Power management integrated circuits (PMICs) have become increasingly important as they help control, monitor and manage the use of power in modern electronics. They are designed to provide optimal performance whilst exhibiting low power consumption and heat dissipation.

One type of PMIC is the supervisory device, which is responsible for monitoring and controlling the supply voltage levels for the device. It is typically embedded along with the power regulator and provides the basic services that an integrated circuit requires from its power supply.

The S-1003NA35I-M5T1U is an ultra-low power Microcontroller Supervisor with advanced reset circuitry. The device provides a number of benefits, including no minimum reset cycle, adjustable reset trippoints, a +200ms reset window, over-voltage and under-voltage lockout, and low power consumption of typically 175nA in normal operation. It also features an automatic reset pulse stretching and is available in a tiny SOT-23-5 package.

The primary application of this device is in microcontroller-based systems that require an efficient and reliable reset source. It provides an ideal solution for those applications in which space is limited and low power consumption is desired.

The S-1003NA35I-M5T1U works by monitoring the input voltage, VIN, and then triggering an active low signal, RESET, to the microcontroller when it drops below a preset threshold. The device is capable of alerting the microcontroller before it powers down or crashes due to a voltage low event. The microcontroller can then take corrective action, either simply restarting or other corrective measure.

The S-1003NA35I-M5T1U also enables the user to adjust the trip point of the reset monitoring by changing the values of resistor R1 and R2, which are connected to the RESET pin. By increasing or decreasing the resistance of each resistor, the user can increase or decrease the voltage threshold at which the RESET pin is activated.

The S-1003NA35I-M5T1U is a reliable, low power and low cost solution for microcontroller-based systems that require reset/supervisor capabilities. The device not only provides a reliable reset source for microcontrollers, but also offers a range of adjustable parameters that allow users to tailor the device for their specific application. It is ideal for use in consumer electronic products, medical instruments and other related applications.
