Description and Introduction

SPI-Compatible RTC in a TDFN The MAX6902ETA+T is a microprocessor (µP) supervisory circuit manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (for 3.3V operation)  
- **Reset Timeout Period:** Adjustable (typ. 200ms with external capacitor)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 8-pin TDFN (3mm x 3mm)  
- **Low Quiescent Current:** 35µA (typ)  
- **Manual Reset Input:** Yes (active-low)  
- **Watchdog Timer:** Yes (1.6s timeout default)  
- **Battery Backup Switchover:** Yes (for supply voltages below threshold)  

### **Descriptions:**  
The MAX6902ETA+T monitors µP and digital systems for power supply issues, ensuring reliable operation. It provides a reset signal during power-up, power-down, and brownout conditions. The watchdog timer resets the µP if it fails to toggle within a set period.  

### **Features:**  
- **Power-Fail Comparator:** Detects impending power failure  
- **Battery Backup Support:** Automatically switches to backup supply  
- **Adjustable Reset Timeout:** Via external capacitor  
- **Watchdog Timer:** Prevents µP lockup  
- **Manual Reset Input:** Allows user-initiated reset  
- **Space-Saving TDFN Package:** Suitable for compact designs  

This device is ideal for applications requiring reliable power monitoring, such as embedded systems, industrial controls, and battery-powered devices.
