Microchip Technology, Inc. PMIC - Supervisors TC32MCDB713

The TC32MCDB713 is a 3-pin system supervisor designed to enhance the reliability of microprocessor-based systems. It integrates essential functions such as power-on reset control, a watchdog timer, and an external reset override in a compact SOT-223 package. This device ensures stable operation by holding the processor in a reset state for a minimum of 500 milliseconds during power-up, preventing unstable operation due to power fluctuations. The watchdog timer monitors the microprocessor's activity, issuing a reset if the processor fails to respond within a specified timeout period, typically 700 milliseconds. The output can be wire-ORed with a manual reset switch, allowing for easy system reset and contact debounce functionality. The TC32MCDB713 operates within a temperature range of 0°C to +70°C and supports supply voltages from 4.5V to 5.5V, making it suitable for various applications, including battery-powered devices, automotive systems, and embedded controllers.
