X4163PIZ-4.5A

PMIC (Power Management Integrated Circuit) is considered a type of safety device. It is used to monitor, control, and manage voltage inputs. A Supervisory is a part of the circuit designed to ensure the correct operation of a system or a device.

The X4163PIZ-4.5A is a single voltage detector PMIC Supervisor that features a programmable delay, active-low or active-high output, adjustable reset or watchdog timeout, built-in thermal protection, and adjustable reset threshold. This device is designed to monitor and control a 4.5V power supply, but can also be used for other applications.

X4163PIZ-4.5A Application Field:

• Microcontroller-based System Reset
• Safety Alarms
• Battery Protections
• Telecommunication Systems
• Automobile Electronics
• Portable Consumer Electronics

X4163PIZ-4.5A Working Principle:

The X4163PIZ-4.5A is a single-voltage detector PMIC supervisor that consists of a high-performance voltage detector followed by a programmable reboot delay, reset or watchdog timeout, and active-low or active-high output. It is designed to detect a power supply failure and assert a reset or watchdog signal to ensure reliable system operation.

When the voltage on the VCC pin drops below the preset reset trigger threshold, the supervisor will activate. This will assert a reset signal with a programmable delay. When the power supply is in the proper range, the supervisor will not assert any reset signal. The reset signal can be set as active high or active low when required.

The reset timer output has a programmable delay for up to 1024ms with a 1 ms resolution. To build a watchdog function, the device has an adjustable reset timer from 2ms to 4096 ms with a 4 ms resolution. Both reset timer and reset timeout can be disabled when not needed. For safety, the X4163PIZ-4.5A has a built-in thermal protection to prevent the device from an excessive temperature.

In summary, the X4163PIZ-4.5A is a single-voltage detector PMIC supervisor designed for 4.5V power supply. It is used to detect a power supply failure and provide a reset signal to ensure reliable system operation with adjustable reset trigger threshold, reset timer, reset timeout. It also has a built-in thermal protection to prevent the device from an excessive temperature.
