Description and Introduction

Dual USB Switch with Fault Blanking The MAX1812EUB is a USB-powered Li+ battery charger from Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Manufacturer:**  
- Maxim Integrated (now Analog Devices)  

### **Part Number:**  
- MAX1812EUB  

### **Package:**  
- 10-pin µMAX® (ultra-small form factor)  

### **Description:**  
- The MAX1812EUB is a single-cell lithium-ion (Li+) battery charger designed for USB-powered applications. It integrates a current-limited adjustable regulator to charge Li+ batteries efficiently from a USB port or an external DC power source.  

### **Key Features:**  
1. **USB-Compliant Charging:**  
   - Operates from a USB port (4.5V to 6.5V input range).  
   - Selectable 100mA or 500mA charge current for USB compliance.  

2. **Adjustable Charge Current:**  
   - External resistor allows setting charge current up to 1A.  

3. **Programmable Charge Voltage:**  
   - Adjustable output voltage (4.1V or 4.2V) for different Li+ battery chemistries.  

4. **Automatic Power Source Selection:**  
   - Switches between USB and external DC power (up to 12V).  

5. **Charge Termination & Safety:**  
   - Charge termination based on minimum current threshold.  
   - Thermal regulation to prevent overheating.  
   - Reverse discharge protection.  

6. **Low-Power Mode:**  
   - Consumes only 15µA when not charging.  

7. **Status Indicators:**  
   - Open-drain outputs for charge status (CHG, POK).  

### **Applications:**  
- USB-powered portable devices.  
- Single-cell Li+ battery chargers.  
- PDAs, smartphones, and handheld electronics.  

### **Datasheet Reference:**  
- For detailed electrical characteristics and application circuits, refer to the official MAX1812EUB datasheet from Analog Devices (formerly Maxim Integrated).  

This information is based solely on the manufacturer's documented specifications.

Application Scenarios & Design Considerations

Dual USB Switch with Fault Blanking

Alternative Part Number

  • TPS2115APW --: Pin-compatible power mux/switch with similar current rating and logic interface, widely available and lower cost.
  • LTC4412ES6 --: Ideal diode/PowerPath controller offering comparable load-switching function in a small package.
  • FSA2269UCX --: Low-resistance analog switch suitable for power/signal routing where the MAX1812 is used as a switch.
  • FSA2269TUMX --: Low-resistance analog switch suitable for power/signal routing in similar applications; good availability.
  • FSA4157P6X --: Low-resistance analog switch usable as a power mux alternative with similar signal switching behavior.
