Detailed Pin Configuration

The MAX6385XS43D1-T has a total of six pins:

GND: Ground connection
VCC: Supply voltage input
TH: Threshold voltage selection pin
RESET#: Active-low reset output
MR#: Manual reset input
NC: No connection

Functional Features

Monitors the voltage level at the TH pin and compares it with the selected threshold voltage.
When the voltage at the TH pin drops below the threshold, the RESET# pin is asserted low.
The RESET# pin remains low until the voltage at the TH pin rises above the threshold or a manual reset is triggered.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows for flexibility in various applications. - Low quiescent current minimizes power consumption. - Adjustable threshold voltage options provide customization.

Disadvantages: - Limited number of threshold voltage options available. - SOT23-6 package may not be suitable for all applications.

Working Principles

The MAX6385XS43D1-T is a voltage monitor IC that operates by comparing the voltage at the TH pin with the selected threshold voltage. When the voltage at the TH pin drops below the threshold, the RESET# pin is activated low, indicating a voltage fault or power loss. The RESET# pin remains low until the voltage at the TH pin rises above the threshold or a manual reset is triggered through the MR# pin.
