L6201

Full Half-Bridge (H Bridge) Drivers Overview

The L6201 is a DMOS full bridge driver for motor control applications, realized in Multipower-BCD technology. It combines isolated DMOS power transistors with CMOS and Bipolar circuits on the same chip. The device supports supply voltages up to 48V and features an operating frequency up to 100kHz. Total RMS current is rated at 1A, with a maximum peak current of 5A (2A max for L6201). The typical RDS(ON) is 0.3 Ω at 25°C. Logic inputs are TTL, CMOS, and microcontroller compatible. It includes cross-conduction protection and thermal shutdown.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific package variant required, as the L6201 series includes L6201PS which differs in current rating. Confirm the exact suffix matches the desired output current specification. Check datasheet revisions for any pinout or electrical parameter updates before finalizing design integration.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select based on required RMS current; standard L6201 provides 1A RMS while L6201PS offers 4A RMS. Ensure supply voltage does not exceed 48V. Verify logic level compatibility with the controlling microcontroller. Consider thermal management requirements given the 0.3 Ω RDS(ON) and operating temperature range.
