Description

The UTC 82CXX series is a family of 3-terminal voltage detectors that are fabricated using CMOS technologies with low power consumption and high accuracy. The UTC 82C381 is one of the members of this series and comes with highly precise detection voltage which drifts minimally with temperature changes.

Specifications and features

• High-accuracy detection voltage: ±2%
• Detect voltage range: 0.9V to 6.2V in 0.1V increments
• Detect voltage temperature characteristics: TYP. ±100ppm/°C
• Wide operating voltage range: 0.7V to 10.0V
• Low current consumption: TYP 0.7μA (at VIN=1.5V)

Application Scenarios

The 82C381 is widely used in various applications that require low power consumption, accurate and stable voltage detection, such as:

• Battery-powered devices
• Power management systems
• Portable devices
• Automotive electronics
• Industrial control systems

Comparison

• High-accuracy voltage detection
• Wide voltage detection range with small increments
• Low power consumption
• Minimal temperature drift

• The UTC 82C381 does not provide overvoltage detection or under-voltage lockout functionality
• This model may not be suitable for applications that require high accuracy and stability with voltage outputs greater than 6.2V
