Description and Introduction

HIGH-VOLTAGE EL LAMP DRIVER The **IMP803IMA** is a **supervisory circuit** manufactured by **IMP**. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 1.8V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.6V, 2.32V, 2.93V, 3.08V, 4.38V, etc.)  
- **Reset Timeout Period:** 140ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOT-23-5  

### **Descriptions:**
- The IMP803IMA is a **low-power voltage supervisor** designed to monitor system voltages in microprocessors, DSPs, and other digital systems.  
- It provides a **reset signal** to the host system when the supply voltage falls below a preset threshold, ensuring proper initialization during power-up, power-down, or brownout conditions.  
- It features a **manual reset input** for external system control.  

### **Features:**
- **Low Quiescent Current:** Typically 3µA  
- **Precision Voltage Monitoring:** Ensures reliable system reset  
- **Manual Reset Capability:** Allows external triggering of reset  
- **Wide Operating Voltage Range:** Supports 1.8V to 5.5V systems  
- **Small Form Factor:** Available in a compact SOT-23-5 package  

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

Application Scenarios & Design Considerations

HIGH-VOLTAGE EL LAMP DRIVER

Alternative Part Number

  • LTC6992CS6-1#PBF --: Silicon oscillator in a small SOT-23 package that can replace the IMP803IMA oscillator function with similar frequency programming flexibility.
  • NE555DR --: Widely available general-purpose timer IC in SOIC-8 that can implement the oscillator/timing function of the original part in many designs.
  • TLC555IDR --: Low-power CMOS timer in SOIC-8 offering lower supply current than the bipolar 555, suitable as a functional substitute for the IMP803IMA timing oscillator.
  • LTC1154CS8 --: High-side gate driver in SO-8 with similar drive capability and pin-compatible function, widely available and well documented.
  • MIC5014BM --: High-side MOSFET driver in an 8-pin package offering comparable input thresholds and drive current, suitable as a functional substitute.
  • IRS2001PBF --: High-side driver IC with similar voltage and current ratings, commonly used as a cross-reference for IMP803-class drivers.
