Power management integrated circuits (PMICs) are frequently used in system designs. PMICs can monitor and control power to increase system reliability and performance. Supervisors, a type of PMIC, allow customers to implement higher system reliability and higher levels of integration than in analog-only solutions. S-80151ANPF-JDCTFG is a supervisor from Seiko Instruments. It monitors critical input voltages and protects a system from unsafe voltages and/or other conditions.

The S-80151ANPF-JDCTFG is a highly integrated supervisor featuring independently configurable programmable thresholds, independent reset and power supply signals, an internal voltage reference, and an adjustable reset timeout period. The unit is designed to provide a variety of applications with user-defined thresholds to protect the system from abnormal conditions. The device is rated for operation from 2.25V to 5.5V, and can be used in applications up to 6V.

The S-80151ANPF-JDCTFG includes programmable delay times for reset processing, allowing for a more flexible power-on reset system. The delay times range from 1 ms to 1 s and the delay time can be adjusted by the length of the external capacitor. It also features a manual reset input, a watchdog timer, and an adjustable undervoltage lockout detection type that can prevent system restarting when the voltage falls below a user-defined level.

The S-80151ANPF-JDCTFG has wide operating temperature range support between -40°C and 105°C. The device also has ESD protection of the 7.5 kV contact discharge and the 15 kV human body model so that systems employing S-80151ANPF-JDCTFG are robust to electrostatic discharges. The S-80151ANPF-JDCTFG is rated for a minimum pulse width of 1 μs, a maximum supply current of 5 μA, and a maximum output current of 15 mA.

S-80151ANPF-JDCTFG potential applications includes powering microcontrollers and processors in IoT, industrial, home appliance, medical and automotive applications. The device can be used to efficiently protect systems from abnormal conditions, and its adjustable delay times allow for a more precise timing of reset processing and system start-up. Therefore, the S-80151ANPF-JDCTFG can provide an excellent solution for wide range of power management applications.

The S-80151ANPF-JDCTFG uses an internal voltage reference and comparator to continuously monitor the two external input voltages. When the voltage of one of the inputs exceeds the trip point set by the user, it forces the RESET and / or PWRGD outputs to activate. The reset input is also monitored, so if a manual reset is commanded, the RESET output is activated. The power supply is monitored by the PWRGD output and is used to monitor the power-up sequence of the system. Once the input voltage rises above the normal operating level, the PWRGD output activates, indicating that the power supply is stable.

In conclusion, the S-80151ANPF-JDCTFG supervisor is a feature-rich, highly integrated product that provides users with robust system protection and reliable power-up operation. It offers adjustable reset timeouts, adjustable under-voltage lockout, and wide temperature operation, making it suitable for use in many applications. The device meets the challenging demands of users in a wide variety of industries and is equipped with the tools to provide a secure and reliable system for any system design.
