The S-80819CLNB-B6ET2G is a microcontroller supervisor device in the PMIC - Supervisors product family from its manufacturer, ROHM Semiconductor. This device is designed to provide voltage monitoring and reset functions for microcontrollers and system designs. This device integrates a voltage detector, POR (power on reset), an independent delay timer, and a reset output. It is designed to provide system reset and delay features in response to various conditions such as an over-voltage or undershoot condition on the supply lines.

The S-80819CLNB-B6ET2G offers a wide operating voltage range with its ultra-low supply current. It also has a wide monitoring range with over-voltage detection from 6V up to 42V. The POR reset output is available in the active low or active high logic level with an adjustable threshold. The adjustable reset delay timer provides a key feature in providing protection to microcontrollers against voltage transients, while the fast response time of the reset output ensures a maximum reset hold time.

The S-80819CLNB-B6ET2G can be used in various applications such as power supplies, microcontrollers, digital signal processors and system monitoring. In addition, this device provides an internal watchdog timer (WDT) to support system resets when there is an occurrence of a possible fault or system malfunction. Furthermore, it provides a warning output that can be used to signal an external system in the event of an over-voltage condition.

The working principle of the S-80819CLNB-B6ET2G is as follows: first, it monitors the input voltage for over-/under-voltage conditions. When an over- or under-voltage condition is detected, the device will set an internal reset flag and the POR output will be set. The POR output is an active low or active high logic level with an adjustable threshold. Additionally, the adjustable delay timer will delay the reset output for an adjustable amount of time before it sets the POR output to its inactive state. The reset is held until the voltage condition is removed and the reset flag is cleared.

Furthermore, the S-80819CLNB-B6ET2G has an integrated watchdog timer which can be used in applications that require a reset signal after a programmed time interval. This feature helps detect latches and help prevent system malfunctions. The device also features a warning output that can be used to signal an external system when an over-voltage condition has been detected. This output can be used to shut down a portion of a system to prevent further damage.

Overall, the S-80819CLNB-B6ET2G is an ideal solution for applications which require voltage monitoring and reset functions for microcontrollers and system designs. This device is an efficient and cost-effective solution for protecting microcontrollers from over-/under-voltage conditions and system malfunctions. It has a wide monitoring range with over-voltage detection from 6V up to 42V and provides an integrated watchdog timer, warning output and adjustable delay timer for system reset when necessary.
