5V / 12V (15V) Dedicated Microprocessor Voltage Monitors The MAX8215CSD is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (formerly Maxim Integrated Products, now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:
### **Specifications:**
- **Manufacturer:** Maxim Integrated (now part of Analog Devices)
- **Part Number:** MAX8215CSD
- **Package:** SOIC-14
- **Type:** Microprocessor (μP) Supervisory Circuit
- **Operating Voltage Range:** 1.2V to 5.5V
- **Reset Threshold Accuracy:** ±1.5% (typical)
- **Reset Timeout Period:** Adjustable or fixed (depending on variant)
- **Operating Temperature Range:** -40°C to +85°C (Commercial/Industrial)
- **Manual Reset Input:** Yes (active-low)
- **Watchdog Timer:** Yes (in some variants)
- **Power-On Reset (POR):** Yes
### **Descriptions:**
The MAX8215CSD is a low-power microprocessor supervisory circuit designed to monitor system power supply voltages and provide a reset signal to the μP in case of power failure or brownout conditions. It ensures reliable system operation by holding the μP in reset until the supply voltage stabilizes.
### **Features:**
- **Precision Voltage Monitoring:** Monitors VCC and generates a reset signal when voltage falls below a preset threshold.
- **Manual Reset Capability:** Includes an active-low manual reset input for user-initiated system resets.
- **Low Quiescent Current:** Typically consumes low power, making it suitable for battery-powered applications.
- **Adjustable or Fixed Reset Threshold:** Some variants allow adjustment of the reset threshold via external resistors.
- **Watchdog Timer (if applicable):** Monitors μP activity and triggers a reset if the μP fails to toggle the watchdog input within a set time.
- **Power-On Reset (POR) Circuitry:** Ensures a valid reset signal upon power-up.
- **Wide Operating Voltage Range:** Supports operation from 1.2V to 5.5V, making it versatile for different logic levels.
