PMIC, or power management integrated circuit, is a type of integrated circuit designed to regulate and control power. Supervisors, as one of the important building blocks of power management, are used to provide robust power-on reset and system reset functions for a variety of electronic products. The S-80956CNPF-G9STFG is a Type 1 compliant power-on supervisors with its UL recognized insulation system, combined with the intelligent auto reset circuit and overtemperature protection, provides stable and reliable power-on reset and system reset function onto any serious of system applications. The S-80956CNPF-G9STFG is designed to be used in consumer electronics, communication systems, industrial system and automation, medical, military and aerospace applications.

The S-80956CNPF-G9STFG is an active low 3-pin device featuring a voltage monitor circuit, reset generator and clock generator in a very small package. The reset generator includes an active low reset output as well as an active high manual reset input. The device monitors the system supply voltage, VCC, and when the voltage drops below the preset threshold, VTH, a reset output signal will be generated to reset the system. When the voltage VCC rises above the VTH, reset signal returns inactive and system is running again. There is also an additional pin, VDD, which is connected to a low voltage supply and controls the reset response times.

The S-80956CNPF-G9STFG provides an open drain reset signal, which allows several units in series to be tied together for a longer reset signal. The device also features superb mid-frequency noise immunity which is critical for low VCC operation. And the small package makes the S-80956CNPF-G9STFG capable of being placed on densely populated surfaces with extremely small board area requirements.

The S-80956CNPF-G9STFG provides a voltage monitor circuit with wide power supply voltage range from 1V up to 5.5V, which makes it ideal for multiple supply voltage low voltage applications. The voltage monitor circuit contains programmable VCC trip voltages and reset thresholds, which makes it an ideal substitute to a wide range of supervisors in the market.

The reset generator of the S-80956CNPF-G9STFG includes an active low reset output and an active high manual reset input. When the VCC voltage drops below the preset trip point, VTH, the reset generator will send an active low reset signal. The reset pulse has a fixed width and duration, and is long enough to reset most of the CMOS logic circuits. The active high manual reset input is used to override the reset circuit and initiate a system reset at any time. This feature is especially useful for systems requiring manual reset or system setup and calibration.

The S-80956CNPF-G9STFG also provides an overtemperature reset protection. This is designed to protect the system from thermal runaway in highly unforeseen conditions. The overtemperature protection circuit monitors the temperature of the device and initiates a system reset once the temperature of the device exceeds a preset point. This ensures the system runs reliably with no risk of damage.

The clock generator of S-80956CNPF-G9STFG has a wide adjustable frequency range from 0.25MHz up to 3.2MHz. This allows the device to sync with most frequency dependent circuits and facilitate system reset operations when required. The device also has frequency synchronization built-in, which allows multiple S-80956CNPF-G9STFG devices to be used together and synchronized in timed cycles.

The S-80956CNPF-G9STFG is a Type 1 compliant power-on supervisors, combined with its UL recognized insulation system, intelligent auto reset circuit and overtemperature protection, provides a stable and reliable power-on reset and system reset solution to a wide range of system applications. With its wide adjustable voltage monitor and reset threshold, wide input supply voltage range, ultra-small package, robust design and high noise immunity, the S-80956CNPF-G9STFG is an ideal choice for any system requiring a stable and reliable power-on reset and system reset operation.
