Pin Configuration

The MAX161ACWI+T IC has a total of 16 pins. The pin configuration is as follows:

| Pin Number | Pin Name | Function | |------------|----------|----------| | 1 | VCC | Power Supply Voltage | | 2 | GND | Ground | | 3 | RESET | Reset Output | | 4 | MR | Manual Reset Input | | 5 | TH | Threshold Voltage Input | | 6 | CT | Capacitor Connection for Reset Timeout | | 7-14 | NC | No Connect | | 15 | RESET | Reset Output | | 16 | VCC | Power Supply Voltage |

Functional Features

  • Monitors the supply voltage and asserts a reset signal when it falls below a specified threshold.
  • Provides a manual reset input for immediate system reset.
  • Offers adjustable or fixed threshold voltage options to suit different applications.
  • Allows programming of the reset timeout period for customized system behavior.
  • Low quiescent current consumption ensures minimal power usage.

Advantages and Disadvantages

Advantages

  • Precise voltage monitoring helps prevent data corruption and system malfunction.
  • Adjustable threshold voltage allows flexibility in setting the desired voltage level for reset.
  • Programmable reset timeout period enables customization based on specific application requirements.
  • Low-power operation minimizes energy consumption, making it suitable for battery-powered devices.

Disadvantages

  • Limited number of pins may restrict the integration of additional features.
  • Requires an external capacitor for configuring the reset timeout period.

Working Principles

The MAX161ACWI+T operates by continuously monitoring the supply voltage using the TH (Threshold Voltage) pin. When the voltage falls below the set threshold, the RESET output is asserted, indicating a low-voltage condition. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered through the MR pin.

The IC also provides the option to program the reset timeout period using an external capacitor connected to the CT (Capacitor Connection for Reset Timeout) pin. This feature allows customization of the time delay between the voltage rising above the threshold and the deassertion of the reset signal.
