A PMIC Supervisor, or voltage supervisor, provides a low-cost protection for electronic systems and a failsafe power reset sequence. The MIC809SYC3 is a low-power reset and supply supervision device used to protect embedded micro-controllers. This device provides reliable power controllers and reset sequences, allowing systems to recover from operational faults and to provide over-current protection. It provides a reliable, low-cost power reset and supply supervision.

Overview of the MIC809SYC3 PMIC Supervisor

The MIC809SYC3 is a high-efficiency supply supervisor device used for reset and power controller for embedded control systems. It can monitor power inputs and provide automatic reset and power control sequence when the power supply deviates from the set safety margins. This device features a low quiescent current of 10 μA with an active-high reset signal. It has an operating temperature range from -40 to 125°C. This makes it ideal for use in harsh industrial environments.

Features of MIC809SYC3 PMIC Supervisor

• Low power consumption with a quiescent current of 10 μA.
• Temperature range of -40 to 125°C.
• Active-high reset signal.
• Robust electrostatic discharge (ESD) protection.
• Automatic power distribution, enabling more efficient use of current.
• VCC supply voltage range of 1.6V to 5.5V.
• Programmable reset timeout.

Applications of MIC809SYC3 PMIC Supervisor

The MIC809SYC3 voltage supervisor is suitable for a variety of applications. It can be used to protect against short-circuit or over-current conditions, by protecting against excessively low or high power inputs, or resetting microprocessors and DSPs. It can monitor power inputs and provide automatic reset and power control sequences for embedded control systems. Other applications include power distribution networks, power converters, and motor control systems.

Working Principle of MIC809SYC3 PMIC Supervisor

The MIC809SYC3 supervisor monitors the input power supply and detects when the supply deviates from the set safety margins of operating parameters. When the supply deviates from the set safety thresholds, the device will reset the system. This will reset the microcontroller, DSP or other system components, allowing the system to recover from operational faults and to provide over-current protection. The device also provides automatic power distribution, enabling more efficient use of current.

The MIC809SYC3 supervisor also features a programmable reset timeout. This allows users to determine how long the reset signal should stay active before it is deactivated. This timeout can be programmed with a capacitor connected to the CAP pin.

Conclusion

The MIC809SYC3 is a low-power reset and supply supervision device used to protect embedded micro-controllers. It features a low quiescent current of 10 μA with an active-high reset signal and an operating temperature range from -40 to 125°C. This makes it ideal for industrial environments. Its application includes protection against over-current and short-circuit conditions, as well as resetting microprocessors, DSPs and other system components. It also provides automatic power distribution and a programmable reset timeout.
