Description and Introduction

Low Power Narrowband FM IF (revA) The MC3371 is a battery cell controller IC manufactured by NXP Semiconductors. It is designed for use in automotive and industrial battery management systems (BMS). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 3.0V to 5.5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Communication Interface:** SPI (Serial Peripheral Interface)  
- **Cell Voltage Measurement Range:** 0V to 5V  
- **Cell Voltage Measurement Accuracy:** ±10mV (typical)  
- **Current Measurement:** Supports external shunt resistor  
- **Integrated ADC Resolution:** 16-bit  
- **Number of Supported Cells:** Up to 14 cells in series  
- **Package Type:** 64-pin LQFP  

### **Descriptions:**
- The MC3371 is a highly integrated battery cell controller that provides accurate voltage, current, and temperature monitoring for lithium-ion battery packs.  
- It is part of NXP's battery management IC family, optimized for hybrid and electric vehicle (HEV/EV) applications.  
- The device supports daisy-chaining for multi-module battery systems, enabling scalable BMS architectures.  

### **Features:**
- **Cell Voltage Monitoring:** Measures individual cell voltages with high precision.  
- **Temperature Monitoring:** Supports multiple external thermistor inputs.  
- **Balancing Control:** Integrated passive cell balancing with programmable current limits.  
- **Fault Detection:** Includes overvoltage, undervoltage, and overtemperature protection.  
- **Low Power Modes:** Supports sleep and standby modes for reduced power consumption.  
- **Isolation Communication:** Compatible with isolated SPI for high-voltage safety.  
- **Diagnostics:** Built-in self-test and fault reporting capabilities.  

The MC3371 is widely used in automotive BMS applications due to its reliability, accuracy, and compliance with industry safety standards.
