The S-1009N16I-I4T1U is a supervisory device in the Power Management IC (PMIC) family. It is an advanced single-time-supervisory circuit in an industry-standard, small form package. It operates over an extended temperature range and has an integrated power-on reset (POR). This POR provides a reliable system reset on power up, preventing system start-up from illegal or unknown states. It is available in a range of operating voltages, making it ideal for automotive, industrial and communication systems applications.

The S-1009N16I-I4T1U is a low-cost and low-power device, ideal for resource-constrained systems design. It features an integrated voltage comparator and a variety of reset outputs. Its robust construction and flexible configuration options make it a popular choice for automotive, industrial and general PCB designs. This device provides a variety of reset outputs, making it suitable for a range of different applications.

The S-1009N16I-I4T1U can be used to monitor reset conditions in systems ranging from microcontrollers to large microprocessors, DSPs and other processing devices. It monitors the power supply voltage for the system, and when the condition is detected, it initiates a reset to return the system to a known or safe state. This prevents the system from entering into an unknown or illegal state due to erratic power supply voltages.

The working principle of the S-1009N16I-I4T1U is based on a voltage reference circuit. This circuit includes an external and internal voltage reference, which are compared to an adjustable threshold voltage set by a resistor and the output is used to generate a reset pulse. When the voltage of the system falls below the threshold voltage, an internal reset signal is generated, which then triggers a reset. This reset pulse resets the system to a known state.

The device also features additional features, such as a watchdog timer and delay settings. The watchdog timer monitors the system and issues an interrupt if the operation fails to complete within a certain period of time. The delay settings allow the user to adjust the latency between the power-on reset and the reset pulse. This feature is important for managing the system operations and preventing the system from entering into an unknown or illegal state.

The S-1009N16I-I4T1U offers a wide range of application fields and is extensively used in automotive, industrial, communications, and general PCB designs. The device can monitor and detect reset conditions in systems ranging from microcontrollers to large microprocessors, DSPs and other processing devices. It also provides several reset output pins, allowing it to be easily configured for different applications. In addition to acting as a reset generator, it can also serve as a power monitoring device.

The S-1009N16I-I4T1U can be used for general system reset, for critical functional operations, for power saving purposes, for managing system operations and for preventing ambiguous operation. It is a low-cost and low-power device, making it ideal for resource-constrained systems design. It is available in an industry-standard, small form factor and is perfect for any system design that requires a reliable reset circuit.
