Product details

Overview

L6207D 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 implements non-dissipative overcurrent protection on high-side MOSFETs.

For engineers reviewing the L6207D datasheet, L6207D pinout, L6207D application, or L6207D equivalent, this page provides verified technical context, package-specific pin mapping, real-world motor drive use cases, and validated alternative options for dual H-bridge current-controlled systems.

Technical Context

The L6207D integrates two independent BCD-technology full bridges with isolated DMOS power transistors, CMOS logic, and bipolar circuitry on a single die. Each bridge includes a constant t_OFF PWM current controller using external RC networks (RCA/RCB) to set decay timing, with 1 µs internal deadtime to prevent cross-conduction.

It employs slow-decay synchronous rectification and non-dissipative overcurrent detection via embedded high-side current sensing - eliminating external sense resistors. Thermal shutdown triggers at 165 °C, and undervoltage lockout activates below 5.6 V supply.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	8–52 V - supports wide industrial and automotive battery-fed motor systems without external regulation.
Peak output current	5.6 A per bridge - enables driving high-torque stepper phases or 24 V DC motors up to ~100 W per channel.
R_DS(ON) (HS, 25 °C)	0.34 Ω typ. - limits conduction loss to ≤4.8 W per bridge at 2.8 A DC, easing thermal design on PCB.
PWM frequency	Up to 100 kHz - allows fine current resolution and low audible noise in stepper microstepping.
t_OFF range	13–6000 µs - programmable via RCA/RCB RC networks, supporting torque control across diverse motor inductances.
Thermal shutdown	165 °C - protects against sustained overload or poor heatsinking; auto-recovery after cooldown.
Logic interface	TTL/CMOS-compatible IN/EN pins with 1.8 V turn-on threshold - ensures robust interfacing with MCU GPIOs.

Pinout & Package

Available in PowerSO36 (exposed slug, GND-connected) and SO24 (20 + 2 + 2 lead count) packages. Both support high-power dissipation via PCB copper planes; PowerSO36 offers 1 °C/W junction-to-case thermal resistance.

Pin/Terminal	Circuit Role	Design Meaning
IN1A / IN2A / IN1B / IN2B	Bridge logic inputs	Control direction per bridge (H/L truth table); TTL/CMOS compatible with 1.8 V threshold.
ENA / ENB	Bridge enable inputs	Active-high enables; internally tied to OCD/thermal fault transistor drain - requires 2.2–180 kΩ pull-up if open-drain driven.
SENSEA / SENSEB	Current sense return	Connect to ground via external shunt resistor (for legacy mode); unused in non-dissipative OCD mode.
RCA / RCB	PWM off-time timing	RC network sets t_OFF; 20 kΩ–100 kΩ + 0.47–100 nF yields 13 µs–6 ms off time.
VREFA / VREFB	Current reference input	0–5 V analog input sets peak current limit; 0.5 V → ~2.8 A with typical R_SENSE = 0.1 Ω (if used).
VSA / VSB	Bridge power supplies	Independent 8–52 V inputs per bridge; must be tied together externally for shared supply operation.
OUT1A / OUT2A / OUT1B / OUT2B	Full-bridge outputs	Drive motor windings directly; include integrated fast freewheeling diodes (1.15 V forward drop @2.8 A).
VBOOT	Bootstrap supply	Drives high-side N-MOS gates; requires external 220 nF boot capacitor and charge pump (VCP oscillator @600 kHz).

Key Features

Feature	Design Value
Dual independent PWM current controllers	Each bridge uses separate RCA/RCB and VREFA/VREFB for asymmetric current tuning - essential for bipolar stepper phase balancing.
Non-dissipative overcurrent protection	Eliminates external sense resistors and associated I²R losses - reduces BOM cost and PCB area while maintaining 5.6 A trip accuracy.
Slow-decay synchronous rectification	Reduces power loss during current recirculation vs. fast decay; improves efficiency in high-inductance stepper applications.
Cross-conduction protection	1 µs guaranteed deadtime prevents shoot-through - enables safe operation even with asymmetric gate drive delays.
Integrated charge pump (VCP)	600 kHz internal oscillator drives external bootstrap circuit - removes need for external clock source or complex gate driver ICs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual H-bridge current-controlled motor drive applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TB6600HG	Higher 4.5 A RMS rating but no integrated charge pump; requires external bootstrap circuit and separate current sense amps.	Targeted at high-voltage (>60 V) stepper systems; lacks non-dissipative OCD and thermal shutdown flag output.	Choose when operating >52 V or needing higher peak current; accept added board complexity and missing safety features.
DRV8825	Microstepping-focused with built-in indexer; lower 2.2 A RMS rating and 45 V max supply; no dual-bridge independence (shared VREF).	Optimized for compact 3D printer mainboards; lacks slow-decay mode and independent bridge enable/control.	Prefer for space-constrained consumer-grade stepper systems where microstepping resolution > current control flexibility.

Compared with TB6600HG and DRV8825, the L6207D uniquely combines dual independent PWM current control, non-dissipative overcurrent protection, and slow-decay operation in a single IC - making it optimal for industrial dual-motor systems demanding reliability, thermal resilience, and minimal BOM overhead.

FAQ

What is the minimum required external component set for basic L6207D operation?

A functional L6207D circuit requires: two 220 nF boot capacitors (one per bridge), one 10 nF CP capacitor, one 100 Ω RP resistor, two 1N4148 diodes for the charge pump, and RC networks (RCA/RCB + COFF) to set t_OFF. No external sense resistors are needed due to non-dissipative OCD.

Can L6207D drive unipolar stepper motors?

No - the L6207D is designed exclusively for dual full-bridge topologies and cannot configure its outputs for unipolar (5-wire) stepper operation. Its IN/EN logic and output structure require four dedicated winding terminals per motor, matching only bipolar (4-wire) or dual-winding configurations.

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

Each high-side DMOS includes an integrated current mirror that delivers ~1/1000 of the load current to the EN pin. When this mirrored current exceeds 4 mA (corresponding to ~5.6 A load), the EN pin is pulled low to disable the bridge - eliminating power loss and thermal drift issues inherent in shunt-based sensing.

Is PowerSO36 package pin-compatible with SO24 for drop-in replacement?

No - PowerSO36 (36-pin) and SO24 (24-pin) have fundamentally different pin counts and layouts. While both support identical electrical functionality, PCB redesign is required to migrate between packages; thermal performance and current capability differ significantly due to exposed slug vs. standard SO footprint.
