Description and Introduction

Power Management IC (PMIC) for Li-Ion Powered Systems 40-VQFN -40 to 85 The TPS65022RHARG4 is a power management IC (PMIC) manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TPS65022RHARG4  
- **Package:** VQFN-32 (5x5mm)  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Output Voltage:** Configurable (buck converters and LDOs)  
- **Number of Buck Converters:** 3 (step-down DC-DC converters)  
- **Number of LDOs:** 2 (low-dropout linear regulators)  
- **Switching Frequency:** Up to 2.25MHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **I2C Interface:** Yes (programmable output voltages and control)  

### **Descriptions:**  
The TPS65022RHARG4 is a highly integrated power management IC designed for portable applications, such as processors and system-on-chip (SoC) power solutions. It combines three step-down converters and two LDOs in a compact package, providing efficient power conversion and management. The device supports I2C programmability for flexible voltage settings and power sequencing.  

### **Features:**  
- **Integrated Power Solution:** Combines three buck converters and two LDOs in a single chip.  
- **High Efficiency:** Synchronous buck converters with up to 95% efficiency.  
- **I2C Programmable:** Allows dynamic voltage scaling and power sequencing control.  
- **Low Quiescent Current:** Optimized for battery-powered applications.  
- **Power Sequencing Support:** Configurable startup and shutdown sequencing.  
- **Protection Features:** Overcurrent, overvoltage, and thermal shutdown protection.  
- **Compact Footprint:** 32-pin VQFN package (5x5mm) for space-constrained designs.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Power Management IC (PMIC) for Li-Ion Powered Systems 40-VQFN -40 to 85

Alternative Part Number

  • TPS65023RHAR --: Same TPS6502x power-management family in the same QFN package with comparable rails and sequencing, making it a close functional drop-in for many designs.
  • TPS650250RHAR --: Related TI multi-rail PMIC in the same RHA package and pin family, offering similar regulator integration for portable systems.
  • MAX8660ETL+ --: Alternative multi-output PMIC from a different vendor with comparable buck/linear rails, suitable when a cross-vendor second source is needed.
