The S-80826CNPF-B8LTFU is a supervisory IC used widely in power management systems. It can provide multiple voltage monitoring, power-on reset signal, manual reset signal, and power-on reset signal with adjustable discharging delay time. It also has an independent WDI output. All this in an ultra-low power, tiny 4-pin SOT-23 package.

In terms of its application fields, the S-80826CNPF-B8LTFU is mainly used in automotive products, industrial control systems and other high reliability sectors. It takes advantages of its miniaturization and integration, which help to reduce areas, cost and installation work. Besides, it does not need additional external components and requires just a very small board for the connection. In addition, its excellent ESD conceptual design can well protect it from static electricity.

In terms of its working principle, the S-80826CNPF-B8LTFU is a very sensitive voltage supervisor. Its operating voltage range is between 2.6V to 5.5V while its detection voltage range is between 1.6V to 5.5V. Its detection accuracy is up to ±1.5%, and its ultra-low power consumption is typically 7uA. Its maximum reset output delay time can be up to 3.2ms, and its WDI output will be active when the voltage of its voltage input port is higher than the preset threshold.

The WDI output of the S-80826CNPF-B8LTFU is designed based on the open drain output, so this requires an external pull-up resistor. It also has high accuracy manual reset input. To put it simply, when the manual reset input is triggered so the output will be active and it also includes a low-voltage reset status flag. And as for the power-on reset signal, its discharging delay time can be adjusted from 0ms to 3.2ms.

In conclusion, the S-80826CNPF-B8LTFU is a PMIC - Supervisors which can provide multiple voltage monitoring, power-on reset signal, manual reset signal, and power-on reset signal with adjustable discharging delay time. It has been widely used in automotive products, industrial control systems and other high reliability sectors. Its operating voltage range is between 2.6V to 5.5V while its detection voltage range is between 1.6V to 5.5V. Its detection accuracy is up to ±1.5%, and its ultra-low power consumption is typically 7uA. Its maximum reset output delay time can be up to 3.2ms, and it can provide a high accuracy manual reset and WDI output with external pull-up resistor.
