Description and Introduction

-5V,-12V,-15V, and Adjustable Inverting Current-Mode PWM Regulators The MAX736CPD 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  
- **Type:** Microprocessor Supervisory Circuit  
- **Package:** PDIP (Plastic Dual In-Line Package)  
- **Pin Count:** 16  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Reset Timeout Period:** Adjustable (typically 200ms)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Watchdog Timer:** Yes (programmable)  
- **Manual Reset Input:** Yes  
- **Power-Fail Comparator:** Yes  
- **Battery Backup Switching:** Yes  

### **Descriptions:**  
The MAX736CPD is designed to monitor power supply voltages in microprocessor-based systems. It ensures proper system operation by generating a reset signal if the supply voltage drops below a preset threshold. It includes a watchdog timer, manual reset input, and power-fail comparator for enhanced system reliability.  

### **Features:**  
- **Voltage Monitoring:** Monitors +5V supply with precision.  
- **Programmable Watchdog Timer:** Prevents system lockup.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Power-Fail Comparator:** Early warning for power loss.  
- **Battery Backup Support:** Facilitates switchover to backup power.  
- **Low Power Consumption:** Suitable for battery-operated systems.  
- **High Noise Immunity:** Robust performance in noisy environments.  

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

Application Scenarios & Design Considerations

-5V,-12V,-15V, and Adjustable Inverting Current-Mode PWM Regulators

Alternative Part Number

  • LT1054CP --: Pin-compatible switched-capacitor voltage converter in DIP-14 with similar inverting/regulating function; widely used as a MAX736 substitute.
  • ICL7660CPA --: Classic DIP-8 charge-pump voltage inverter covering similar negative-supply conversion needs, though pinout differs and requires rewiring.
  • TC7660CPA --: Low-cost DIP-8 charge-pump inverter with comparable voltage conversion capability; suitable functional replacement with layout changes.
