MAX6383LT28D2+T

A supervisor integrated circuit (IC) is an important tool for protecting the microcontroller from latch-up, excessive voltage/current, and reset isolation. The MAX6383LT28D2+T is an example of such a supervisor IC. It is designed to be used in automotive, industrial, and telecom applications, with extended operating temperature range of -40 degrees C to 125 degrees C. It has a wide range of features, including a watchdog timer, adjustable reset threshold, reset output assertion, and reset delay time-out.

The MAX6383LT28D2+T is a three-terminal supervisory IC with an adjustable reset threshold. It offers high accuracy with a ±2.5% reset threshold accuracy and a 0.2% timer accuracy. It has a watchdog timer with up to 16 ms time-out range and a programmable reset delay time-out which can be adjusted from 0 to 600 ms. It also has a voltage-controlled reset output which is asserted under power-on reset, watchdog time-out, or VDD overvoltage condition. The MAX6383LT28D2+T is also supplied with a delayed reset input feature, suitable for brownout detection.

The working principle of the MAX6383LT28D2+T starts with the circuit’s reset threshold feature. It monitors the supply voltage and if the voltage drops below the programmed reset threshold, the reset output is asserted. The watchdog timer and reset delay time-out features are then activated. The watchdog timer triggers and monitors the system activity and if there is no activity after the timer reaches its time-out and the reset delay time-out expires, the output is asserted low. This can be used to reset the microcontroller or other logic devices.

The MAX6383LT28D2+T is designed to provide an effective reset mechanism, suitable for a wide range of voltage and frequency ranges. Its use of adjustable reset thresholds and a watchdog timer with a programmable time-out make it an ideal choice for automotive, industrial, and telecom applications.

In conclusion, the MAX6383LT28D2+T is a reliable supervisor IC suitable for a variety of applications. Its adjustable reset threshold, adjustable reset delay time-out, and watchdog timer make it an effective tool for protecting the microcontroller from latch-up, excessive voltage/current, and reset isolation. With its extended operating temperature range and high accuracy reset threshold, the MAX6383LT28D2+T is an ideal choice for all kinds of applications.
