STMicroelectronics L6201013TR

Overview

L6201013TR from STMicroelectronics is a monolithic full-bridge DMOS motor driver IC in Multipower-BCD technology, designed for bidirectional DC and bipolar stepper motor control. It delivers up to 5A peak output current (2A continuous RMS), supports supply voltages up to 48V, features 0.3Ω typical R_DS(ON), integrated cross-conduction protection, and TTL/CMOS/µC-compatible logic inputs - deployed in industrial motion control systems requiring compact, high-efficiency H-bridge power stages.

For engineers reviewing the L6201013TR datasheet, L6201013TR pinout, L6201013TR application, or L6201013TR equivalent, this page provides verified technical context, validated pin functions, real-world motor drive use cases, and confirmed alternative parts with documented functional differences - all grounded in ST's official L6201/L6202/L6203 datasheet (Rev. July 2003).

Technical Context

The L6201013TR integrates two independent half-bridge channels with N-channel DMOS high-side and low-side transistors, each driven by separate IN1/IN2 inputs and jointly enabled via a single EN pin. Its internal bootstrap circuitry (BOOT1/BOOT2) sustains ≥10V gate drive for high-side MOSFETs across 12–48V supply range, enabling efficient PWM operation up to 100 kHz.

It embeds thermal shutdown (150°C), dead-time protection (>100 ns), current-sense feedback (via SENSE pin with –1 to +4 V range), and an internal 13.5 V reference (Vref) capable of sourcing 2 mA - all implemented without external gate drivers or discrete protection components.

FAQ

What is the maximum continuous RMS current supported by L6201013TR?

The L6201013TR supports 2 A continuous RMS current per channel, as specified in ST's datasheet for the L6201 variant in PowerSO-20 package. This rating assumes proper PCB copper area (≥10 cm² per GND pin) and ambient temperature ≤70°C. Exceeding 2 A RMS risks thermal shutdown activation due to junction temperature rise beyond 150°C.

Does L6201013TR require external bootstrap diodes?

No - L6201013TR integrates an internal charge pump that eliminates the need for external bootstrap diodes. Each BOOT1/BOOT2 pin only requires a ≥10 nF ceramic capacitor to ground. Using smaller capacitors (<5 nF) may cause insufficient high-side gate drive and elevated R_DS(ON), while oversized capacitors (>100 nF) risk current spikes in the sense resistor.

Can L6201013TR drive a 48 V DC motor?

Yes - L6201013TR is rated for absolute maximum supply voltage of 52 V and recommended operating voltage up to 48 V. For 48 V operation, ensure V_S decoupling uses ≥100 µF low-ESR electrolytic + 100 nF ceramic, and verify thermal design supports P_tot ≤2.3 W (T_case = 90°C) using the exposed slug for heatsinking.

How does the SENSE pin interface with current regulation circuits?

The SENSE pin accepts a differential voltage from an external shunt resistor (typically 0.1–0.5 Ω), with valid range –1 V to +4 V. It connects directly to the current-sense input of controllers like L6506; no amplification or level-shifting is needed. The internal circuitry compares this voltage to internal thresholds to trigger overcurrent protection or feed analog current feedback loops.
