Product details

Overview

L6206D013TR from STMicroelectronics is a DMOS dual full-bridge motor driver IC designed for bipolar stepper and dual/quad DC motor control, featuring 5.6 A peak output current per bridge, 0.34 Ω typical high-side R_DS(ON) at 25 °C, programmable overcurrent detection (5.6 A ±30% threshold), and integrated fast freewheeling diodes.

For engineers reviewing the L6206D013TR datasheet, L6206D013TR pinout, L6206D013TR application, or L6206D013TR equivalent, this device supports high-frequency PWM motor control up to 100 kHz, includes diagnostic open-drain outputs (OCDA/OCDB), cross-conduction protection, thermal shutdown at 165 °C, and bootstrap charge-pump operation for N-channel high-side drive.

Technical Context

The L6206D013TR integrates two independent full-bridge power stages using BCD technology, each with matched N-channel high-side and P-channel low-side DMOS transistors. It employs a 600 kHz internal charge-pump oscillator (VCP) to generate VBOOT for high-side gate drive, enabling efficient operation without external high-voltage bias supplies.

Its non-dissipative overcurrent detection monitors high-side current via on-die sensing elements-eliminating external shunt resistors-and provides fault signaling through open-drain OCDA/OCDB pins. Logic inputs (IN1A/IN2A/ENA, IN1B/IN2B/ENB) are TTL/CMOS-compatible with 1.8 V turn-on and 1.3 V turn-off thresholds and 0.5 µs typical deadtime between complementary switches.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage range	8–52 V - supports wide industrial DC bus voltages including 12 V, 24 V, and 48 V systems.
Peak output current	5.6 A per bridge - enables driving high-torque stepper motors or dual brushed DC motors under pulse loads.
R_DS(ON) (high-side, 25 °C)	0.34 Ω typ. - limits conduction loss to ~5.4 W per bridge at 4 A RMS, reducing heatsink requirements.
Switching frequency	Up to 100 kHz - allows fine-grained microstepping control and low audible noise in stepper applications.
Overcurrent threshold	Programmable from 0.57 A to 5.6 A via PROGCLA/PROGCLB resistor - enables precise current limiting without external sense resistors.
Thermal shutdown	165 °C junction temperature with 15 °C hysteresis - prevents irreversible die damage during overload or poor PCB thermal design.
Diagnostic outputs	OCDA & OCDB open-drain pins - provide direct fault indication for system-level safety logic or microcontroller interrupt handling.

Pinout & Package

Available in PowerSO36 (exposed slug, thermally enhanced) and SO24 (20 + 2 + 2 pin count) packages. The L6206D013TR uses the SO24 package variant, with GND pins (1, 6, 7, 18, 19) serving dual roles as signal reference and PCB heat dissipation paths.

Pin/Terminal	Circuit Role	Design Meaning
IN1A / IN2A / IN1B / IN2B	Bridge logic inputs	Control H-bridge direction and mode (forward/reverse/brake/coast) per bridge via standard TTL/CMOS levels.
ENA / ENB	Bridge enable inputs	Active-low enables; tied to OCDA/OCDB for automatic fault shutdown with RC-programmed recovery delay.
OUT1A / OUT2A / OUT1B / OUT2B	Power outputs	Drive motor windings directly; each pair forms one full-bridge leg capable of bidirectional current flow.
SENSEA / SENSEB	Current sense return	Low-impedance connection point for high-side current sensing; must be routed with minimal trace length to ground plane.
OCDA / OCDB	Fault diagnostic outputs	Open-drain outputs pulled low during overcurrent or thermal fault; require external pull-up for microcontroller interfacing.
VSA / VSB	Bridge power supplies	Independent supply inputs for each bridge; must be connected together externally to common DC bus.
VBOOT	Bootstrap voltage	Supplies gate drive for high-side N-MOSFETs; generated internally via VCP-driven external charge-pump network (CBOOT, CP, D1, D2).
PROGCLA / PROGCLB	Overcurrent programming	Resistor-to-ground sets bridge-specific current limit; grounding selects maximum 5.6 A threshold.

Key Features

Feature	Design Value
Dual independent full bridges	Enables simultaneous control of two bipolar stepper phases or four independent DC motors in H-bridge configuration.
Integrated fast freewheeling diodes	Eliminates need for 8 external Schottky diodes, reducing BOM count and board area while ensuring reliable flyback energy recirculation.
Non-dissipative overcurrent detection	Replaces 2–4 mΩ shunt resistors and associated op-amp circuitry, saving >1 W of board-level power dissipation per bridge.
Cross-conduction protection	Hardware-enforced 0.5–1 µs deadtime prevents shoot-through current during switching transitions, improving reliability and efficiency.
Paralleled operation support	Allows pairing half-bridges across A/B channels (e.g., OUT1A + OUT1B) to double current capability while maintaining independent fault detection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual full-bridge motor driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TB6612FNG	Lower 3.2 A peak current, 5 V logic supply only, no bootstrap circuit or programmable OCD.	Suitable for low-voltage (≤15 V), low-power robotics but lacks 48 V compatibility and precision current limiting.	Select when cost sensitivity outweighs performance needs and supply voltage stays below 13.5 V.
VNH7040AS	Single-channel high-side driver with integrated current sense; not a dual full-bridge IC.	Requires external H-bridge topology and separate logic for direction control; no built-in deadtime or diagnostics.	Choose only for high-side switch replacement-not as a functional substitute for L6206D013TR's integrated dual-bridge architecture.

Compared with TB6612FNG and VNH7040AS, the L6206D013TR uniquely delivers dual full-bridge operation at up to 52 V with programmable overcurrent protection and diagnostic feedback-making it the only option among the three that supports robust, self-protected bipolar stepper control in industrial 24–48 V systems without external components.

FAQ

What is the recommended charge-pump component layout for stable VBOOT generation?

Use a 220 nF ceramic CBOOT between VBOOT and OUT1A/OUT2A, a 10 nF CP between VCP and GND, and 1N4148 diodes for D1/D2. Place CBOOT within 5 mm of the IC with short, wide traces to minimize loop inductance. Mount RP (100 Ω) close to VCP to damp oscillation. Avoid routing VBOOT near noisy signals.

How does the non-dissipative overcurrent detection work without a shunt resistor?

The L6206D013TR embeds precision current-mirror circuitry inside each high-side DMOS transistor. A small, fixed fraction (~1:2000) of the main output current is mirrored to an internal comparator, comparing it against a reference set by PROGCLA/PROGCLB. This eliminates external shunts while maintaining ±10% accuracy across temperature.

Can L6206D013TR drive unipolar stepper motors?

No-it is designed exclusively for bipolar stepper motors requiring full-bridge current reversal per phase. Unipolar steppers use center-tapped windings and require different drive topologies (e.g., ULN2003 or dedicated unipolar drivers). Attempting unipolar operation risks incorrect current paths and potential device damage.

What thermal derating applies when using the SO24 package without a heatsink?

In free-air conditions (R_th-j-amb = 77 °C/W), the SO24 package limits continuous output current to ~1.4 A per bridge at 25 °C ambient. With 6 cm² copper pour on bottom layer (R_th-j-amb = 51 °C/W), RMS current rises to ~2.1 A. For 2.8 A DC operation, a heatsink or PowerSO36 package is required.
