S-80130BLPF-JEPTFG Integrated Circuits (ICs)

PMIC, or Power Management ICs, are gaining increasing presence in systems today. Supervisory Circuits, having roles as voltage monitors, system resetters, and other protections embedded in them, have seen sweeping growth ever since the expanding of processor and memory applications. With higher needs for stability, the demand for reliability and safety-related performances soar.

S-80130BLPF-JEPTFG is a state-of-the-art supervisor circuit widely used in computing, telecom, industrial and gaming applications. The device is an ultra-low-power monolithic CMOS supervisor with dual supervisory inputs, independently programmable reset timeout values, and push/pull or open-drain reset timeout output. The supervisor has dual active-high reset outputs driven by two independent voltage monitors.

The S-80130BLPF-JEPTFG is well suited for applications where maximum reliability is required. The supervisor issues an active-high reset at power up, power down or on detection of an extreme process variation due to either a slow settling power supply or an excessive voltage on a power rail. Its features and low power consumption make it an excellent solution for a wide range of automotive, industrial, gaming and computing applications.

Working Principle

The S-80130BLPF-JEPTFG uses an advanced adaptation of the standard low-power CMOS detection technique to accurately monitor and control the power-on reset of its outputs. It contains an independent voltage reference, current sources and multiple control circuitry, capable of detecting and responding to both rising and falling edges of the monitored input. The power-on reset of the outputs occurs if either one of the selected threshold boundaries (above or below) is reached. An active-high reset is issued when the output is asserted or reset depending on the reset polarity settings.

When power is first applied, an active-low, push/pull or open-drain output is issued to indicate the power-on reset. The S-80130BLPF-JEPTFG resets its outputs when either of the two monitored power rails reaches the threshold set by the two independent voltage monitors at the selected threshold level. An active-high, push/pull or open-drain reset is issued to indicate the reset occurred. Additionally, the S-80130BLPF-JEPTFG features a unique feature called Input Timeout that allows it to reset and trip an alarm if either input monitor remains active for a period of time greater than the selected timeout period. This feature eliminates chances of excessive voltage or current spikes on either power rail resulting in potential damage to system components or irrecoverable data losses.

The S-80130BLPF-JEPTFG’s ultra-low-power operation and reliable reset operation ensure a high level of system stability and performance and make it the perfect choice for a wide range of industrial and computing applications.

Features

The S-80130BLPF-JEPTFG provides several features that extend its functionality and provide added system stability and performance. These features include:

• Unique dual supervisory input for each independent voltage monitor
• Independent voltage monitor selectable voltage and reset timeout with push/pull or open-drain reset timeout output for each monitored input
• Delayed power-on reset and input timeout
• Programmable reset indication output
• Programmable reset timeout period
• Programmable reset protection against false tripping
• Low power consumption
• Compact 8-pin, surface mount package

The combination of multiple features packed into a small package gives S-80130BLPF-JEPTFG superior advantages over similar sized low-power supervisors.

Applications

The S-80130BLPF-JEPTFG is an ideal supervisor solution for computing, industrial, telecom and gaming applications. Applications such as handheld mobile devices, notebooks, desktops and servers, storage systems and power supply systems, as well as industrial process control systems, all require reliable power supply stability and reset protection.

The S-80130BLPF-JEPTFG provides both the low power and reliable reset protection these systems need to ensure uninterrupted operation and system reliability. Its small package size and wide operating temperature range make it well-suited for a wide range of applications. With its multiple features and ultra-low-power operation, S-80130BLPF-JEPTFG is the perfect choice for low power processors and memory systems.
