The MN1381SL (MN1381) is a type of system supervisor IC. Developed by Tokyo Microelectronics, it is a compact, single-chip application device capable of providing a fail-safe system reset in the event of a power failure or over voltage operation. As a system supervisor, it services a variety of applications ranging from embedded systems to distributed systems with the added capabilities of precision voltage and temperature monitoring.

Due to it’s wide use, the MN1381SL is commonly used in embedded systems such as navigation systems, mobile phones, home gateways, and other types of home appliances. It also has a wide range of applications in distributed systems such as industrial control systems, power distribution systems, power management systems, control and monitoring systems, and other complex electronic network applications which require a reliable and truly fail-safe system reset.

The MN1381SL is designed with an input voltage range of 2.8V to 5.5V, that enables the device to support a wide range of input voltages, including those found in industrial and automotive applications. The device also boasts a single-pin, pull-up input voltage regulator that provides a very low minimum supply voltage, reducing power consumption and increasing battery life. Additionally, the device is equipped with a precision voltage monitor that ensures a stable and accurate voltage level, providing a more consistent system performance and improved reliability.

In order to provide reliable system reset capability, the MN1381SL is equipped with a Reset Switch, which is triggered in the event of a power failure or when a certain voltage level is exceeded. When the Reset Switch is triggered, the device shuts down all peripherals connected to the system and halts system operation. Additionally, the device can be configured with an interrupt pin or with an internal timer to provide additional system reset control.

In addition to providing system reset, the MN1381SL also features a precision temperature monitor which triggers a reset when the device’s temperature exceeds preset limits. This feature prevents system disruption or failure due to thermal overloads and it helps protect the system from high temperature conditions. Moreover, the device also includes a 10-pin SOT-23 package, making it ideal for use in space-constrained applications.

Overall, the MN1381SL supervisor IC provides ultimate system protection in the event of a power supply failure or over voltage operation. Its wide range of features, precision voltage and temperature monitoring capabilities, and small package make it an ideal choice for a variety of applications. Whether in an embedded system or distributed system, the MN1381SL can provide a truly dependable system reset protection.
