Description and Introduction

+5V, Low-Power uP Supervisory Circuits with Adjustable Reset/Watchdog The MAX6303CSA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:  

### **Manufacturer:** Maxim Integrated (now Analog Devices)  
### **Part Number:** MAX6303CSA  
### **Package:** 8-pin SOIC  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or factory-set (1.575V, 2.32V, 2.93V, 3.08V, 4.38V)  
- **Reset Timeout Period:** Adjustable (1ms min) or fixed (140ms, 280ms, 560ms, 1.12s)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5μA (typical)  
- **Output Type:** Active-low RESET (open-drain or push-pull)  

### **Descriptions:**  
- Monitors μP and digital system power supplies to ensure proper operation.  
- Generates a reset signal when the supply voltage drops below a preset threshold.  
- Includes manual reset input for external system control.  
- Suitable for battery-powered and low-voltage applications.  

### **Features:**  
- Low quiescent current (5μA) for power-sensitive designs.  
- Adjustable or fixed reset threshold options.  
- Adjustable or fixed reset timeout period.  
- Open-drain or push-pull RESET output configuration.  
- Manual reset input (MR) for external triggering.  
- Small 8-pin SOIC package for space-constrained applications.

Application Scenarios & Design Considerations

+5V, Low-Power uP Supervisory Circuits with Adjustable Reset/Watchdog

Alternative Part Number

  • LTC1686CS8 --: Similar low-power supervisory/reset IC in an SO-8 package with comparable supply monitoring functions; different series name makes it easy to distinguish from the original.
  • ADM809LARTZ --: Pin-compatible style microprocessor reset/supervisory circuit with similar threshold and reset timing behavior, offered in a small SOT-23 package as a functional substitute.
  • TL7705ACD --: Widely available supply voltage supervisor/reset IC with adjustable threshold and reset output, suitable as a cross-series replacement for basic supervisory functions.
  • ADM8691ARZ --: Microprocessor supervisory circuit offering reset, watchdog and power-fail monitoring comparable to the MAX6303, in an SOIC package.
  • TPS3705-33DR --: Supervisory circuit with reset and watchdog timing functions that can replace the MAX6303 in most monitoring applications, in SOIC-8.
  • LTC1235CS8 --: Pin-compatible microprocessor supervisory circuit with similar reset and watchdog functions, widely used as a MAX6303 substitute.
  • ADM706ARZ --: Low-cost supervisory IC offering reset and watchdog timing comparable to the MAX6303, available in SOIC package.
