Description and Introduction

High-Accuracy, Low-Dropout Linear Regulators The MAX688CUA-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-pin μMAX  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.575V, 2.32V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 9μA (typ)  
- **Manual Reset Input:** Yes (active-low)  
- **Watchdog Timer:** Yes (1.6s timeout)  
- **Power-Fail Comparator:** No  

### **Descriptions:**
The MAX688CUA-T is a low-power microprocessor supervisory circuit designed to monitor system voltage and provide a reset signal to the μP during power-up, power-down, or brownout conditions. It includes a watchdog timer and manual reset input for additional system reliability.  

### **Features:**
- **Low Power Consumption:** 9μA typical supply current  
- **Adjustable or Fixed Reset Thresholds:** Multiple preset voltage options  
- **Manual Reset Input:** Allows external reset triggering  
- **Watchdog Timer:** Monitors µP activity; resets if software fails  
- **Small Package:** 8-pin μMAX for space-constrained applications  
- **Wide Operating Voltage Range:** 1.2V to 5.5V  
- **Guaranteed Reset Output Valid Down to VCC = 1V**  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Description and Introduction

High-Accuracy, Low-Dropout Linear Regulators The MAX688CUA-T is a microprocessor voltage monitor manufactured by Maxim Integrated. Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
Maxim Integrated  

### **Part Number:**  
MAX688CUA-T  

### **Description:**  
The MAX688CUA-T is a voltage monitor designed to supervise microprocessor power supplies. It ensures proper system operation by monitoring multiple voltage rails and providing a reset signal if any voltage falls below a preset threshold.  

### **Key Features:**  
- **Number of Monitored Voltages:** 3  
- **Adjustable or Fixed Threshold:** Fixed  
- **Reset Timeout Period:** Adjustable via external capacitor  
- **Reset Output Type:** Active-low, push-pull  
- **Operating Voltage Range:** 1.6V to 5.5V  
- **Supply Current:** 20µA (typical)  
- **Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX  

### **Applications:**  
- Microprocessor and microcontroller supervision  
- Embedded systems  
- Industrial controls  
- Power supply monitoring  

### **Additional Notes:**  
- Provides manual reset input (MR) for external reset control.  
- Guaranteed reset output valid down to VCC = 1V.  

For exact threshold voltages and timing specifications, refer to the official datasheet from Maxim Integrated.
