CMOS Micropower Step-UP Switching Regulator The MAX630CSA 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 (μP) Supervisory Circuit
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)
- **Operating Voltage Range:** 1.2V to 5.5V
- **Reset Threshold Options:** Factory-set or adjustable
- **Reset Timeout Period:** Adjustable via external capacitor
- **Operating Temperature Range:** 0°C to +70°C (Commercial grade)
- **Watchdog Timer:** Yes, with programmable timeout
- **Manual Reset Input:** Available (active-low)
- **Power-On Reset (POR):** Yes
- **Low-Power Consumption:** Typically 5μA (varies with configuration)
### **Descriptions:**
The MAX630CSA is designed to monitor power supply voltages in microprocessor-based systems, ensuring reliable operation by generating a reset signal if the voltage drops below a specified threshold. It includes a watchdog timer to detect software lockups and a manual reset input for user-initiated system resets.
### **Features:**
- **Voltage Monitoring:** Ensures proper μP operation by generating a reset when VCC falls below the threshold.
- **Adjustable Reset Threshold:** Can be set externally or uses factory-preset values.
- **Watchdog Timer:** Monitors system activity; triggers reset if not toggled within a set time.
- **Manual Reset Capability:** Allows external reset initiation via a pushbutton.
- **Low Quiescent Current:** Minimizes power consumption in battery-operated systems.
- **Wide Supply Range:** Supports operation from 1.2V to 5.5V.
- **Power-On Reset (POR):** Ensures a valid reset signal upon power-up.
