S-1009C15I-I4T1U Working Principle

The S-1009C15I-I4T1U is a single-cell voltage supervisor that operates on a precision bandgap reference. It provides monitoring of the applied input voltage, overvoltage protection, and secure power-off control. The S-1009C15I-I4T1U voltage supervisor contains a precision bandgap reference, a low-power comparator, an adjustable delay timer, and an overvoltage detection comparator. The precision bandgap reference provides stability of the comparator threshold voltage over varying process and temperature conditions. The low-power comparator compares the applied input voltage with the reference provided by the onboard bandgap. When the applied voltage is equal to or greater than the reference voltage, the power-good output turns on. The adjustable delay timer triggers after the power-good output has turned on, and provides delay before the power-on reset signal is generated. The overvoltage detection comparator monitors the applied input voltage. When the input voltage exceeds a preset level, the comparator triggers an overvoltage event and shuts down the output.

Conclusion

The S-1009C15I-I4T1U PMIC - Supervisors provides robust and reliable protection with its advanced circuit design and precise reference bandgap. The monitoring and protection features make the S-1009C15I-I4T1U a suitable solution for a wide range of applications, from customer electronics to industrial and medical applications.
