionality. | Choose TLV3702IDR when minimizing component count and leakage current outweighs need for open-collector flexibility. |
Compared with LM393DR and TLV3702IDR, LMV393IDDURG4 uniquely balances ultra-low power (50μA), true ground-sensing input, open-collector versatility, and SOIC-8 manufacturability - making it the optimal choice for cost-sensitive, space-constrained 3.3V/5V embedded comparators where wired-AND or mixed-voltage interfacing is required.

FAQ
What is the maximum supply voltage rating for LMV393IDDURG4?
The absolute maximum supply voltage for LMV393IDDURG4 is 5.5V, as specified in Section 5.1 of the datasheet. Operation beyond this voltage risks permanent device damage. For reliable long-term use, the recommended operating range is 2.7V to 5.5V, with stable performance confirmed at both 2.7V and 5V nominal supplies. LMV393IDDURG4 must never be subjected to transient spikes exceeding 5.5V on the VCC+ pin.
Does LMV393IDDURG4 support input voltages at ground potential?
Yes, LMV393IDDURG4 supports input common-mode voltages down to −0.1V (with margin), explicitly enabling direct connection to ground-referenced signals such as current-sense resistors or thermistor dividers. This capability is enabled by its PNP-input stage and is validated across −40°C to +125°C. At 25°C, the common-mode range is −0.1V to 2.0V at 2.7V supply and −0.1V to 4.2V at 5V supply - confirming true rail-to-ground operation.
What is the typical output saturation voltage of LMV393IDDURG4 and how does it affect design?
LMV393IDDURG4 delivers 150mV typical output saturation voltage (VSAT) when sinking 1.5mA at 25°C. This low VOL ensures reliable logic-low recognition by downstream 3.3V or 5V MCUs, even with modest pull-up resistances. Designers must verify that actual sink current - determined by pull-up voltage and resistance - does not exceed 23mA (absolute max) while maintaining VOL within system noise margins. Figure 5-3 in the datasheet provides VOL vs. IOUT curves for precise sizing.
Can LMV393IDDURG4 outputs be wire-OR'd together?
Yes, LMV393IDDURG4's open-collector outputs are expressly designed for wired-AND (commonly misnamed wire-OR) configurations. Connecting OUT1 and OUT2 to a shared pull-up resistor creates a logical AND function: the combined node goes low only if either comparator asserts. This is widely used in power-good sequencing and fault-bus architectures. Ensure total sink current remains within 23mA per output and that pull-up voltage does not exceed 5.5V.
What package and footprint does LMV393IDDURG4 use?
LMV393IDDURG4 uses the standard 8-pin SOIC (D) package with 3.91mm × 4.90mm body dimensions and 1.27mm lead pitch, fully compatible with JEDEC MS-012AC. Its markings "MV393I" appear on the top surface, and it features NiPdAu lead finish with Level-1 moisture sensitivity (MSL-1, unlimited floor life). This package supports automated pick-and-place and reflow soldering per IPC-J-STD-020.
