# Industrial Specification: Voltage Comparator

## 1. Technical Definition
An electronic circuit that compares two input voltages and outputs a digital signal indicating which is larger.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-36 V differential input voltage, -40°C to +125°C ambient temperature**. Failure boundary: **Input voltage differential exceeding 40 V causes breakdown, junction temperature exceeding 150°C initiates thermal runaway**, Mechanism: **Dielectric breakdown of input protection diodes at 40 V, semiconductor junction thermal runaway at 150°C due to positive temperature coefficient**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Input voltage differential exceeding 40 V | 8 | Input protection diode avalanche breakdown causing permanent short circuit | Series current-limiting resistor of 1 kΩ with 5 W power rating before input pins |
| Ambient temperature exceeding 125°C with 10 mA output current | 8 | Thermal runaway leading to output stage latch-up and permanent failure | Thermal pad with 2.5°C/W thermal resistance to chassis ground |
