概述

Description

LM393LVQDRQ1 is TI’s low-voltage, dual comparator in an 8-pin package. It provides two independent comparators with open-collector outputs, suited for fast, low-power level sensing in battery-powered and mixed-signal apps.
Key features:
- Supply voltage: 2.7 V to 5.5 V (LV variant)
- Input common-mode: from ground to about Vcc − 1.5 V
- Outputs: open-collector; each channel must have a pull-up resistor to Vcc
- Low power; suitable for portable devices
Typical applications:
- Battery-powered sensors, zero-crossing detectors, window/level detectors, MCU interface circuits
How to use:
- Connect Vcc and GND
- Apply signals to the + and − inputs
- Add pull-ups on both outputs; outputs switch low when V+ > V− (for standard operation)
Package/ordering:
- 8-pin device; QDRQ1 denotes TI’s specific package variant. Check the datasheet for exact pinout, thermal, and framing details.

Features

Here are the key features of LM393LVQDRQ1 (dual low-voltage comparator):
- Dual differential comparators with open-collector outputs
- Input common-mode range includes the negative rail (ground)
- Outputs can only sink current; requires external pull-up resistors
- Low-voltage variant: typical supply range around 2.7 V to 5.5 V
- Low power consumption suitable for battery-powered designs
- Wide operating temperature range (industrial: typically -40°C to 125°C)
- Available in compact packaging (8-pin packages)
- Suitable for level detection, zero-crossing, window comparison, and related applications
Note: For exact electrical parameters (supply current, propagation delay, sink current, etc.), please refer to the datasheet for your specific package variant.

Package

LM393LVQDRQ1 is in a VQFN-8 package (Very Thin Quad Flat No-Lead, 8 pins).

Pinout

- Pin count: 8 pins (8-pin package)
- Function: Dual low-voltage voltage comparator with open-collector outputs; each comparator compares two inputs (non-inverting and inverting) and sinks current on its output when V+ > V− (requires external pull-up resistors).

Manufacturer

The LM393LVQDRQ1 is manufactured by Texas Instruments Incorporated (TI). TI is an American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits, sensors, and related products for a wide range of industries.

Application

LM393LVQDRQ1 is a low-voltage, dual open-collector comparator. Common applications:
- Battery and power-supply supervision (under/overvoltage, window detect)
- Zero-cross and level detection
- PWM/ramp comparison for motor control and DC-DC converters
- Current sensing with pull-up resistor
- Alarm, watchdog, and protection circuits
- Sensor interfacing and simple wired-OR logic with microcontrollers
