The DS1812-10+T from Maxim Integrated is a robust, precision microprocessor (µP) supervisory circuit designed to monitor the power supplies in µP and digital systems. It provides a precise, cost-effective system for managing power supply and battery control functions in a range of electronic applications.
Key Features
- Voltage Monitoring: This device ensures that the microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. It monitors the supply voltage and keeps the µP in reset until that voltage reaches a stable operating level and remains there for a predetermined time period.
- Accuracy: The DS1812-10+T has a factory-trimmed reset threshold, which provides high accuracy and eliminates the need for external components.
- Low Power Consumption: It is designed for low power consumption, making it suitable for battery-powered applications.
- Temperature Range: The device operates over a wide temperature range, from -40°C to +85°C, enabling its use in various environmental conditions.
- Package: Available in a compact, 3-pin TO-92 package, the DS1812-10+T is designed for space-constrained applications.
