🛡️ 3. Safety & Protection Features

⚠️

Smart Thermal Protection

Linear derating above 85°C MOSFET temp, shut-off protection above 100°C.

⚠️

Hardware-Level Overcurrent/Short-Circuit

High-frequency high-current closed-loop response (<10ms), microsecond gate turn-off.

⚠️

Overvoltage/Undervoltage Lockout

Prevents power battery over-discharge/overcharge, supports regenerative braking overvoltage protection.

⚠️

Failsafe Protection

Safe braking and deceleration within 100ms after control wire or CAN bus signal loss.
