# Industrial Specification: Control Logic Circuit

## 1. Technical Definition
Electronic circuit that processes input signals and generates control commands for motor operation.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **3.3-5.0 VDC input voltage, -40°C to +85°C ambient temperature, 0-100% relative humidity (non-condensing)**. Failure boundary: **Input voltage exceeding 5.5 VDC causes CMOS latch-up, junction temperature exceeding 150°C initiates thermal runaway, electrostatic discharge above 2000V damages gate oxide**, Mechanism: **Electromigration at current densities above 10^6 A/cm², time-dependent dielectric breakdown at electric fields exceeding 10 MV/cm, hot carrier injection at drain-source voltages above nominal operating voltage**.

### 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.
