  • Monitors the voltage level of a power supply and generates a reset signal when the voltage falls below a specified threshold.
  • Provides a reliable way to ensure proper operation of electronic systems by resetting them when the power supply voltage is insufficient.
• Package: TDFN-6 (Thin Dual Flat No-Lead) package
• Essence: Voltage monitoring and reset functionality in a compact package
• Packaging/Quantity: Tape and Reel, 2500 units per reel

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Threshold Voltage Options: 2.5V, 3.0V, 3.3V, 5.0V
• Reset Timeout Period: Adjustable from 1ms to 640ms
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX6363HUT44+T IC has the following pin configuration:

```

---

| | --| VCC | --| GND | --| MR | --| RESET | --| RESET_OUT | |___________| ```

• VCC: Power supply input
• GND: Ground reference
• MR: Manual reset input (active-low)
• RESET: Output that goes low when the monitored voltage falls below the threshold
• RESET_OUT: Open-drain output that asserts low during the reset timeout period

Functional Features

• Voltage monitoring: Monitors the power supply voltage continuously
• Threshold selection: Multiple threshold voltage options available for different applications
• Adjustable reset timeout: Allows customization of the reset timeout period
• Manual reset capability: Provides a manual reset option through the MR pin
• Open-drain output: RESET_OUT pin allows easy interfacing with other devices

Advantages and Disadvantages

Advantages: - Compact package size - Wide supply voltage range - Adjustable reset timeout period - Manual reset capability - Multiple threshold voltage options

Disadvantages: - Limited to voltage monitoring and reset functionality only - Requires an external power supply

Working Principles

The MAX6363HUT44+T operates by continuously monitoring the power supply voltage. When the voltage falls below the selected threshold, the RESET pin goes low, indicating a voltage fault. The RESET_OUT pin also asserts low during the reset timeout period, providing a signal to other devices that a reset is in progress. The manual reset (MR) pin can be used to force a reset regardless of the monitored voltage level.
