# Industrial Specification: Valve Drive Circuit

## 1. Technical Definition
Electronic circuit that controls and drives valve actuators in industrial systems

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **24-48 VDC at 2-10 A, 0-100% PWM duty cycle, -40°C to +85°C ambient temperature**. Failure boundary: **Voltage exceeding 60 VDC causes MOSFET gate oxide breakdown, current exceeding 15 A induces thermal runaway at 175°C junction temperature**, Mechanism: **Electromigration in copper traces at current densities &gt; 10^6 A/cm², dielectric breakdown at electric fields &gt; 10 MV/m in gate oxides**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.
