TC54VN3002EZB713

PMIC (power management integrated circuits) are integrated circuits that are designed to provide sophisticated power management functionality for electronic devices and systems. Supervisors are an important type of PMIC that is designed to supervise power supplies and perform reset functions based on supply and system conditions. One example of a Supervisor is the TC54VN3002EZB713.

The TC54VN3002EZB713 is a high-performance and cost-effective VCC (power supply) supervisor which is particularly well suited for use in low-power applications. The device provides reset and reset enable outputs that can be used to monitor the operation of power supply rails. The reset enable output is asserted when the RESET input is de-asserted, allowing the supervisor to be used in a variety of applications. The device can be used to monitor two voltage sets, one of which is accessible on a standard VCC pin.

TC54VN3002EZB713 has several application fields, including state monitoring, supply monitoring, safety device monitoring, voltage monitoring, and level detection/protection. It can be used in systems that require supply monitoring and reset after a power up or power down, level detection/protection from under or over voltage input and output ranges, or emergency shut down in the event of a power failure. Additionally, the supervisor can be used to monitor supply states in hand-held systems or for other embedded applications.

The main principle of TC54VN3002EZB713 is based on the monitoring of the VCC supply voltage and the asserting of a reset when the voltage drops below the reset threshold voltage. The device has a programmable reset threshold between 0.1V and 3.6V and an adjustable hysteresis when the voltage falls below the reset threshold. Additionally, the device has a separate input pin to allow the reset output to be disabled to allow system power-up and power-down sequencing. The reset output is asserted low when either the VCC voltage or the RESET input pin is below the reset threshold and the reset enable pin is asserted high.

In addition to providing reset and reset enable outputs, the TC54VN3002EZB713 also has two built-in N-channel MOSFETs that can be used for power switch control. The MOSFETs can be used to control the power to an ASIC or other device, allowing the supervisor to be used as an alternative to a system-level power switch. The MOSFETs can also be used to sequentially energize each power rail in the system, assuring that all the components in the system are powered up at the same time.

Overall, the TC54VN3002EZB713 is a highly versatile device designed for use in a variety of low-power applications. It provides reset and reset enable outputs that can be used to monitor the operation of power supplies, as well as two built-in MOSFETs for power switch control. This device is an ideal solution for systems that require supply monitoring and reset after a power up or power down, level detection/protection from under or over voltage input and output ranges, or emergency shut down in the event of a power failure.
