Description

LMV393DR2G is Texas Instruments’ dual low-power voltage comparator in an 8-pin DR2G (VSSOP) package. It is designed for battery-powered and low-voltage sensing applications.
Key points:
- Dual comparator with single-supply operation (typical 2.7–5.5 V)
- Features low quiescent current and rail-to-rail inputs (allows sensing near ground and up toward Vcc)
- Packaged in an 8-pin DR2G VSSOP for compact boards
Common uses:
- Threshold and window detectors
- Level sensing and comparisons for microcontroller interfaces
- Battery monitoring and simple zero-cross / timing circuits
Note: refer to the datasheet for exact electrical specs (input common-mode range, output behavior, propagation delay, and supply current) and recommended operating conditions.

Features

Here are the typical features of the LMV393DR2G (TI LMV393 family):
- Dual, low-power comparators in one package
- Open-drain outputs (requires pull-up resistors)
- Input common-mode range includes ground
- Wide supply voltage range: generally 2.7 V to 5.5 V
- Low input bias current and low input offset for accurate thresholds
- Fast response/k favorable propagation delay for small-signal sensing
- Small 8-pin DR2G package (compact footprint)
- ESD protection on input pins (robust to handling)
Note: for exact electrical specs (offset, bias, delay, and temperature range), please consult the TI datasheet for LMV393DR2G.

Package

LMV393DR2G comes in an 8-pin small-outline package (SOIC-8), RoHS-compliant.

Pinout

- Pin count: 8 pins (8-pin package in LMV393DR2G).
- Function: Dual voltage comparator (two comparators in one package) with open-collector outputs (requires pull-ups). Used to compare two input voltages and produce a logic-level output.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational semiconductor company that designs and manufactures analog, mixed-signal ICs and embedded processing solutions; one of the world’s largest semiconductor firms.

Application

LMV393DR2G is a dual, low-power voltage comparator. Typical applications:
- Battery-powered voltage monitoring and undervoltage protection
- Window detectors to keep a signal within a defined range
- Zero-cross/level detection for AC, PWM, and switching circuits
- Sensor conditioning (thermistors, photodiodes, Hall sensors) with thresholding
- Microcontroller reset/monitor circuits with external pull-ups
- Hysteresis to prevent chatter in noisy environments
- Reference/threshold detectors in DC–DC converters and power-management circuits

Equivalent

Closest direct equivalent: TI TLV393 (dual, low-voltage comparator from the same family as LMV393). Other vendors offer similar low-voltage dual comparators (e.g., Microchip MCP6561/6562), but pinouts and specs may differ. For exact cross, use a cross-reference/search tool from the supplier.
