Pin Configuration

The MAX16088US33A+T has a total of 5 pins:

1. GND (Ground)
2. MR (Manual Reset Input)
3. RESET (Reset Output)
4. VCC (Supply Voltage)
5. WDI (Watchdog Timer Input)

Functional Features

• Voltage monitoring: The MAX16088US33A+T continuously monitors the supply voltage and generates a reset signal if it falls below the preset threshold.
• Manual reset input: The MR pin allows for manual resetting of the system by pulling it low.
• Adjustable reset timeout delay: The reset timeout delay can be adjusted using external capacitors to suit specific system requirements.
• Watchdog timer: The WDI pin is used to feed the watchdog timer, which resets the system if it does not receive a periodic input within the specified timeout period.
• Power-on reset generator: The MAX16088US33A+T includes a power-on reset generator that ensures a fixed delay time before releasing the reset signal during power-up.

Advantages and Disadvantages

Advantages: - Low-power operation - Wide supply voltage range - Adjustable reset timeout delay - Manual reset capability - Battery backup switchover feature

Disadvantages: - Limited number of pins for additional functionalities - Fixed reset threshold voltage

Working Principles

The MAX16088US33A+T works by continuously monitoring the supply voltage. If the voltage falls below the preset threshold (3.3V), the IC generates a reset signal on the RESET pin. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout delay expires. The manual reset input (MR) allows for immediate system reset when pulled low. The watchdog timer ensures system integrity by resetting the system if it does not receive a periodic input within the specified timeout period.
