X4043PZ-4.5A

Supervisors are power management integrated circuits (PMICs) designed to protect sensitive systems against unexpected power failure. The X4043PZ-4.5A is a PMIC supervisor designed to protect industrial and consumer applications from brown-outs and over voltage conditions. It monitors the supply voltage and if a fault is detected, the X4043PZ-4.5A will control the power supply path to shut down the system safely.

The X4043PZ-4.5A is a programmable supervisor with a wide selection of preset voltage detection levels and programmable reset pulse widths. It contains two independent voltage detection channels, one for monitoring the supply voltage and one for monitoring the system voltage. It has an active low reset output that is triggered when either of the monitoring channels detects an over voltage or brown-out condition. The reset output will remain active until the supply and system voltages return to their normal levels.

The X4043PZ-4.5A is configured using an on-board EEPROM, which allows for easy programming of the device’s threshold and reset pulse width settings. It also has an internal memory that allows the device to self-recover after a fault is detected. The X4043PZ-4.5A also has an open drain output capable of driving an external MOSFET to provide power sequencing control in a system.

The X4043PZ-4.5A is suitable for use in a wide range of industrial, consumer, and automotive applications that require voltage monitoring and protection. It is designed to be used in applications with a wide range of supply voltages, from 3.3V to 28V, making it an ideal solution for many industrial and automotive applications. It is available in a range of packages, from a 4mm x 4mm QFN to a 14-pin SOIC, and is RoHS compliant.

In summary, the X4043PZ-4.5A is a programmable PMIC supervisor designed for use in industrial, consumer, and automotive applications. It features two independent monitoring channels, a wide range of preset voltage detection levels, and programmable reset pulse widths. It is available in a range of packages from 4mm x 4mm QFN to 14-pin SOIC and is RoHS compliant. This makes the X4043PZ-4.5A an ideal device for voltage monitoring and protection.
