Application Fields

The NCV304LSQ42T1 is mainly used to detect, control, reset and monitor the status of power supplies. It is designed to improve system reliability, minimize risk of system failure, and reduce cost. Additionally, it can be used in ATE systems, digital equipment, embedded systems, and automotive applications. The NCV304LSQ42T1 also offers high integration and ease of use in applications for Industrial Automation, Building Automation, Data and Network Security applications.

Working Principle

The working principle of the NCV304LSQ42T1 is based on the power supply monitor and power failure detection. The power supply monitor constantly monitors the input voltage levels, ensuring that it remains within the operating range. If the voltage drops below the lower or rises above the upper voltage thresholds, the chip generates an output signal which triggers the power-failure interrupt signal.

The power failure detection monitors the input voltage levels and detects a sudden drop in the supply voltage. When the voltage drops, a signal is sent out to trigger reset. The integrated reset signal can be routed to drive the system reset line directly, or it can be used to issue an interrupt signal which will enable other components of the system, such as a microcontroller, to take proper action.

The analog sensor monitoring enables the chip to monitor analog signals, such as temperature and supply voltage. If the conditions are not conducive, it will send out an alarm or trigger reset. The clock monitor monitors the operation of the system clock, and will detect wrong frequencies or missing clock warnings. The window watchdog provides the capability to detect timing failures of the microcontroller, by setting two separate window intervals.

The dual timer feature allows realization of precise duration and delay timing with separate start and stop signals. This feature can be used to reduce power consumption by allowing the system to switch to sleep/idle modes in order to meet the energy efficiency requirements.
