Applications
1. Battery-Powered Devices
Portable electronics (e.g., smartwatches, wireless earbuds)
loT sensor nodes
Low-power devices like e-cigarettes and glucose meters
2.Power Management
Voltage monitoring (overvoltage/undervoltage protection)
Power switching control (e.g., automatic battery/USB switching)
Low-battery detection (for rechargeable devices)
3. Consumer Electronics
Touch key detection
Signal threshold detection (e.g. audio signal triggering)
Electronic toys, remote controls
4. industrial Control
Window comparators (for voltage/current monitoring)
Overcurrent protection in motor control
Sensor signal conditioning (e.g., temperature, light intensity
detection)
5. Automotive Electronics
12V/24V system voltage monitoring
Headlight/fan control
Vehicle sensor interfaces
andnbsp;
Description
These devices consist of a low-power voltage comparator designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic where the input common-mode voltage range includes ground, even though operated from a single power supply voltage.
