PMIC - Supervisors

The S-1000N34-I4T1G PMIC Supervisor is a highly featured PMIC supervisor used to monitor, protect and provide power supply to microprocessors and digital circuits. It is a low-power, single-supply, low-quiescent current device with a precision voltage monitor, reset and power supply sequencing to provide power supply supervisions and system resets.

Application Field

The S-1000N34-I4T1G PMIC Supervisor is ideal for various microprocessor-based or digital-circuit based designs such as computer systems and consumer electronic equipment. Its wide operating range from 0.9V to 5V allows for usage in a broad range of applications. Additionally, its robust output for reset and power-on sequencing helps to reduce the risk of data corruption and system failure.

Working Principle

The S-1000N34-I4T1G PMIC Supervisor contains an advanced precision voltage monitor (POVM) along with a reset circuit. The POVM monitors an on-chip voltage with a ±50mV accuracy range over a wide input range of 0.9V to 5V. The POVM generates a reset signal when the power supply drops below the programmable threshold voltage. Additionally, the reset circuit provides a power-on reset (POR) and time delays to provide power-on sequencing.

The S-1000N34-I4T1G PMIC Supervisor also features an open drain reset output, allowing designers more flexibility when creating their own reset schemes. With an active low RESET pin and an active high RESET pin, designers can have the best of both worlds when it comes to reset functionality.

The S-1000N34-I4T1G PMIC Supervisor also has low quiescent current, making it suitable for low power applications. It supports a wake-up voltage threshold detection that is adjustable from a low of 1V to a high of 4.85V. This allows designers to adjust the reset threshold based on their specific application requirements.

Conclusion

The S-1000N34-I4T1G PMIC Supervisor is ideal for use in microprocessor-based or digital-circuit based designs. The wide operating range, power-on reset and time delays, open drain reset output and adjustable wake-up voltage threshold detection will help designers achieve the safety and reliability they seek in their designs.
