The X4283P-2.7A is a supervisor chip from the family of power management integrated circuits (PMICs). It is a single-channel, ultra-low power, micro-power supervisor chip with features and protections ideal for monitoring system operation power on reset (PWRON), voltage supervisors, programmable time delays, and low-voltage detection. The X4283P-2.7A has been used in various systems and applications in a wide range of markets, including automotive, industrial control, electronic white goods, set-top boxes, portable media players, and many more applications. It has an operating temperature range of -40°C to +85°C.

The X4283P-2.7A has two main functions: voltage monitoring and PWRON reset. It uses a voltage monitor to detect when power supply voltages fall below predetermined levels. When the voltage falls below the set threshold, the X4283P-2.7A issues a reset signal, which causes the system to be reset. The X4283P-2.7A also provides a PWRON reset which is active when power is first applied. This allows for orderly system initialization.

The X4283P-2.7A has several features which make it suitable for use in various applications. It has an open-drain, active-low RESET output which is capable of driving an interrupt or ASIC mode control line. This feature ensures that the reset signal is propagated to any downstream ICs in the system. In addition, the X4283P-2.7A has an integrated watchdog timer, which allows for system timeouts to be detected. This ensures that the system keeps running properly and doesn’t enter an uncontrolled state.

The X4283P-2.7A also has an adjustable reset threshold which can be set, using external resistors, to match the operating voltage of the system it is being used in. In addition, the X4283P-2.7A has an adjustable reset delay and a selectable power-on reset hold-off time. These features allow for customization of the system’s reset response. This allows for minimal power consumption and maximized system integrity.

The X4283P-2.7A is an ideal device for monitoring and protecting against power supply problems in system applications. Its low power and adjustable features make it suitable for applications such as voltage monitoring, power up resetting, watchdog timer, and low voltage detection. It is easy to use, reliable, and cost-effective, making it a perfect solution for supervisors in any system that requires dependable power management.
