Product details
Overview
L6207PD013TR 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 RDS(ON) at 25 °C, supports up to 100 kHz switching, and implements non-dissipative overcurrent protection and slow-decay synchronous rectification.
For engineers reviewing the L6207PD013TR datasheet, L6207PD013TR pinout, L6207PD013TR application, or L6207PD013TR equivalent, this page provides verified technical context, package-specific pin mapping, real-world motor drive use cases, and validated alternative options for industrial motion control designs.
Technical Context
The L6207PD013TR integrates two independent full-bridge power stages using BCD technology, each with N-channel high-side and low-side DMOS transistors and intrinsic fast freewheeling diodes. Each bridge includes a constant tOFF PWM current controller that regulates load current via external RC networks on RCA/RCB pins and internal sense comparators referenced to VREFA/VREFB.
It employs deadtime-based cross-conduction protection (1 µs typical), bootstrap gate drive (VBOOT, VCP oscillator at 0.6 MHz), and non-dissipative high-side current sensing for overcurrent detection. 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 range | 8–52 V - Supports wide-input 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 dual 24 V DC motors up to ~70 W per channel. |
| RDS(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 switching frequency | Up to 100 kHz - Allows fine current resolution and reduced audible noise in stepper microstepping applications. |
| tOFF programmability | 13–6000 µs via ROFF/COFF - Enables precise current decay tuning for torque consistency across speed and load variations. |
| Thermal shutdown threshold | 165 °C - Provides fail-safe protection during stall, overload, or inadequate heatsinking in enclosed enclosures. |
| Non-dissipative OCD | Detects >5.6 A fault without external sense resistor - Eliminates 1–2 W of wasted power and PCB area in high-current paths. |
Pinout & Package
Available in PowerSO36 package (exposed slug thermally connected to GND pins 1, 18, 19, 36); optimized for high-power motor drive with low junction-to-case thermal resistance (1 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1A / IN2A / IN1B / IN2B | Bridge logic inputs | TTL/CMOS-compatible; define H-bridge direction (forward/reverse/brake) per bridge with truth table compliance. |
| ENA / ENB | Bridge enable with fault feedback | Active-high enables; pulled low by internal open-drain MOS during overcurrent/thermal fault - enables programmable recovery delay via R-C network. |
| SENSEA / SENSEB | Current sense reference | Connect to ground via external shunt; blanked for 1 µs to reject diode reverse-recovery spikes during PWM turn-on. |
| RCA / RCB | PWM off-time timing node | RC network sets monostable tOFF; 20 kΩ–100 kΩ + 0.47 nF–100 nF yields 6.6 µs–6 ms off time for flexible decay control. |
| VREFA / VREFB | Current reference input | Analog voltage (0–5 V) sets peak current limit; ±5 mV offset ensures <1% current regulation error at nominal settings. |
| VSA / VSB | Bridge power supply inputs | Must be tied together externally; each supplies one full bridge - decoupling required near pins to suppress switching noise. |
| OUT1A / OUT2A / OUT1B / OUT2B | Power outputs | Drive motor windings directly; support bidirectional current flow and synchronous rectification in slow-decay mode. |
| VBOOT / VCP | Bootstrap gate drive | VCP (0.6 MHz square wave) charges external bootstrap capacitor to drive high-side N-MOS gates above VS rail. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent PWM current controllers | Each bridge has separate RCA/VREFA and RCB/VREFB inputs - enables asymmetric current profiles for hybrid stepper or differential DC motor control. |
| Slow-decay synchronous rectification | After tOFF, upper MOS conducts as low-loss diode replacement - reduces heat rise by ~30% vs. freewheeling diode decay at 2.8 A. |
| Non-dissipative overcurrent protection | Integrated high-side current mirroring eliminates external 5–10 mΩ shunt and associated 1–2 W loss - improves efficiency and simplifies layout. |
| Cross-conduction prevention | 1 µs programmable deadtime between high/low-side switching - prevents shoot-through even under fast edge rates and temperature drift. |
| Thermal shutdown with hysteresis | 165 °C trip, ~15 °C hysteresis - avoids oscillation during transient overload while ensuring safe restart after cooling. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual H-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB6600HG | Higher peak current (4.5 A RMS vs. 2.8 A), but no integrated PWM current control - requires external current loop. | Targeted at high-current stepper only; lacks dual independent regulation and non-dissipative OCD. | Choose when driving >3 A stepper loads with external current feedback; avoid if space or BOM count is constrained. |
| DRV8876PWPR | Single H-bridge (not dual), 3.6 A peak, integrated current regulation, but no bootstrap drive - limited to low-side switch or external high-side FET. | Requires two ICs for dual-motor function; lacks slow-decay sync rectification and non-dissipative OCD. | Prefer for compact single-axis designs where dual integration isn't needed; not drop-in for L6207's dual-bridge footprint. |
Compared with TB6600HG and DRV8876PWPR, the L6207PD013TR uniquely combines dual independent PWM current control, non-dissipative overcurrent protection, and slow-decay synchronous rectification in a single PowerSO36 package - making it optimal for space-constrained, thermally sensitive dual-motor systems requiring minimal external components.

FAQ
What is the maximum continuous output current per bridge for L6207PD013TR?
The L6207PD013TR supports 2.8 A RMS continuous output current per bridge at Tj ≤ 125 °C with adequate PCB copper area (6 cm² top-side dissipation, 15 °C/W Rth-j-amb). Peak current reaches 5.6 A for <1 ms pulses. Derating is required above 100 °C ambient or with insufficient copper; thermal shutdown activates at 165 °C junction temperature.
How does the non-dissipative overcurrent protection work without an external sense resistor?
The L6207PD013TR embeds high-side current mirroring circuitry within each DMOS power transistor. A precise fraction (~1:2000) of the output current is routed internally to the EN pin comparator, eliminating the need for external shunts. When sensed current exceeds 5.6 A, EN is actively pulled low via an internal 4 mA open-drain MOSFET, signaling fault without dissipating watts in a resistor.
Can L6207PD013TR drive unipolar stepper motors?
No - the L6207PD013TR is designed exclusively for bipolar stepper motors and dual DC motors. Its dual full-bridge topology requires four-wire (or six-wire with center taps unused) bipolar windings. Unipolar steppers require five- or six-lead configurations with common-center taps and single-polarity drive, which this IC cannot support due to lack of half-bridge-only mode or center-tap switching logic.
What is the minimum recommended VREF voltage for stable current regulation?
The minimum recommended VREF voltage is 0.1 V, per datasheet Section 2 (Recommended Operating Conditions). Below this, comparator offset errors dominate, causing inconsistent current limiting. For 2.8 A RMS output with 0.34 Ω RDS(ON), VREF ≥ 0.5 V is advised to ensure ≥10× signal-to-noise margin against ±5 mV offset and PCB noise coupling into the VREF net.
