Product details

Overview

L6206PD013TR 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, and integrated fast freewheeling diodes.

For engineers reviewing the L6206PD013TR datasheet, L6206PD013TR pinout, L6206PD013TR application, or L6206PD013TR equivalent, this device supports high-frequency PWM motor control up to 100 kHz, provides diagnostic open-drain outputs (OCDA/OCDB), enables paralleled operation for current scaling, and integrates cross-conduction protection with 1 µs deadtime.

Technical Context

The L6206PD013TR integrates two independent full-bridge power stages using BCD technology, each with matched N-channel high-side and N-channel low-side DMOS transistors. It employs an internal charge pump (VCP output, 600 kHz typ.) to generate bootstrap voltage (VBOOT) for high-side gate drive, eliminating external high-voltage bias supplies.

Its non-dissipative overcurrent detection monitors high-side current via on-die sensing elements-no external sense resistor required-and delivers fault signals through open-drain OCDA/OCDB pins. Thermal shutdown activates at 165 °C (typ.) with 15 °C hysteresis, and undervoltage lockout ensures operation only above 6.6 V supply threshold.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	8–52 V: Enables direct integration into 12 V, 24 V, and 48 V industrial motor systems without external regulation.
Peak Output Current	5.6 A per bridge: Supports driving high-torque bipolar 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 DC, reducing heatsink requirements.
Switching Frequency	Up to 100 kHz: Allows fine-resolution microstepping in stepper applications and low-audible-noise PWM control.
Overcurrent Threshold	Programmable from 0.57 A to 5.6 A via PROGCLA/PROGCLB resistors: Enables precise current limiting without hardware redesign.
Thermal Shutdown	165 °C junction temperature (15 °C hysteresis): Prevents irreversible die damage during sustained overload or poor PCB thermal layout.
Diagnostic Outputs	OCDA & OCDB open-drain pins: Provide direct fault signaling for MCU GPIO interrupt handling or hardware enable disable loops.

Pinout & Package

Available in PowerSO36 package (exposed thermal slug, pins 1/18/19/36 internally connected to GND), optimized for high-power motor drive thermal performance. Pinout validated per STMicroelectronics DocID07617 Rev 4 (Figure 2, Table 4).

Pin/Terminal	Circuit Role	Design Meaning
IN1A / IN2A / IN1B / IN2B	Bridge logic inputs	TTL/CMOS-compatible control signals defining H-bridge state (L-L, H-L, L-H, H-H) per bridge; support 1.8 V logic thresholds.
ENA / ENB	Bridge enable inputs	Active-high enables; tied to OCDA/OCDB for automatic fault shutdown-low-level disables all MOSFETs in respective bridge.
OUT1A / OUT2A / OUT1B / OUT2B	Power outputs	Direct connection points to motor windings; each pair forms one full H-bridge capable of bidirectional current flow.
SENSEA / SENSEB	Current sense reference	Must connect directly to power ground (or low-inductance shunt); serves as source node for high-side current sensing circuitry.
OCDA / OCDB	Fault diagnostic outputs	Open-drain outputs pulled low during overcurrent or thermal fault; require external pull-up for MCU interrupt or enable feedback.
PROGCLA / PROGCLB	Overcurrent programming	Resistor-to-GND sets current limit threshold; grounding selects max 5.6 A; 5 kΩ–40 kΩ yields ±10% accuracy range.
VBOOT / VCP	Bootstrap supply interface	VBOOT powers high-side gate drivers; VCP (600 kHz square wave) drives external charge pump (C_BOOT, C_P, D₁, D₂) for VBOOT generation.

Key Features

Feature	Design Value
Integrated fast freewheeling diodes	Eliminates need for 8 external Schottky diodes, reducing BOM count and PCB area while ensuring controlled current recirculation.
Cross-conduction protection	1 µs typ. deadtime between high-side and low-side switching prevents shoot-through current and associated power loss/failure.
Non-dissipative overcurrent detection	On-die high-side current sensing removes external sense resistor and its power dissipation (up to several watts), simplifying thermal design.
Paralleled operation support	Enables doubling output current capability by connecting OUT1A↔OUT1B and OUT2A↔OUT2B-requires synchronized EN/IN signals.
Thermal shutdown with hysteresis	165 °C trip + 15 °C hysteresis avoids oscillatory shutdown/restart during transient thermal overload conditions.

Industrial Actuator Interface

Use Scenario: Simultaneous control of four small DC motors in HVAC damper actuators or medical infusion pump mechanisms.

IC Role / Device Role / Timing Role: Full-bridge pairs configured as two independent dual-motor drivers, sharing VSA/VSB supply rails and diagnostics.

Use Value: Single-chip solution replaces two discrete half-bridge ICs, cutting board space by >30% and interconnect complexity.

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 1.2 A continuous current rating; no programmable overcurrent; uses external sense resistors.	Suitable for low-power robotics but lacks thermal robustness and diagnostic capability for industrial loads.	Select when cost sensitivity outweighs current capability and diagnostics-requires added BOM for sensing and protection.
VNH7040AS	Single-channel high-side driver (not dual full-bridge); requires external H-bridge configuration and external freewheeling diodes.	Used in automotive body control modules-not drop-in compatible for stepper or dual DC motor topologies.	Choose only for single-load high-side switching with ISO 16750 compliance; not functionally equivalent for L6206PD013TR use cases.

Compared with TB6612FNG and VNH7040AS, the L6206PD013TR uniquely combines dual full-bridge topology, programmable overcurrent, integrated freewheeling diodes, and diagnostic outputs in a single PowerSO36 package-making it optimal for space-constrained, thermally demanding industrial motor control where reliability and feature integration are critical.

FAQ

What is the maximum operating frequency for PWM control with L6206PD013TR?

The L6206PD013TR supports switching frequencies up to 100 kHz, verified in electrical characteristics (Table 5) and confirmed in application section 6. This enables high-resolution microstepping in stepper systems and minimizes audible noise in DC motor applications-provided PCB layout maintains low-inductance power paths and proper charge pump component selection (C_BOOT = 220 nF, C_P = 10 nF).

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

The L6206PD013TR uses on-die high-side DMOS current mirroring-each upper transistor includes a scaled replica that delivers a precise fraction (~1/200) of output current to the OCD comparator. This eliminates external sense resistors and their associated power loss (up to several watts), while maintaining ±10% accuracy across temperature when programmed with 5–40 kΩ resistors on PROGCLA/PROGCLB pins.

Can L6206PD013TR drive a unipolar stepper motor?

No-the L6206PD013TR is designed exclusively for bipolar stepper motors and dual/quad DC motors. Its dual full-bridge architecture provides four quadrant control (±V, ±I) required for bipolar winding excitation. Unipolar steppers require center-tapped windings and single-polarity drive per phase, which this IC does not support; using it would require rewiring and forfeit half the torque capability.

What thermal management practices are recommended for PowerSO36 mounting?

For reliable operation at rated current, mount the L6206PD013TR's PowerSO36 package on a multilayer FR4 PCB with ≥6 cm² copper pour on the bottom layer connected to pins 1/18/19/36 (GND slug), plus 16 thermal vias to inner ground planes. Per Table 3, this achieves R_th-j-amb = 15 °C/W-enabling 2.8 A DC operation at ≤70 °C ambient without external heatsink. Avoid solder mask over thermal copper.
