# Industrial Specification: Power Driver Module

## 1. Technical Definition
Electronic control unit that converts control signals into power signals to drive actuators in an Action Executor system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **24-48 VDC input, 0-20 mA control signal, -40°C to +85°C ambient temperature**. Failure boundary: **Input voltage exceeding 60 VDC causes MOSFET gate oxide breakdown at 6 MV/cm dielectric strength, control signal exceeding 25 mA saturates op-amp circuits, junction temperature exceeding 150°C triggers thermal shutdown**, Mechanism: **Electromigration in copper traces at current densities &gt; 10^6 A/cm², dielectric breakdown in MOSFET gate oxide at electric fields &gt; 6 MV/cm, thermal expansion mismatch between silicon die (CTE 2.6 ppm/°C) and FR-4 substrate (CTE 14 ppm/°C) causing solder joint fatigue**.

### 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.
