Product details

Overview

L6208PD013TR from STMicroelectronics is a DMOS dual full-bridge stepper motor driver IC designed for bipolar stepper motor control in industrial motion systems. It delivers 5.6 A peak (2.8 A RMS) output current per bridge, operates from 8–52 V supply, features non-dissipative overcurrent protection, and supports full/half-step excitation with programmable t_OFF PWM current regulation.

For engineers reviewing the L6208PD013TR datasheet, L6208PD013TR pinout, L6208PD013TR application, or L6208PD013TR equivalent, this page provides verified technical context, validated pin functions, confirmed thermal and electrical specs, and real-world use cases for precision open-loop stepper positioning in CNC, robotics, and automated instrumentation.

Technical Context

The L6208 integrates two independent DMOS full bridges with R_DS(ON) = 0.34 Ω (typ, T_j = 25 °C) per high-side switch and built-in fast freewheeling diodes. Its constant t_OFF PWM current controller uses external RC networks on RCA/RCB pins to set decay timing, while internal blanking (1 µs) suppresses diode reverse-recovery spikes at SENSEA/SENSEB.

Logic inputs (CLOCK, CW/CCW, HALF/FULL, CONTROL, EN, RESET) are TTL/CMOS compatible with hysteresis (0.25–0.5 V), and the charge pump (VCP @ 600 kHz typ) generates VBOOT to drive N-channel high-side MOSFETs. Cross-conduction protection enforces 1 µs deadtime between complementary switches in each half-bridge leg.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage range	8–52 V - Enables direct integration into 24 V and 48 V industrial power rails without external DC-DC pre-regulation.
Peak output current	5.6 A - Supports high-torque bipolar stepper motors up to NEMA 23 size in continuous microstepping applications.
R_DS(ON) (HS, 25 °C)	0.34 Ω - Limits conduction loss to ≤4.8 W per bridge at 2.8 A RMS, reducing heatsink requirements in PowerSO36 package.
Max switching frequency	100 kHz - Allows fine-grained current chopping for smooth low-speed operation and reduced audible noise.
t_OFF range	6.6 µs to 6 ms - Set via external ROFF (20–100 kΩ) and COFF (0.47–100 nF); enables optimization for motor inductance and target current ripple.
Thermal shutdown threshold	165 °C - Protects against sustained overload or inadequate PCB copper area; recovery occurs after junction cooldown.
Undervoltage lockout	V_S < 6 V (typ) - Prevents erratic operation during brown-out conditions by disabling all outputs until stable supply resumes.

Pinout & Package

Available in PowerSO36 package (exposed slug thermally connected to pins 1, 18, 19, 36), optimized for high-power dissipation in motor drive applications. The slug must be soldered to a large copper pour for effective thermal management.

Pin/Terminal	Circuit Role	Design Meaning
CLOCK (Pin 10 / 11)	Step clock input	Rising-edge-triggered state machine advance; minimum pulse width 1 µs ensures reliable stepping at up to 1 MHz effective step rate.
CW/CCW (Pin 2 / 11)	Direction control	Static logic level sets rotation direction; tied to GND/+5 V if unused to prevent floating-state missteps.
SENSEA/SENSEB (Pins 3/10 / 13/25)	Current sense return	Connects to ground side of external shunt resistors; 1 µs internal blanking prevents false overcurrent trips from diode recovery.
RCA/RCB (Pins 4/9 / 14/24)	PWM off-time timing	RC network sets monostable t_OFF; value directly determines current decay rate and chopper stability.
VREFA/VREFB (Pins 24/11 / 26/11)	Current reference input	Analog voltage (0–5 V) sets peak motor phase current; 5 mV offset ensures ≤0.5% current regulation error.
EN (Pin 14 / 29)	Global enable	Active-low; internally tied to overcurrent/thermal fault drain - requires series resistor (2.2–180 kΩ) when driven by open-collector source.
VBOOT (Pin 15 / 30)	Bootstrap supply	Drives high-side gate; generated by internal 600 kHz oscillator + external charge pump (C_BOOT = 220 nF, C_P = 10 nF).
GND (Pins 6,7,18,19 / 1,18,19,36)	Power/thermal ground	Multiple pins serve dual role: signal reference and heat conduction path to PCB; critical for thermal resistance ≤1 °C/W (j-case).

Key Features

Feature	Design Value
Dual independent constant t_OFF PWM controllers	Enables asymmetric current regulation per phase - essential for torque balancing in unbalanced winding configurations.
Fast/slow decay mode selection	CONTROL pin toggles decay behavior: fast decay improves high-speed torque response; slow decay reduces power loss at low speed.
Non-dissipative overcurrent protection	Detects overcurrent via sense resistor without shunt power loss; triggers immediate shutdown without external sensing components.
Integrated fast freewheeling diodes	Eliminates need for 8 external Schottky diodes - reduces BOM count, PCB area, and forward-voltage drop losses (~1.15 V typical).
Half/full step decoding logic	On-chip state machine generates correct phase sequencing from CLOCK/CW/CCW/ HALF-FULL inputs - removes MCU firmware overhead.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bipolar stepper motor driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TB6600HG	Higher voltage rating (up to 50 V), but only 4 A peak current; no integrated charge pump - requires external bootstrap circuitry.	Lacks half-step decoding logic and internal fast freewheeling diodes; needs external diodes and MCU-based sequencing.	Prefer when supply >48 V is required and board space allows added components; avoid for compact, low-noise designs.
DRV8825	Lower max supply (45 V), 2.2 A RMS (4.5 A peak); microstepping up to 1/32, but no fast/slow decay selection or non-dissipative OCP.	Designed for microstepping-focused applications; lacks dedicated half/full step logic and thermal shutdown hysteresis.	Choose for high-resolution microstepping where torque consistency matters less than positional granularity; not suitable for 5.6 A loads.

Compared with TB6600HG and DRV8825, the L6208PD013TR uniquely combines 5.6 A peak current, integrated charge pump, on-chip half/full step logic, and non-dissipative overcurrent protection - making it optimal for space-constrained, high-torque industrial stepper systems requiring minimal external components and robust fault handling.

FAQ

What is the maximum allowable motor supply voltage for L6208PD013TR?

The absolute maximum supply voltage is 60 V, but the recommended operating range is 8–52 V per the datasheet. Operation above 52 V risks exceeding safe operating area limits and may trigger undervoltage lockout during transients. At 52 V, R_DS(ON) remains within spec (0.59 Ω max at 125 °C), ensuring thermal stability with proper PCB copper area.

How does the non-dissipative overcurrent protection work without external sensing components?

The protection monitors voltage across the internal low-side MOSFETs' R_DS(ON) during conduction - eliminating need for external shunts. When sensed current exceeds 5.6 A (typ), the EN pin is pulled low via an internal open-drain MOSFET, disabling both bridges. Recovery requires cycling EN or resetting the device.

Can L6208PD013TR drive unipolar stepper motors?

No - the L6208 is designed exclusively for two-phase bipolar stepper motors with center-tapped windings. Its dual full-bridge topology cannot replicate the single-polarity switching required for unipolar operation. Attempting unipolar connection risks incorrect current paths and potential device damage.

What is the minimum external component count needed for basic operation?

Minimum components: 2 × sense resistors (SENSEA/SENSEB), 2 × RC networks (RCA/RCB), 2 × bootstrap capacitors (C_BOOT, C_P), 1 × pull-up resistor on EN (100 kΩ), and 1 × decoupling capacitor per VS rail (100 nF + 10 µF). No external diodes or current-sense amps are required due to on-chip integration.
