Product details

Overview

E-L6207D013TR from STMicroelectronics is a DMOS dual full-bridge motor driver IC with integrated PWM current controllers, designed for bipolar stepper and dual DC motor control. It operates from 8–52 V supply, delivers 5.6 A peak (2.8 A DC) per bridge, features 0.3 Ω typical R_DS(ON) at 25 °C, supports up to 100 kHz switching, and includes non-dissipative overcurrent protection and thermal shutdown.

For engineers reviewing the E-L6207D013TR datasheet, E-L6207D013TR pinout, E-L6207D013TR application, or E-L6207D013TR equivalent, this device is selected for precise current-regulated motor drives requiring independent bridge control, slow-decay synchronous rectification, and robust fault protection in industrial motion systems.

Technical Context

The L6207 integrates two fully independent DMOS full bridges in BCD technology, each with dedicated constant t_OFF PWM current controllers using external RC networks on RCA/RCB pins. Current regulation is achieved by comparing sensed voltage across internal high-side current mirrors against VREF_A/VREF_B, triggering monostable off-time periods.

It implements cross-conduction prevention via 1 µs internal deadtime, slow-decay mode with synchronous rectification during recirculation, and non-dissipative overcurrent detection via integrated high-side current mirrors-eliminating external sense resistors. Thermal shutdown activates at 165 °C, and undervoltage lockout engages below 5.6 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	8–52 V - Enables direct operation from 12 V, 24 V, and 48 V industrial bus rails without external regulators.
Peak output current	5.6 A per bridge - Supports high-torque stepper phases or dual 2.8 A DC motors with short-duration overload capability.
R_DS(ON) (HS, 25 °C)	0.34 Ω typ. - Limits conduction loss to ≤4.8 W per bridge at 2.8 A DC, reducing heatsink requirements.
Switching frequency	Up to 100 kHz - Allows fine current ripple control and acoustic noise suppression in precision motion applications.
t_OFF range	6.6 µs to 6 ms - Programmable via external ROFF (20–100 kΩ) and COFF (0.47–100 nF) for optimal motor inductance matching.
Thermal shutdown	165 °C - Protects silicon integrity under sustained overload or poor PCB thermal design; auto-recovery after cooldown.
Overcurrent threshold	5.6 A typ. - Triggers open-drain EN pin pull-down (4 mA sink) for system-level fault handling without external sensing.

Pinout & Package

Available in PowerSO36 package (exposed slug thermally connected to GND pins 1, 18, 19, 36), optimized for high-power motor drive thermal performance. Pinout validated per STMicroelectronics DocID7513 Rev 3 (2018).

Pin/Terminal	Circuit Role	Design Meaning
IN1A / IN2A / IN1B / IN2B	Bridge logic inputs	TTL/CMOS-compatible control signals defining H-bridge direction (forward/reverse/brake) per bridge.
ENA / ENB	Bridge enable / fault output	Active-high enable; also serves as open-drain fault indicator pulled low during overcurrent or thermal events.
VSA / VSB	Bridge power supplies	Independent 8–52 V inputs for each bridge; must be tied together externally for shared rail operation.
OUT1A / OUT2A / OUT1B / OUT2B	Power outputs	DMOS full-bridge terminals driving motor windings; support bidirectional current flow and freewheeling paths.
SENSEA / SENSEB	Current mirror reference	Connected to ground via optional external resistor only if using dissipative current sensing; otherwise left unconnected.
VREFA / VREFB	PWM reference voltage	Analog inputs setting current limit threshold (0–5 V); 0.5 V yields ~2.8 A RMS with internal gain and sensing ratio.
RCA / RCB	PWM t_OFF timing	RC network nodes controlling off-time duration; sets decay interval for current regulation loop stability.
VBOOT	Bootstrap supply	Drives high-side N-MOS gates above VS; requires external 220 nF bootstrap capacitor and charge pump components.

Key Features

Feature	Design Value
Dual independent PWM current controllers	Each bridge has separate VREF and RC inputs, enabling asymmetric current limits and dynamic tuning for multi-axis systems.
Non-dissipative overcurrent protection	Eliminates external current-sense resistors and associated I²R losses, improving efficiency and simplifying layout.
Slow decay with synchronous rectification	Reduces power dissipation during current recirculation versus fast decay, lowering MOSFET heating in continuous torque modes.
Cross-conduction protection	1 µs guaranteed deadtime prevents shoot-through, ensuring safe switching transitions even under timing skew or noise.
Integrated fast freewheeling diodes	Enables operation without external catch diodes, reducing BOM count and PCB area while maintaining 300 ns reverse recovery.

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
TB6600HG	Higher 4.5 A RMS rating but no integrated PWM controller; requires external current-sense amplifier and comparator.	Lacks built-in t_OFF regulation and non-dissipative OCP; suited for simpler fixed-frequency chopper designs.	Select when cost sensitivity outweighs design simplicity; accept added board space and component count for basic stepper control.
DRV8825	Lower 2.2 A RMS rating, microstepping support, but single-channel; dual units needed for two-motor control.	Optimized for low-voltage (< 45 V), low-current stepper applications with onboard indexer logic.	Choose for compact, low-power stepper systems where microstepping granularity matters more than peak torque or dual-bridge integration.

Compared with TB6600HG and DRV8825, the E-L6207D013TR uniquely combines dual independent bridges, integrated PWM current control, and non-dissipative overcurrent protection in a single PowerSO36 package-reducing system-level complexity for industrial motion control where reliability and thermal efficiency are critical.

FAQ

What is the recommended minimum copper area for thermal management of E-L6207D013TR in PowerSO36 package?

For reliable operation at 2.8 A DC per bridge, ST recommends mounting the PowerSO36 package on a multilayer FR4 PCB with ≥6 cm² of 35 µm-thick copper on the top layer and 16 thermal vias to an internal ground plane. This achieves R_th-j-amb ≈ 15 °C/W, limiting junction temperature rise to <42 °C at ambient 85 °C.

Can E-L6207D013TR operate with only one bridge enabled while the other is unused?

Yes. Bridge B can be fully disabled by holding ENB low, leaving its outputs in high-impedance state. No additional termination or biasing is required. The unused bridge draws only quiescent current (≤10 mA), and its VREFB, RCA, and RCB pins may be left unconnected or tied to GND per layout convenience.

How does the non-dissipative overcurrent protection function without external sense resistors?

The L6207 uses integrated high-side current mirrors that deliver a precise 1/1000 fraction of load current to internal comparators. When mirrored current exceeds the internal 5.6 mA reference (corresponding to 5.6 A load), EN pins are actively pulled low-enabling system-level fault response without power-wasting external shunts or amplifiers.

Is external bootstrap capacitor mandatory for E-L6207D013TR operation?

Yes. A 220 nF ceramic capacitor between VBOOT and VSA is mandatory to sustain gate drive voltage for the high-side N-MOSFETs. Without it, upper transistors cannot turn on, resulting in single-ended (low-side-only) operation and immediate overcurrent faults during intended full-bridge use.
