S-80155CLMC-JJGT2U

The S-80155CLMC-JJGT2U is a high-performance supervisor integrated circuit (IC) combining two independent voltage supervisors, programmable reset generator and edge detector timer. It is manufactured by Sii Semiconductor Inc. and is part of the PMIC (Power Management ICs) product line from the company. The device is compliant with the JEDEC Standard DC Characteristics for Class I Devices and meets the most stringent requirements for system stability and reliability.

The S-80155CLMC-JJGT2U is used in a variety of applications because of its added features, including automated reset and reconfiguration of single-event latch assembles (SELAs), additional independent voltage monitoring, and integrated true-time-delay reset generation. In addition, this device features an adjustable reset timeout which helps preventing erroneous cycles due to power supply transients. The S-80155CLMC-JJGT2U is suitable for use in embedded controller systems and system on chip (SoC) applications, such as gateways, routers, and servers.

The S-80155CLMC-JJGT2U is composed of two independent voltage supervisors, an edge detector, a programmable reset generator, an overvoltage lockout and an error-output circuit. The two independent voltage supervisors feature external set-up of trip points for single/dual voltage monitoring, open/short fault detection, input voltage range up to 30V, and an accuracy of up to ±100mV. One of the supervisors can enable or disable the reset output by pulling the reset enable pin low or high, respectively.

In terms of working principle, the S-80155CLMC-JJGT2U has three primary functions. First, it monitors any existing positive voltage supply applied to the voltage input pin. Whenever the voltage falls below the set trip point, the voltage supervisor de-asserts the reset output, activating the reset timeout timer. When the timeout is reached, the device will generate a reset signal, normally resetting any system controller. Second, it monitors a negative supply voltage input, enabled by the negative voltage enable pin. When the voltage falls below the set trip point, the device will generate a reset. Lastly, the S-80155CLMC-JJGT2U performs automated reset and reconfiguration of SELAs for under/over/reset sequences.

In conclusion, the S-80155CLMC-JJGT2U from Sii Semiconductor Inc. is a versatile and highly reliable PMIC device suitable for embedded controller systems and SoC applications. Its integrated voltage supervisors, programmable reset generator, and edge detector timer provide the necessary prerequisites for system reliability and performance in a power-savvy and optimized design package.
