Мониторы питания со сторожевыми таймерами
Analog Devices offers a range of supply monitors with watchdog timers. The on-chip watchdog timer can reset the microprocessor if it fails to strobe within a preset timeout period, with multiple reset threshold options available throughout the portfolio. By consuming as little as 3 µA, our supply monitors are suitable for use in low power applications, as well as:
- Automotive infotainment
- Microprocessor systems
- Intelligent instruments
- Supervising DSPs/microcontrollers
- Industrial and portable equipment
- Wireless systems
- Notebook/desktop computers
