L6201, L6202, and L6203 are DMOS full bridge drivers with a supply voltage of up to 48V and a maximum peak current of 5A (2A max. for L6201). The total RMS current is up to L6201: 1A; L6202: 1.5A; L6203/L6201PS: 4A. It has an RDS (ON) of 0.3 Ω (typical value at 25 °C), cross conduction protection, TTL compatible drive, operating frequency up to 100 kHz, and thermal shutdown. The internal logic supply ensures high efficiency.
The L6201, L6202 and L6203 are monolithic DMOS full‑bridge drivers realized in Multipower‑BCD technology. They integrate isolated power transistors with CMOS/bipolar control circuits, providing TTL, CMOS and µC compatible inputs for motor‑control applications.
The document details supply voltage limits, peak current capability, pin assignments, electrical and thermal specifications, timing parameters, and mechanical dimensions for the three device variants.
