Description and Introduction

Low Cost Power-On Reset and Watchdog Controllers The MAX699CWE is a versatile power-supply sequencer and voltage monitor manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
- **MAX** (Maxim Integrated, now part of Analog Devices)  

### **Part Number:**  
- **MAX699CWE**  

### **Package:**  
- **16-pin Wide SOIC (WSO)**  

### **Description:**  
The MAX699CWE is a power-supply sequencer and voltage monitor designed to control and monitor multiple power supplies in a system. It ensures proper power-up and power-down sequencing to prevent damage to sensitive components.  

### **Key Features:**  
1. **Power-Supply Sequencing:**  
   - Controls up to four power supplies with programmable sequencing.  
   - Adjustable delay between power-up and power-down sequences.  

2. **Voltage Monitoring:**  
   - Monitors up to four power-supply voltages with adjustable thresholds.  
   - Provides undervoltage and overvoltage detection.  

3. **Programmable Delays:**  
   - Configurable delay times for sequencing using external capacitors.  

4. **Reset Output:**  
   - Generates a system reset signal if any monitored voltage falls out of tolerance.  

5. **Wide Operating Voltage Range:**  
   - Operates from **2.7V to 5.5V** supply voltage.  

6. **Low-Power Consumption:**  
   - Low quiescent current for energy-efficient operation.  

7. **Fault Detection:**  
   - Detects power-supply faults and triggers appropriate responses.  

8. **Temperature Range:**  
   - Industrial temperature range: **-40°C to +85°C**.  

### **Applications:**  
- Power-supply sequencing in servers, telecom equipment, and embedded systems.  
- Voltage monitoring in industrial and automotive electronics.  
- System reset generation for microcontrollers and FPGAs.  

This information is based solely on the manufacturer's datasheet and technical specifications.

Application Scenarios & Design Considerations

Low Cost Power-On Reset and Watchdog Controllers

Alternative Part Number

  • ADM699AR --: Microprocessor supervisory circuit with reset and watchdog functions, functionally similar to the MAX699 in a comparable SOIC package.
  • DS1232 --: Well-known microprocessor supervisor IC offering reset and watchdog timing, a common cross-reference for MAX699-type supervisors.
  • TL7705ACP --: Supply voltage supervisor with reset output, widely available and often used as a substitute for MAX699 supervisory functions.
  • ADM699ARZ --: Pin-compatible microprocessor supervisory circuit with reset and watchdog functions, widely available and functionally equivalent to the MAX699.
  • DS1232LPS --: Microprocessor supervisor with reset and watchdog in the same family of functions, suitable drop-in replacement in most supervisory applications.
  • TPS3705-33DGNR --: Supervisory circuit with reset and watchdog timer offering similar functionality, good alternative when the MAX699 is unavailable.
