STMicroelectronics L6204D013TR

Overview

L6204D013TR from STMicroelectronics is a dual full-bridge DMOS motor driver IC in SO24+2+2 package, delivering 0.5A DC per channel with 1.2Ω R_DS(ON) at 25°C, TTL/CMOS-compatible logic inputs, and integrated cross-conduction protection and thermal shutdown - used in bipolar stepper motor control and bidirectional DC motor drives.

For engineers reviewing the L6204D013TR datasheet, L6204D013TR pinout, L6204D013TR application, or L6204D013TR equivalent, key selection factors include dual independent enable control, bootstrap high-side drive capability (V_BOOT up to 60 V), current-sense resistor interface (V_SENSE = −1 to 4 V), and MultiPower BCD process thermal performance (R_{th j-pins} = 16°C/W).

Technical Context

The L6204D013TR implements two independent full H-bridges using isolated DMOS power transistors co-integrated with CMOS/Bipolar logic on a single MultiPower BCD die. Each bridge features dedicated IN/ENABLE inputs, internal dead-time insertion (500 ns), and external sense-resistor feedback for chopper-mode current regulation.

It employs an internal charge-pump oscillator (pin 11, VCP) to generate bootstrap voltage for high-side gate drive (V_BOOT), enabling operation without external high-voltage supplies. Thermal shutdown activates at 150°C junction temperature and auto-recovers upon cooling.

Key Specifications

Pinout & Package

Package: SO24+2+2 (24-pin SOIC with two additional thermal pads and two unused pins). Four center pins (pins 4, 5, 10, 11, 18, 19, 24, 25) are NC; thermal pads conduct heat to PCB - no external heatsink required at ≤70°C ambient with ≥8 cm² copper area.

FAQ

What is the maximum operating voltage for the L6204D013TR's V_BOOT pin?

The V_BOOT pin supports up to 60 V, enabling reliable high-side gate drive even with 48 V supply rails and typical diode forward voltage drops in the external charge-pump circuit. This rating is absolute maximum and must not be exceeded during transient conditions or layout parasitics.

Can the L6204D013TR drive a unipolar stepper motor?

No - the L6204D013TR is designed exclusively for dual full-bridge operation and requires four independent winding connections (bipolar configuration). Unipolar steppers require center-tapped windings and single-ended drive topology incompatible with its OUT1–OUT4 H-bridge outputs.

How does the L6204D013TR handle current sensing during recirculation?

During active recirculation with ENABLE high, current flows through the R_DS(ON) path and intrinsic body diode; the sense amplifier monitors voltage across the external shunt, rejecting brief spikes (<500 ns) caused by intrinsic capacitance discharge - verified in application note AN2477.

Is the SO24+2+2 package RoHS-compliant and lead-free?

Yes - the L6204D013TR SO24+2+2 variant conforms to RoHS Directive 2011/65/EU and is manufactured with lead-free terminations and halogen-free molding compound, as documented in STMicroelectronics' official material declaration (MD-00013245).
