Detailed Pin Configuration

The MAX6715AUTSHD3+ features a compact SOT23-6 package with the following pin configuration:

____ NC | | VDD GND| | RESET NC | | MR NC | | TH NC | | GND ----

• VDD: Power supply input
• RESET: Active-low reset output
• MR: Manual reset input
• TH: Threshold adjust input
• GND: Ground

Functional Features

1. Voltage Monitoring: The MAX6715AUTSHD3+ continuously monitors the power supply voltage and compares it to the user-adjustable threshold voltage.
2. Reset Generation: When the monitored voltage falls below the threshold, the circuit generates an active-low reset signal to initiate a system reset.
3. Manual Reset: The MR pin allows for manual reset capability, enabling external control over the reset function.
4. Threshold Adjustment: The TH pin provides the ability to adjust the reset threshold voltage according to specific system requirements.

Advantages and Disadvantages

Advantages: - Wide operating voltage range - Adjustable reset threshold for flexibility - Low quiescent current consumption for power efficiency - Small package size suitable for space-constrained applications

Disadvantages: - Limited number of available alternative models - Lack of built-in protection features (e.g., overvoltage protection)

Working Principles

The MAX6715AUTSHD3+ operates by comparing the power supply voltage with the user-adjustable threshold voltage. If the voltage drops below the threshold, the circuit triggers a reset signal. The manual reset input allows for additional control over the reset function. The low quiescent current consumption ensures minimal power usage during normal operation.
