Description and Introduction

Surface Mount Sensors The **SS541AT** is a **bipolar latching Hall-effect sensor** manufactured by **Honeywell**. Below are its specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Operating Voltage:** 3.8 V to 24 V  
- **Output Type:** Open-collector  
- **Output Current (sink):** 20 mA (max)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Magnetic Sensitivity:**  
  - **BOP (Operate Point):** 35 G (typical)  
  - **BRP (Release Point):** -35 G (typical)  
- **Switching Frequency:** Up to 20 kHz  
- **Package Type:** TO-92 (3-pin)  

### **Descriptions:**  
- The **SS541AT** is a **latching Hall-effect sensor**, meaning it retains its output state (on/off) even after the magnetic field is removed until an opposite polarity field is applied.  
- It is designed for **digital applications** requiring reliable magnetic sensing, such as position detection, speed sensing, and proximity switching.  
- The sensor operates over a **wide voltage range** (3.8 V to 24 V), making it suitable for automotive, industrial, and consumer electronics applications.  

### **Features:**  
- **Bipolar latching operation** (responds to alternating north and south magnetic poles).  
- **Reverse polarity protection** on the power supply.  
- **High sensitivity** to low magnetic fields.  
- **Robust design** for harsh environments (high-temperature operation up to +150°C).  
- **Low power consumption** in standby mode.

Application Scenarios & Design Considerations

Surface Mount Sensors

Alternative Part Number

  • A1220LLHLT-T --: Two-wire chopper-stabilized Hall-effect sensor switch with similar SOT-23 package and automotive-grade temperature range, suitable as a functional replacement for the SS541AT.
  • MLX92231LSE-AAA-000-RE --: Hall-effect latch/switch in a small SOT package with comparable magnetic sensitivity and supply voltage range, offering a different series as a drop-in style alternative.
  • TLE4905L --: Unipolar Hall-effect switch in SOT-23-like package with similar operating voltage and output behavior, widely used as a cross-reference for Honeywell SS5xx sensors.
