S-80917CNMC-G8MT2U

The S-80917CNMC-G8MT2U is a device from the Picor brand of PMIC (Power Management Integrated Circuit) Supervisors. These Power Management Integrated Circuits are designed with the purpose of providing an efficient and cost-effective way of monitoring and controlling power circuits. Power-related circuits such as battery charging, protections, and system reset are usually supervised by these supervisors. This particular model supplies an accurate and fast system reset under voltage lockout condition, along with several other features that make it highly effective for its purpose.

The S-80917CNMC-G8MT2U is designed for use in Lithium Ion battery charging and protection applications. In these applications, the supervisor monitors the voltage on a particular power supply to determine if the voltage is within acceptable ranges. If the voltage is too high or too low, the supervisor kicks in to initiate a system reset so as to protect the components connected to the power source. This supervisor also includes eFuse and cycle-by-cycle current limit protections, so as to prevent the associated power sources from being damaged.

The S-80917CNMC-G8MT2U implements a wide operating range that allows it to be used in various environments. It is rated for operation from 2.5V to 3.8V, making it suitable for use in 1S and 2S battery pack protection circuits. It also features a wide operating temperature range, from -40 °C to 85 °C, which makes it ideal for use in a range of applications that demand higher temperatures. The supervisor\'s integrated 32kHz oscillator also allows it to be used at frequencies up to 100 kHz, which is suitable for regulating fast-charging battery packs.

The S-80917CNMC-G8MT2U employs a range of technologies for efficient operation. It features a proprietary charge protection scheme and a VCC clamp protection circuit, allowing it to detect input/output voltage over/under voltage and reduce internal power source dissipation during system reset. The supervisor also includes a comparator that can detect an under-voltage condition to initiate a system reset. Additionally, it includes a programmable timer which makes it possible to adjust the reset timeout period to the user\'s specifications.

The S-80917CNMC-G8MT2U also includes a wide array of protection features to safeguard against various power supply-related issues. It includes both input and output overvoltage protection circuits, in addition to input undervoltage and overcurrent protection. Its integrated programmable temperature tolerant shutdown circuit is able to shut down the device and prevent it from over-heating under extreme temperatures. It also features a turn-on safe timer, which delays the reset from occurring in order to allow the power supply to become stable.

In summary, the S-80917CNMC-G8MT2U is an ideal PMIC (Power Management Integrated Circuit) supervisor for Lithium Ion battery charging and protection applications. Its wide range of features allow it to reliably monitor and protect the associated power sources, as well as provide an accurate and fast system reset under voltage lockout conditions. Its wide operating range also allows it to be used in various environments, while its proprietary charge protection scheme and VCC clamp protection circuit make it highly effective in providing protection against input/output voltage over/under-voltage and reduce internal power source dissipation during system reset.
