Collective electronic power management (PMIC) - Supervisors can be broadly classified into two main types: functional supervisors and sequencing supervisors. TC54VN3502EZB is a sequencing supervisor and can be used in any applications requiring a supervisor chip. This article will examine the application field and working principle of the TC54VN3502EZB.

The TC54VN3502EZB is a multi-purpose, peak current sensing power management supervision device that is suitable for any popular voltage supervisor applications. It can be used as a supply voltage monitor in many consumer and industrial applications, such as medical, automotive and computing systems. It can even be utilized in portable applications, providing an accurate and reliable voltage monitoring system, which helps protect the system from damaging current overshoots.

The TC54VN3502EZB provides three operational modes: Manual Reset, Auto Reset, and \'Utility Mode\'. In Manual Reset mode, the reset pin is manually asserted to reset after a certain time period. In Auto Reset mode, the supervisor instantly asserts a reset signal when the supply voltage is under the trip point. In Utility Mode, the supervisor chip can be used to monitor the internal temperature of the system, and is often used in devices such as laptops and embedded systems.

The operating principle of the TC54VN3502EZB is the same for all of its operating modes: it receives a power supply voltage input and runs through an internal voltage monitor circuit. This voltage monitor circuit triggers a reset signal when the monitored voltage dips below the pre-set threshold level. The duration of the reset signal is determined by the reset timeout. This timeout can be adjusted via an external resistor or capacitor, allowing users to tailor the length of the reset signal to their particular application.

The TC54VN3502EZB is manufactured using a 0.35-micron CMOS process and ESD protection. It operates across the entire range of supply voltages, from 1.8V to 5.5V. The supply current consumption of the chip is low, with a maximum of only 33uA when in reset mode and maximum of only 800uA when in active mode.

The TC54VN3502EZB can be used in many types of applications. It is often used as a supply voltage monitor in computer systems and also in embedded systems as a temperature monitor. It is also used in automotive electronics, such as power window control, for monitoring and reporting the voltage level of the supply voltage. Furthermore, it is also useful in various medical applications, such as in glucose meters and other medical equipment.

In summary, the TC54VN3502EZB is a sequencing supervisor that can be used in any applications requiring a supervisor chip. It is manufactured using a 0.35-micron CMOS process and ESD protection and operates across the entire range of supply voltages, from 1.8V to 5.5V. Its supply current consumption is very low, with a maximum of only 800uA when in active mode. It can be used in many types of applications, such as in computer systems, embedded systems, automotive electronics, and medical devices.
