## Application Scope
✅ **Automotive Electronics (Primary Market)**
1. BCM Body Control Module: automotive rear lamps, brake lamps, turn‑signal lamps, LED combination rear lamps, halogen lamp loads
2. Solenoid and relay coil driving (inductive loads)
3. Small DC motor driving: door locks, rear‑view mirrors, window actuators
4. Automotive ground‑referenced loads requiring current monitoring and fault diagnosis
✅ **Industrial (Use caution for non‑automotive applications)**
12V‑24V industrial equipment requiring high‑side switch with current sensing and fault reporting; load switches and solenoid drivers for industrial control boards.
⚠️ Notes
1. Designed for **ground‑referenced loads**. Energy dissipation shall be considered for inductive loads; refer to the datasheet for ground‑loop protection circuits.
2. AEC‑Q100 qualified; prioritized for automotive customers. Cost‑inefficient for general consumer products.
3. The MultiSense function converts current and temperature into analog voltages for ADC input, eliminating external sense resistors.
