Description and Introduction

3-Channel Supervisor With Over-Current Detect For Switch-Mode Power Supplies The TPS3513D is a power supply supervisor IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 13.2V  
- **Adjustable Reset Delay Time:** 1ms to 10s (set via external capacitor)  
- **Reset Threshold Accuracy:** ±1.5% (over temperature)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (D)  

### **Descriptions:**  
The TPS3513D monitors the voltage of power supplies in electronic systems and provides a reset signal to the processor or microcontroller when the voltage falls below a preset threshold. It ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Adjustable Reset Threshold:** Allows customization for different voltage levels.  
- **Manual Reset Input:** Supports external push-button reset functionality.  
- **Low Quiescent Current:** Typically 35µA, reducing power consumption.  
- **Power-On Reset (POR) Generator:** Ensures a valid reset signal upon power-up.  
- **Open-Drain Reset Output:** Compatible with multiple logic levels.  
- **Wide Operating Voltage Range:** Suitable for 5V and 3.3V systems.  

This IC is commonly used in embedded systems, industrial controls, and computing applications where reliable power monitoring is critical.

Application Scenarios & Design Considerations

3-Channel Supervisor With Over-Current Detect For Switch-Mode Power Supplies

Alternative Part Number

  • SG6516DZ --: Supervisor/voltage-monitor IC in an SOIC package with similar supply-voltage monitoring functions, usable as a functional substitute in many power-supply supervisory circuits.
  • MC3423P1 --: Overvoltage protection and supervisory controller with comparable monitoring behavior; check pinout and threshold settings before substitution.
  • LM393DR --: Dual comparator that can implement equivalent voltage-monitoring and fault-detection logic when the supervisory function is built discretely; widely available and cost-effective.
