RTC Module With CPU Supervisor
The BQ4847YMT is a microprocessor-based system reset IC from Texas Instruments. It is a 28-pin DIP package with a wide operating temperature range of -40°C to +85°C. The BQ4847YMT is designed to monitor power supply voltages, temperatures, and other system parameters. It provides a reset signal to the microprocessor when any of the monitored parameters exceed their programmed thresholds. The reset signal is active low and is asserted for a minimum of 140ms. The BQ4847YMT features an adjustable reset threshold voltage, adjustable reset timeout, and adjustable reset delay. It also features an adjustable reset hysteresis voltage, adjustable reset timeout, and adjustable reset delay. The reset signal is active low and is asserted for a minimum of 140ms. The BQ4847YMT is suitable for use in a wide range of applications, including embedded systems, industrial control systems, and automotive systems. It is also suitable for use in applications where a reset signal is required to protect the system from overvoltage, overcurrent, and over temperature conditions. (For reference only)
