Product Overview: MAX6386XS23D3+ from Maxim Integrated

The MAX6386XS23D3+ is a robust, high-precision microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated. This compact device is engineered to monitor power supplies in digital systems, providing a reliable safeguard against low-voltage conditions that could lead to system malfunctions. It is particularly suitable for use in a variety of applications, including portable devices, computers, controllers, and intelligent instruments.

One of the key features of the MAX6386XS23D3+ is its ability to assert a reset signal whenever the VCC supply voltage falls below its preset threshold of 2.3V. This reset signal ensures that the µP and other critical components within the system are held in a reset state until stable power is restored, thus preventing any erratic behavior or data corruption. The reset output remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, which provides sufficient time for the system to stabilize.

The device comes in a small, 4-pin SC70 package, which is ideal for space-constrained applications. Additionally, its low supply current of 1.2µA (typical) makes it an excellent choice for battery-powered devices where power efficiency is crucial. The MAX6386XS23D3+ operates over a wide temperature range of -40°C to +125°C, ensuring reliability and performance even in extreme environmental conditions.

Furthermore, the MAX6386XS23D3+ features a debounced manual reset input. This allows the user to trigger a reset manually, providing an additional layer of control. The manual reset can be used to initiate a system restart, to enter test modes, or to implement a user-commanded reset function.

Overall, Maxim Integrated's MAX6386XS23D3+ is a versatile and reliable solution for power supply monitoring. Its precision voltage monitoring, low power consumption, and small form factor make it an indispensable component for systems requiring high reliability and operational integrity.
