High-side driver with 2.5 A continuous output and fault monitoring
The STMicroelectronics L6370D013TR is a single-channel high-side N-channel power driver in a PowerSO-20 package. It delivers up to 2.5 A continuous from a load supply of 9.5 V to 35 V.
2.5 A output — sizing the load budget
The 2.5 A continuous rating defines the maximum steady-state load current. The fixed current-limiting protection clamps the output during overload.
Fault protection set — what each block does
Four independent protection circuits are built in: current limiting (fixed threshold), open-load detection, overtemperature shutdown, and undervoltage lockout (UVLO). The Status Flag output goes active when any of these events occur, giving the host controller a single digital feedback line. Open-load detection is particularly useful for verifying the load is connected before switching on — a common requirement in safety-related output stages. UVLO prevents the driver from operating below the minimum supply voltage, avoiding undefined conduction states during power-up or brownout.
