Description and Introduction

PROXIMITY/TOUCH CONTROL HALOGEN LAMP DIMMER The LS7232NT is a touch dimmer IC manufactured by LSI (LSI Computer Systems).  

### **Specifications:**  
- **Type:** CMOS Touch Dimmer IC  
- **Function:** Controls the brightness of incandescent lamps via touch or proximity sensing.  
- **Output:** Triac driver for AC lamp dimming.  
- **Input:** Touch plate or proximity sensor.  
- **Operating Voltage:** Typically 5V to 12V DC.  
- **Dimming Range:** Adjustable from near-off to full brightness.  
- **Frequency:** Synchronizes with 50Hz/60Hz AC line.  
- **Package:** 8-pin DIP (Dual In-line Package).  

### **Descriptions and Features:**

- **Frequency Range:** 50Hz/60Hz compatible  
- **Touch Sensitivity:** Adjustable via external components  

### **Descriptions:**  
The LS7232NT is a specialized IC designed for touch-controlled dimming applications. It allows for smooth dimming of incandescent lamps or control of AC motor speeds by phase-angle control of a triac. The device responds to touch inputs, eliminating the need for mechanical switches.  

### **Features:**  
- **Touch Control:** Operates via capacitive touch sensing.  
- **Phase Control:** Provides leading-edge dimming for AC loads.  
- **Adjustable Dimming Range:** From full brightness to off.  
- **Noise Immunity:** Built-in noise rejection for stable operation.  
- **Zero-Crossing Detection:** Ensures smooth switching.  
- **External Synchronization:** Compatible with AC line frequency.  
- **Low Standby Power Consumption.**  

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