The S-1003NA50I-M5T1U is an advanced supervisory circuit designed for a broad range of applications. It supports a wide operating temperature range of -40 to +105 degrees Celsius, and incorporates a variety of features to ensure highly reliable power system monitoring. This device offers full reset control and protection features to safeguard customer-facing system applications and reduces the need for external components.

In a PMIC - Supervisors application, the S-1003NA50I-M5T1U serves as a watchdog timer and primary reset system. It is designed to monitor and detect excessive currents and voltages, defective system operation and other conditions that may affect system performance. When these conditions are detected, the S-1003NA50I-M5T1U will initiate system reset using a built-in reset controller. The device also features an internal resistor network to modify reset timing and control the length of reset.

The S-1003NA50I-M5T1U supports an adjustable reset threshold and output voltage for advanced system control and protection. Its internal comparator monitors the state of the supply voltage, and will compare it to the internal threshold voltage. If the supply voltage exceeds the threshold, the internal circuit will be triggered and the output of the S-1003NA50I-M5T1U will be driven low for a reset pulse. The output voltage can be adjusted to accommodate various system voltages and power sources. The adjustable delay function also allows for easy fine-tuning of the reset timing.

In addition to reset control, the S-1003NA50I-M5T1U provides system protection features, such as brown-out protection, which reduce the risk of system failure due to voltage transients. The device’s polarity protection feature prevents erroneous operation due to inverted voltage inputs. The S-1003NA50I-M5T1U also features adjustable overload-protection (OLP) limits, which can be set up to allow protection against excessive current, power-on reset and external reset. Furthermore, the device supports hot swap for extended system availability in the event of power or supply interruptions.

The S-1003NA50I-M5T1U is specifically designed for use in a variety of industrial, automotive and consumer applications. Its low power consumption and wide operating temperature range make it an ideal solution for embedded systems and portable applications. Additionally, the device’s wide reset voltage range, adjustable reset timing and polarity protection features make it suitable for a variety of specialized applications.

In summary, the S-1003NA50I-M5T1U is a versatile reset and protection device for a broad range of PMIC - Supervisors applications. It offers reliable power system monitoring, reset control, protection and other features to ensure maximum system performance and reliability in various operating environments.
