The SP690SEN-L/TR is an supervisors IC with extraordinary quality and reliability. It is specially designed for microprocessor or logic circuits to protect against inaccurate powering or brown-outs or unintentional restarts. This device senses the voltage level of the input supply and provides a reset signal whenever the voltage level reaches a preset limits. It\'s small in size and easy to use, making it one of the most popular supervisors among manufacturers.

The SP690SEN-L/TR supervisor utilizes a high-speed complementary MOS (CMOS) process, which allows for high accuracy programming and strong output drive capability. The internal supply current is only 600nA and it has a very high accuracy that features a total accuracy of 0.5%. It also features an active low output, an open collector reset signal and a ground flag.

The SP690SEN-L/TR has a wide range of applications. It is ideal for protecting against over voltage, under voltage, and brown-out conditions, as well as being able to signal the microprocessor or logic circuit when the power supply has reached preset thresholds. It can also protect against power outages and other potentially damaging events. It is commonly used in systems containing multiple power supplies, as it is capable of sensing each supply individually and providing reset signals for each one.

The working principle of the SP690SEN-L/TR is relatively straightforward. It utilizes a high-speed CMOS process to sense the voltage level of the input supply. When the input supply voltage reaches a certain level, the supervisor will set the output to the active low level, and the reset signal is then sent. The reset signal is generated immediately so that the system can be shut down or reset if necessary. The device also features a ground flag and can detect ground short circuits.

The SP690SEN-L/TR is an excellent choice for protecting microprocessor or logic circuits against over voltage, under voltage, and brown-out conditions. Its small size and easy use make it a popular choice among manufacturers, and its high-speed CMOS process ensures high accuracy and strong output drive capability. The internal supply current of the device is only 600nA and its total accuracy is 0.5%, making it an ideal choice for protecting delicate electronics.
