The TC54VC2902ECB713 is a System Reset Supervisor integrated circuit that provides complete power-on reset capability to ensure that microprocessor-based systems are in a known state during power-up. This circuit provides two basic functions: a reset output and an interrupt input. The reset output latches low whenever the power supply voltage (VCC) drops below a predetermined level, and it can also be activated by an interrupt input when VCC is above this level. The restart of VCC results in the reset output recovering to its inactive high state.

The TC54VC2902ECB713 has a wide range of applications in the aerospace and military industry, as it provides a reliable power-on reset (POR) and allows the system to boot up in a known state. This reset supervisor is integrated with an open-drain active-low reset output, which can handle a wide range of operating voltages from 1.4V to 5.5V. Additionally, the chip can be configured for active-low or active-high reset output. The quick voltage monitoring feature of the circuit enables it to provide reset signals when the power supply gets overloaded and can detect distinct changes in the supply voltage.

The TC54VC2902ECB713 also features an interrupt input, which can be used to trigger a reset output when VCC is above the reset threshold voltage. The interrupt input is active-low and can be triggered by a logic-low input. The circuit also features a wide operating temperature range and a fast response time of 20 µs with a reset pulse width of 200 ms. It has a high reset accuracy, making it suitable for use in highly sensitive systems that require precise reset timing.

The working principle of the TC54VC2902ECB713 is based on a voltage detection circuit connected to the external power supply. The circuit monitors the power supply voltage and automatically triggers a reset output when the voltage level drops below the preset level (VTH). In addition, the active-low interrupt input can also be used to force the reset output to the active-low state even when the power supply voltage is above the VTH level.

The TC54VC2902ECB713 is an ideal choice for microprocessor-based systems that require reliable power-on reset and restart capabilities. Its wide range of applications and features, such as reset accuracy, response time, and operating temperature range, make it an attractive choice for many applications including aerospace and military electronics.

Overall, the TC54VC2902ECB713 is an ideal system reset supervisor integrated circuit that provides reliable power-on reset and restart capabilities, making it suitable for use in a variety of applications in the aerospace and military industry. Its features, including reset accuracy and operating temperature range, make it an attractive choice for many user applications.
