# Industrial Specification: Recovery Controller

## 1. Technical Definition
A control unit within an Error Handler system that manages the recovery process from operational faults or failures.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **3.3-5.0 VDC, -40 to 85°C, 0-95% RH non-condensing**. Failure boundary: **Voltage &lt;2.7 VDC or &gt;5.5 VDC, temperature &gt;125°C junction, &gt;10^6 ESD discharge at 8 kV HBM**, Mechanism: **Electromigration at current density &gt;10^6 A/cm², dielectric breakdown at electric field &gt;10 MV/m, latch-up from parasitic PNPN structure activation**.

### 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.
