PMIC (power management integrated circuit) supervisors are important components in power management systems, as they provide protection against faults, as well as convenient parameter setting and a variety of interface combinations.

The TC54VN2502ECB713 is a supervisor circuit specifically designed for keeping a microcomputer in reset, combining low-power modules and an adjustable reset delay timer.

This multi-channel supervisor works with a reset input, the VCC pin, and provides multiple functions: active-low reset output, active-high reset output, reference voltage output, and timer delay output. The active-low RESET output is pulled Low momentarily any time the RESET input is pulled High, while the active-high RESET output is pulled High momentarily any time the RESET input is pulled High. The reference voltage and timer delay output pins provide additional convenience. The onboard timer, with a delay adjustable from 0sec to 2.5sec, is intended to be used to delay deassertion of the RESET signal, allowing the microcomputer time for initialization.

The TC54VN2502ECB713 can be employed in automotive, personal electronics, and LED lighting systems, where protection against a variety of faults and powering abnormalities is required. It is ideal for use in embedded systems that utilize a microcontroller while also consuming very low quiescent current. The wide input voltage range (1.2V to 5.5V) and "always on" function make it applicable to a variety of system designs.

In terms of safety and reliability parameters, the TC54VN2502ECB713 offers good immunity to switching transients, allowing for more flexible impedance and noise shielding design. It also features a temperature range from −40 to +85 °C and can provide up to 37mA of active output current, making it suitable for most low-power applications.

In summary, the TC54VN2502ECB713 is a reliable and versatile supervisor IC suitable for a range of applications, offering protection and convenience for microcontroller-based embedded systems, as well as providing high immunity to switching transients and wide operating temperature range.
