Product details

Overview

L6207N 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, 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 L6207N datasheet, L6207N pinout, L6207N application, or L6207N equivalent, this device is selected for precision current-regulated motion control where high-side sensing, synchronous rectification, and independent bridge enable/control are required in industrial actuators, CNC stages, and automated optical systems.

Technical Context

The L6207N integrates two fully independent power bridges using BCD technology, each with N-channel high-side and low-side DMOS transistors and intrinsic fast freewheeling diodes. Each bridge employs a constant t_OFF PWM current controller that senses load current via external sense resistors connected to SENSEA/SENSEB pins and regulates using VREFA/VREFB reference voltages.

Cross-conduction prevention is enforced by a 1 µs internal deadtime between complementary MOSFET switching. High-side gate drive is enabled via an internal charge pump (VCP output, 600 kHz typ.) generating VBOOT, eliminating need for external high-voltage bias supplies.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	8–52 V - supports wide-range industrial DC bus operation without external regulation.
Peak output current	5.6 A per bridge - enables driving high-torque stepper phases or 24 V DC motors up to ~80 W per channel.
R_DS(ON) (HS, 25 °C)	0.34 Ω typ. - limits conduction loss to <1.5 W per high-side switch at 2.8 A DC.
PWM frequency max	100 kHz - allows fine current resolution and reduced audible noise in stepper microstepping.
t_OFF range	13–61 µs (with ROFF = 20–100 kΩ, COFF = 1 nF) - sets minimum current decay time for torque stability across motor inductance range.
Thermal shutdown	165 °C - protects against sustained overload or inadequate heatsinking on SO24 or PowerSO36 packages.
Overcurrent threshold	5.6 A typ. - triggers non-dissipative high-side current sensing, eliminating external sense resistor power loss.

Pinout & Package

Available in SO24 (20 + 2 + 2) and PowerSO36 packages. Both feature exposed thermal pads (internally connected to GND pins) for PCB-level heat dissipation. PowerSO36 offers lower junction-to-case thermal resistance (1 °C/W), while SO24 relies on copper area and vias for thermal management.

Pin/Terminal	Circuit Role	Design Meaning
IN1A / IN2A / IN1B / IN2B	Logic input	TTL/CMOS-compatible bridge direction control; defines H-bridge state per truth table (forward/reverse/brake).
ENA / ENB	Bridge enable	Active-high logic input; also serves as open-drain fault output for overcurrent/thermal events - requires external pull-up (100 kΩ recommended).
SENSEA / SENSEB	Current sense return	Low-side sense node; connects to ground via external shunt resistor to enable current feedback for PWM regulation.
VREFA / VREFB	Current reference	Analog voltage input (0–5 V) setting peak current limit; offset tolerance ±5 mV ensures accurate regulation.
RCA / RCB	RC timing network	Sets constant off-time (t_OFF) via external R-C; determines current decay rate and chopper frequency.
VSA / VSB	Bridge power supply	Independent high-voltage inputs (8–52 V) for each bridge; must be tied together externally for single-rail operation.
OUT1A / OUT2A / OUT1B / OUT2B	Power output	Full-bridge terminals driving motor windings; rated for 60 V absolute max differential voltage.
VBOOT	Bootstrap supply	Charge-pump-generated voltage (>VS + 5 V) enabling N-channel high-side gate drive without external boost circuitry.

Key Features

Feature	Design Value
Dual independent PWM current controllers	Enables simultaneous, decoupled current regulation of two motor phases or separate DC motors with distinct reference and timing settings.
Slow decay synchronous rectification	Reduces power loss during current recirculation by turning on high-side MOSFET instead of relying on body diode conduction.
Non-dissipative overcurrent protection	Eliminates external high-power sense resistors by integrating high-side current mirroring - saves board space and thermal load.
Cross-conduction protection	Hardware-enforced 1 µs deadtime prevents shoot-through during bridge commutation, enhancing reliability under transient conditions.
Integrated fast freewheeling diodes	Reduces external component count and improves switching efficiency versus discrete diode solutions - optimized for 2.8 A RMS operation.

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 peak current (4.5 A vs. 5.6 A), no integrated charge pump - requires external bootstrap circuitry for high-side drive.	Targeted at cost-sensitive open-loop stepper systems; lacks non-dissipative OCP and synchronous rectification.	Select when budget constraints outweigh need for thermal efficiency and fault resilience in light-duty applications.
DRV8876N	Lower voltage range (4.5–45 V), integrated current sense amplifier (no external VREF needed), but only single H-bridge per package.	Requires two ICs for dual-motor control; better suited for space-constrained designs needing diagnostic outputs and SPI configuration.	Select when design prioritizes diagnostics, layout simplicity, and supply voltage below 45 V - not for 48 V industrial rails.

Compared with TB6600HG and DRV8876N, the L6207N uniquely combines dual independent bridges, non-dissipative OCP, and self-contained charge pump in one SO24/PowerSO36 package - making it optimal for thermally demanding, high-reliability dual-motor control where board area and external component count are constrained.

FAQ

What is the maximum continuous output current per bridge for L6207N?

The L6207N supports 2.8 A DC (RMS) output current per bridge under proper thermal conditions - verified at T_j ≤ 125 °C with adequate PCB copper area (≥6 cm²) and thermal vias. Peak current reaches 5.6 A for <1 ms pulses, limited by internal overcurrent protection.

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

The L6207N embeds high-side current mirroring circuitry in each DMOS power transistor. A precise fraction of the output current is internally routed to the EN pin comparator, triggering fault response at 5.6 A typical - eliminating external shunt resistors and their associated power loss and board space.

Can L6207N drive a unipolar stepper motor?

No - the L6207N is designed exclusively for bipolar stepper motors and dual DC motors. Its dual full-bridge topology requires four-wire (or six-wire center-tapped) bipolar windings; it cannot configure half-bridge or phase-enable modes required for unipolar operation.

What is the purpose of the RCA and RCB pins, and how are they configured?

RCA and RCB set the constant off-time (t_OFF) for each bridge's PWM current controller via external RC networks. A resistor (20–100 kΩ) and capacitor (0.47–100 nF) connected from RCA/RCB to GND determine t_OFF per Equation: t_OFF ≈ 0.6 × R × C + 1 µs (deadtime). This directly controls current decay rate and chopper frequency.
