X40010S8-AT1

The X40010S8-AT1 is a supervisory circuit from the PMIC manufacturers, which integrates a watchdog, Voltage Monitors and a Reset into one chip. It ensures that the functions of a device, system, or circuit are performing within various acceptable operating parameters. In this article, we will discuss the application fields, working principle and features of the X40010S8-AT1.

Application Field

Because the X40010S8-AT1 is a reset and supervisory circuit, it has a lot of applications in embedded systems, computers, consumer electronics, automotive electronics, communications, industrial controls and so on. The X40010S8-AT1 is especially suitable for devices that requires power-on reset and regular monitoring, such as microcontrollers, FPGAs, GPUs, and ASICs.

Working Principle

The X40010S8-AT1 monitors the supply voltage, temperature and other power signals of the embedded device, and periodically outputs a watchdog timer reset. The core operating principle of the X40010S8-AT1 is that it monitors the power conditions of the device, and if it detects any abnormal condition, it will output a reset signal to restart the device or system, thereby ensuring that the system or device is performing within certain acceptable parameters.

The X40010S8-AT1 is equipped with 3 power monitoring pins and an active low reset output pin. When the supply voltage and other power signals are abnormal, the X40010S8-AT1 will quickly output a reset signal, and keep it active until the abnormal condition is removed. The X40010S8-AT1 also includes a programmable watchdog timer to monitor the system or device performance, and output a reset signal when a system crash is detected.

Features

The X40010S8-AT1 has various features for improved performance. First of all, the X40010S8-AT1 has an operating voltage range of 1.8V to 5.5V, so it is suitable for a wide range of applications. The X40010S8-AT1 has 7 selectable reset thresholds and 8 watchdogs ranging from 1.0 msec to 128.0 seconds, so that it can be tuned to fit the needs of different systems and devices. Next, it has various voltage rails for monitoring, like VBATT, VCC, VSEN, and VDD. Last but not least, it has a self-test feature that ensures that it is running normally, even in dynamic operating conditions.

In conclusion, the X40010S8-AT1 is a supervisory circuit from the PMIC manufacturers, which integrates a watchdog, Voltage Monitors and a Reset into one chip. It has many applications in embedded systems, computers, consumer electronics, automotive electronics, communications, industrial controls and so on. The X40010S8-AT1 has various features for improved performance such as a wide operating voltage range, 7 selectable reset thresholds, 8 watchdogs and self-test feature.
