S-80828CLMC-B6NT2U

The S-80828CLMC-B6NT2U is a power supply supervisor IC (PMIC - Supervisors). The device provides supply voltage monitoring, reset/power-fail/power-good management, as well as I2C-bus communications functions. Different from similar ICs with the same functions, the S-80828CLMC-B6NT2U supports a wide operating temperature range from -40°C to +125°C, and it also has an integrated temperature measurement unit. This makes the device ideal for use in harsh environments.

Application Field

The S-80828CLMC-B6NT2U is a feature-rich device and is suitable for a wide variety of applications, such as automotive, industrial, communication and consumer systems. It\'s compatible with 3.3V/5V power supply systems and is designed to ensure the stability of the power supply. It can also be used to monitor several power rails, output power good, initialize power-on reset for the system, protect wrong voltage input, detect over/under voltage, detect excess over/under temperature and etc...

Working Principle

The S-80828CLMC-B6NT2U has 6 pins, of which P1 and P2 are supply voltage pins, P3 is RESET pin, P4 and P5 are the Serial Adress Input and Serial Data Input respectively, and P6 is GND. Once powered up, the S-80828CLMC-B6NT2U measures the supply voltage and will reset the system if the voltage falls below a predefined level. The device also has an on-chip temperature measurement unit and will reset the system if the system temperature is too high. P3 is an open drain output which can be used to signal the power good status or monitor the standby voltage. P4 and P5 can be used to receive data from external devices via I2C-bus.

Conclusion

The S-80828CLMC-B6NT2U is an integrated power supply supervisor IC with wide operating temperature range. It provides features to ensure the stability of power supply, such as voltage monitoring, reset/power-fail/power-good management and I2C-bus communications. The device is suitable for various applications like automotive, industrial, communication and consumer systems.
