Package: The MAX160EWN+ is available in a small SOT23-5 package, which is compact and suitable for space-constrained applications.

Essence: The essence of the MAX160EWN+ lies in its ability to ensure reliable operation of electronic devices by monitoring the power supply voltage and providing a reset signal when necessary.

Packaging/Quantity: The MAX160EWN+ is typically sold in reels containing 3000 units per reel.

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Reset Threshold Voltage Range: 1.2V to VCC-0.2V
• Quiescent Current: 3µA (typical)
• Operating Temperature Range: -40°C to +85°C
• Package Type: SOT23-5

Pin Configuration

The MAX160EWN+ has a total of five pins arranged as follows:

```

---

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

1. RESET: Output pin for the reset signal.
2. GND: Ground reference pin.
3. MR: Manual reset input pin.
4. VCC: Power supply voltage input pin.
5. VCCSENSE: Voltage sense input pin.

Functional Features

1. Voltage Monitoring: The MAX160EWN+ continuously monitors the power supply voltage and compares it with the user-adjustable threshold voltage.
2. Reset Signal Generation: When the power supply voltage falls below the threshold, the MAX160EWN+ generates a reset signal on the RESET pin.
3. Manual Reset: The MR pin allows for manual reset control, enabling the user to initiate a reset regardless of the power supply voltage.
4. Low Quiescent Current: The IC consumes very low quiescent current, making it suitable for battery-powered applications.
5. Wide Operating Temperature Range: The MAX160EWN+ can operate reliably in a wide temperature range, from -40°C to +85°C.

Advantages and Disadvantages

Advantages: - Accurate voltage monitoring and reset functionality - Adjustable threshold voltage for flexibility - Low power consumption - Compact package size - Wide operating temperature range

Disadvantages: - Limited number of pins for additional functionalities - Requires external components for proper operation

Working Principles

The MAX160EWN+ operates by comparing the power supply voltage with the user-adjustable threshold voltage. If the power supply voltage drops below the threshold, the IC generates a reset signal. The manual reset feature allows the user to initiate a reset even if the power supply voltage is within the acceptable range.

Application Field Plans

The MAX160EWN+ finds applications in various electronic devices where reliable power supply monitoring and reset functionality are crucial. Some potential application fields include: - Microcontrollers and microprocessors - Embedded systems - Industrial automation equipment - Consumer electronics - Medical devices

Alternative Models

1. MAX1617: Similar voltage monitor and reset circuit IC with additional features such as watchdog timer and power-fail detection.
2. MAX809: Voltage monitor and reset circuit IC with fixed threshold voltage and push-pull output.

These alternative models offer similar functionality to the MAX160EWN+ and can be considered based on specific application requirements.
