Description and Introduction

Linear Charger for Single-Cell Li Battery The MAX1898EUB42 is a linear battery charger IC manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX1898EUB42  
- **Package:** 10-pin µMAX (UB)  
- **Input Voltage Range:** 4.5V to 12V  
- **Charge Voltage:** 4.2V (fixed)  
- **Charge Current:** Programmable up to 1.5A  
- **Charging Accuracy:** ±0.75%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The MAX1898EUB42 is a standalone linear Li-ion battery charger designed for single-cell Li-ion or Li-polymer batteries.  
- It integrates a current-sense amplifier, MOSFET pass transistor, and thermal regulation circuitry.  
- The device operates without requiring an external microcontroller, making it suitable for simple charging applications.  
- It features an automatic charge termination based on current threshold and includes safety timers.  

### **Features:**
- **Programmable Charge Current:** Adjustable via an external resistor.  
- **Thermal Regulation:** Reduces charge current if die temperature exceeds a safe limit.  
- **Charge Status Outputs:** Open-drain outputs indicate charging (CHG) and power-good (POK) status.  
- **Automatic Recharge:** Initiates a new charge cycle if battery voltage falls below a threshold.  
- **Low Battery Leakage:** <2µA when input power is removed.  
- **Safety Timer:** Prevents overcharging with a programmable timeout period.
