The S-80137BLPF-JEWTFG IC is a PMIC Supervisors, which is designed to provide monitoring and protection of microprocessors in a wide range of applications.

The S-80137BLPF-JEWTFG has a wide input voltage range and is rated up to 12V, making it suitable for a variety of standard voltages as well as low-voltage microprocessors. Additionally, it includes a programmable detect voltage, a programmable threshold voltage, and a programmable delay time.

In terms of operation, the S-80137BLPF-JEWTFG detects a system imbalance caused by either a supply failure or an over- or undervoltage. When it detects the failure, it triggers an active low output that can be used to trigger a reset initiator, such as an alarm or a power switch. The active low output is also connected to the open circuit detect (OCD) pin to ensure reset of the microcontroller when the supply fails.

The S-80137BLPF-JEWTFG can also be used to detect the undervoltage condition in order to shut down the system safely. To do this, the S-80137BLPF-JEWTFG must be connected to the microcontroller. When the voltage falls below the threshold voltage, it triggers an active low output, which is also connected to the OCD pin.

Besides, the S-80137BLPF-JEWTFG also has an internal hall effect-based guard pin which monitors the external current. This pin can be used to detect a battery discharge or reverse polarity, and initiate a system shutdown. It can also be used to detect changes in load current, such as when a relay turns on or off, and trigger a reset.

The S-80137BLPF-JEWTFG is ideal for a wide range of applications where monitor and protection of a microcontroller is required. For example, it can be used to provide over/undervoltage protection in industrial applications and automotive applications, as well as to provide advanced features such as short-circuit, reverse polarity, and overcurrent protection.

In addition, it can also be used in mobile applications where it can help to protect the mobile device against external power glitches. It also has the ability to detect input voltage and shut down the system in case of undervoltage conditions.

Overall, the S-80137BLPF-JEWTFG is a reliable and versatile PMIC Supervisor, with a wide input voltage range, a programmable detect voltage, and a programmable threshold voltage. It is ideal for providing monitoring and protection for microprocessors in a wide range of applications, from industrial and automotive, to mobile and consumer, making it a great choice for all types of designs.
