TC54VC4202EMB713 is a member of Texas Instruments’ PicoGuard family of supervisor circuits. These circuits provide constant, accurate voltage monitoring and performance supervision for microprocessor-based systems. The TC54VC4202EMB713 is designed with the most modern technologies to provide superior protection and monitoring of the system’s voltage. The device is capable of providing voltage supervision and control with very low power consumption, making it a great choice for battery powered applications.

Application Field

The TC54VC4202EMB713 is ideal for applications where low standby current and constant voltage supervision are needed, such as battery-operated portable devices, industrial equipment, and microprocessor-based systems. The device provides a low standby current of 20µA, enabling it to remain active for longer periods of time and conserving battery life in portable applications. The device comes in a 8-lead Thin Shrink Small Outline Package (TSSOP) and has an operating temperature range of -40°C to +85°C, which makes it well suited for applications in harsh environments as well.

Working Principle

The TC54VC4202EMB713 is a very versatile and user-friendly device for voltage supervision. The device uses an internal Bandgap reference to monitor and supervise system voltage. The reference voltage remains constant regardless of external conditions such as temperature and power supply variance. The device monitors input voltage through the IN pin and provides two output pins, RESET and VOLT, that can be configured to provide monitoring and control in many ways.

The PINs can be configured to work in many ways, including working in conjunction with a timer circuit with a selectable timeout period and programmable reset delay. The device can also be configured to trigger a reset when the input voltage crosses a user-set threshold. It can also be used with a watchdog timer circuit to provide a system “heartbeat”, monitoring the system for proper functioning.

The TC54VC4202EMB713 also has an additional feature called the AUTO mode. In this mode, the device monitors both the input and output voltages and automatically compensates if it detects an input voltage drop. This mode is especially useful for applications where the input voltage may vary significantly, such as when using a system powered by batteries.

Overall, the TC54VC4202EMB713 is a great device for providing accurate voltage supervision and monitoring for microprocessor-based systems. Its versatile features and low power consumption make it especially well suited for battery-operated devices and in harsh environments.
