Description and Introduction

NiCd/NiMH Battery Fast-Charge Controllers The MAX712CSE is a fast-charge controller for nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries, manufactured by Maxim Integrated.  

### **Specifications:**  
- **Package:** 16-pin narrow SOIC (CSE suffix)  
- **Operating Voltage Range:** 5V to 20V  
- **Charge Current:** Adjustable up to 4A  
- **Charge Termination Methods:**  
  - Voltage slope detection (ΔV/Δt)  
  - Maximum voltage cutoff  
  - Maximum temperature cutoff  
  - Maximum time cutoff  
- **Temperature Range:**  
  - **Operating:** 0°C to +70°C  
  - **Storage:** -65°C to +150°C  
- **Key Features:**  
  - Fast charge control for NiCd/NiMH batteries  
  - Programmable charge current and termination thresholds  
  - Built-in safety timers  
  - Supports both voltage and temperature-based charge termination  
  - Low-battery detection  

### **Descriptions and Features:**  
The MAX712CSE is designed to efficiently manage the fast charging of NiCd and NiMH battery packs. It integrates multiple charge termination methods to ensure safe and reliable charging. The device allows for adjustable charge current and supports various safety features, including overvoltage, overtemperature, and timeout protection.  

Key functionalities include automatic charge initiation, charge status indication, and the ability to work with external power supplies. The IC is commonly used in portable electronics, power tools, and backup battery systems requiring fast and controlled charging.

Application Scenarios & Design Considerations

NiCd/NiMH Battery Fast-Charge Controllers

Alternative Part Number

  • BQ2002CSN --: Fast-charge NiCd/NiMH battery controller in SOIC-16 with similar charge-termination features, a common cross for the MAX712 in battery charger designs.
  • LT1510CS --: Constant-current/constant-voltage battery charger IC in SOIC-16 that can replace the MAX712 in many NiCd/NiMH charging applications with comparable current-programming capability.
  • UC3906N --: Sealed lead-acid battery charge controller with voltage and current regulation; usable as a functional substitute where the MAX712 charging scheme is adapted, though package differs (DIP).
  • BQ2002CPN --: Fast-charge NiCd/NiMH battery controller with similar charge-termination features, widely available and often used as a MAX712 substitute.
  • LTC4060EFE --: Standalone linear NiMH/NiCd fast battery charger IC offering comparable charge control functionality in a similar SO package.
  • DS2715Z --: NiMH battery charge controller from the same manufacturer family with similar charge-management capabilities and pin-compatible design intent.
